■DEEP GROOVE BALL BEARINGS O-rings
Creep-Free BearingsTM
700
Creep resistance, N
Creep-Free Bearings, which come with two O-rings mounted in the outer ring, help to prevent the occurrence of creep by restricting the amount of clearance between the outer ring and housing. No special machining is required; bearings can be used with the same housing as standard bearings. In creep limit load tests, the more housing clearance is reduced, the greater the improvement in creep prevention, due to the tension of the O-ring mounted in the outer ring.

BEARINGS TABLE
■DEEP GROOVE BALL BEARINGS MAXIMUM TYPE BALL BEARINGS Maximum Type Ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel. MAGNETO BEARINGS The groove in the inner ring is a little shallower than that of deep groove ball bearings and one side of the outer ring is relieved. Consequently, the outer ring is separable, which makes it convenient for mounting. Pressed cages are standard, but for high speed applications, machined synthetic resin cages are used.
PRECAUTIONS FOR USE OF DEEP GROOVE BALL BEARINGS For deep groove ball bearings, if the bearing load is too small during operation, slippage occurs between the balls and raceways, which may result in smearing. The higher the weight of balls and cage, the higher this tendency becomes, especially for large bearings. If very small bearing loads are expected, please contact NSK for selection of an appropriate bearing.

■DEEP GROOVE BALL BEARINGS TECHNICAL DATA Radial and Axial Internal Clearances and Contact Angles for Single Row Deep Groove Ball Bearings (1) Radial and Axial Internal Clearances The internal clearance in single row bearings has been specified as the radial internal clearance. The bearing internal clearance is the amount of relative displacement possible between the bearing rings when one ring is fixed and the other ring does not bear a load. The amount of movement along the direction of the bearing radius is called the radial clearance, and the amount along the direction of the axis is called the axial clearance. The geometric relation between the radial and axial clearance is shown in Fig. 1.
From geometric relationships, various equations for clearance, contact angle, etc. can be derived.

Because (re+ri –Dw) is a constant, it is apparent why fixed relationships between Dr, Da and a exist for all the various bearing types. As was previously mentioned, the clearances for deep groove ball bearings are given as radial clearances, but there are specific applications where it is desirable to have an axial clearance as well. The relationship between deep groove ball bearing radial clearance D r and axial clearance D a is given in Equation (4). To simplify, Fig. 1 Relationship Between Δ r and Δ a

(2) R elation between Radial Clearance and Contact Angle Single-row deep groove ball bearings are sometimes used as thrust bearings. In such applications, it is recommended to make the contact angle as large as possible. The contact angle for ball bearings is determined by the geometric relationship between the radial clearance and the radii of the inner and outer grooves. Using Equations (1) to (6), Fig. 3 shows the particular relationship between the radial clearance and contact angle of 62 and 63 series bearings. The initial contact angle, a0, is the initial contact angle when the axial load is zero. Application of any load to the bearing will change this contact angle. If the initial contact angle a0 exceeds 20°, it is necessary to check whether or not the contact area of the ball and raceway touch the edge of raceway shoulder. (Refer to Section 8.1.2)
For applications when an axial load alone is applied, the radial clearance for deep groove ball bearings is normally greater than the normal clearance in order to ensure that the contact anlgle is relatively large. The initial contact angles for C3 and C4 clearances are given for selected bearing sizes in Table 2 below.

Features and Operating Temperature Range of Ball Bearing Seal Material The sealed ball bearing is a ball bearing with seals as shown in Figs. 1 and 2. There are two seal types: non-contact seal type and contact seal type. For rubber seal material, nitrile rubber is used for general purpose and poly-acrylic rubber, silicon rubber, and fluoric rubber are used depending on temperature conditions. These rubbers have their own unique nature and appropriate rubber must be selected by considering the particular application environment and running conditions. Table 1 shows principal features of each rubber material and the operating temperature range of the bearing seal. The operating temperature range of Table 1 is a guideline for continuous operation. Thermal aging of rubber is related to the temperature and time. Rubber may be used in a much wider range of operating temperatures depending on the operating time and frequency. In the non-contact seal, heat generation due to friction on the lip can be ignored. And thermal factors, which cause aging of the rubber, are physical changes due to atmospheric and bearing temperatures. Accordingly, increased hardness or loss of elasticity due to thermal aging exerts only a negligible effect on the seal performance. A rubber non-contact seal can thus be used in an expanded range of operating temperatures greater than that for a contact seal. But there are some disadvantages. The contact seal has a problem with wear occurring at the seal lip due to friction, thermal plastic deformation, and hardening. When friction or plastic deformation occurs, the contact pressure between the lip and slide surface decreases, resulting in a clearance. This clearance is minimum and does not cause excessive degradation of sealing performance (for instance, it does not allow dust entry or grease leakage). In most cases, this minor plastic deformation or slightly increased hardness presents no practical problems.
C 016
However, in external environments with dust and water in large quantity, the bearing seal is used as an auxiliary seal and a principal seal should be provided separately. As so far described, the operating temperature range of rubber material is only a guideline for selection. Since heat resistant rubber is expensive, it is important to understand the temperature conditions so that an economical selection can be made. Due attention should also be paid not only to heat resistance, but also to the distinctive features of each rubber.

Free Space and Grease Filling Amount for Deep Groove Ball Bearings Grease lubrication can simplify the bearing’s peripheral construction. In place of oil lubrication, grease lubrication is now employed along with enhancement of the grease quality for applications in many fields. It is important to select a grease appropriate to the operating conditions. Due care is also necessary as to the filling amount, since too much or too little grease greatly affects the temperature rise and torque. The amount of grease needed depends on such factors as housing construction, free space, grease brand, and environment. A general guideline is described next. First, the bearing is filled with an appropriate amount of grease. In this case, it is essential to push grease onto the cage guide surface. Then, the free space, whic excludes the spindle and bearing inside the housing, is filled with an amount of grease as shown next: 1/2 to 2/3 1/3 to 1/2
when the bearing speed is 50% or less of the allowable speed specified in the catalog. when the bearing speed is 50% or more.
Roughly, low speeds require more grease while high speeds require less grease. Depending on the particular application, the filling amount may have to be reduced further to reduce the torque and to prevent heat generation. When the bearing speed is extremely low, on the other hand, grease may be packed almost full to prevent dust and water entry. Accordingly, it is necessary to know the extent of the housing’s free space for the specific bearing to determine the correct filling amount. As a reference, the volume of free space is shown in Table 1 for an open type deep groove ball bearing.
C 018
Note that the free space of the open type deep groove ball bearing is the volume obtained by subtracting the volume of the balls and cage from the space formed between inner and outer rings.

■ANGULAR CONTACT BALL BEARINGS DESIGN, TYPES, AND FEATURES Contact angle
α
SINGLE-ROW ANGULAR CONTACT BALL BEARINGS Since these bearings have a contact angle, they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required. (Refer to Chapter 9, Preload, Page A192). Usually, the cages for angular contact ball bearings with a contact angle of 30° (Symbol A) or 40°(Symbol B) are in accordance with Table 1,but depending on the application, machined synthetic resin cages or molded polyamide resin cages are also used. The basic load ratings given in the bearing tables are based on the standard cages. Though the figures in the bearing tables (Pages C086 to C101; bearing bore diameters of 10 to 120) show bearings with single-shoulder-type inner rings, both-shoulder-type bearings are also available. Please consult NSK for more detailed information.

In addition, for bearings with the same serial number, if the type of cages are different, the number of balls may also be different. In such a case, the load rating will differ from the one listed in the bearing tables. Angular Contact Ball Bearings with contact angles of 15° (Symbol C) and 25° (Symbol A5) are primarily for high precision or high speed applications, and molded polyamide cages (Symbol TYN) or machined brass cages or synthetic resin cages (Symbol T) are used. The maximum operating temperature of molded polyamide cages is 150°C. MATCHED ANGULAR CONTACT BALL BEARINGS The types and features of matched angular contact ball bearings are shown in Table 2.

Arrangement
Features
Back-to-back (DB) (Example) 7208 A DB
Radial loads and axial loads in both directions can be sustained. Since the distance between the effective load centers a0 is big, this type is suitable if moments are applied.
Face-to-face (DF) (Example) 7208 B DF
Radial loads and axial loads in both directions can be sustained. Compared with the DB Type, the distance between the effective load centers is small, so the capacity to sustain moments is inferior to the DB Type.
Tandem (DT) (Example) 7208 A DT
Radial loads and axial loads in one direction can be sustained. Since two bearings share the axial load, this arrangement is used when the load in one direction is heavy.
NSKHPS ANGULAR CONTACT BALL BEARINGS In comparison with standard angular contact ball bearings, these bearings have high capacity, high limiting speed, and highly accurate universal matching as the features. The molded polyamide cages are standard specification for the HPS type. C 072

FOUR-POINT CONTACT BALL BEARINGS The inner ring is split radially into two pieces. Their design allows one bearing to sustain significant axial loads in either direction. The contact angle is 35°, so the axial load capacity is high. This type is suitable for carrying pure axial loads or combined loads where the axial loads are high. The cages are made of machined brass. □ Formulation of Bearing Numbers Four-Point Contact Ball Bearings Bearing number ： example

■ANGULAR CONTACT BALL BEARINGS PRECAUTIONS FOR USE OF ANGULAR CONTACT BALL BEARINGS Under severe operating conditions where the speed and temperature are close to their limits, lubrication is marginal, vibration and moment loads are heavy, they may not be suitable, particularly for certain types of cages. In such a case, please consult with NSK beforehand. And if the load on angular contact ball bearings becomes too small, or if the ratio of the axial and radial loads for matched bearings exceeds ‘e’ (e is listed in the bearings tables) during operation, slippage occurs between the balls and raceways, which may result in smearing. Especially with large bearings since the weight of the balls and cage is high. If such load conditions are expected, please consult with NSK for selection of the bearings.

INTERNAL CLEARANCES MATCHED ANGULAR CONTACT BALL BEARINGS······· Table 8.18 (Page A174) Matched angular contact ball bearings with precision better than P5 are primarily used in the main spindles of machine tools, so they are used with a preload for rigidity. For convenience of selection, internal clearances are adjusted to produce Very Light, Light, Medium, and Heavy Preloads. Their fitting is also special. Concerning these matters, please refer to Tables 9.1 and 9.5 (Pages A194 and A197). The clearance (or preload) of matched bearings is obtained by axially tightening a pair of bearings till the side faces of their inner or outer rings are pressed against each other.

LIMITING SPEEDS (Grease/Oil) In cases of single-row and matched angular contact ball bearings, The limiting speeds (grease) and limiting speeds (oil) listed in the bearing table are for bearings with standard cage. For those with option cages, limiting speeds (grease/oil) may differ depending on cages. Please consult with NSK. For example, limiting speeds (grease/oil) of machined cage (No symbol) is 1.25 times higher than pressed cage. The limiting speeds of bearings with contact angles of 15° (Symbol C) and 25° (Symbol A5) are for bearings with precision of P5 and better (with machined synthetic-resin cages (T) or molded polyamide cages (TYN)). The limiting speeds listed in the bearing tables should be adjusted depending on the bearing load conditions. Also, higher speeds are attainable by making changes in the lubrication method, cage design, etc. Refer to Page A098 for detailed information.

■ANGULAR CONTACT BALL BEARINGS TECHNICAL DATA The angular ball bearing is available in various kinds which are independent of the combinations of bearing series, contact angle, and cage type. The free space of the bearing used most frequently is described below. Table 1 shows the free space of a bearing with a pressed cage for general use and Table 2 shows that of a bearing with a high-tension brass machined cage. The contact angle symbols A, B, and C in each table refer to the nominal contact angle of 30°, 40°, and 15° of each bearing.
Free Space of Angular Contact Ball Bearings Angular contact ball bearings are used in various components, such as spindles of machine tools, vertical pump motors, and worm gear reducers. This kind of bearing is used mostly with grease lubrication. But such grease lubrication may affect the bearing in terms of temperature rise or durability. To allow a bearing to demonstrate its full performance, it is essential to fill the bearing with the proper amount of a suitable grease. A prerequisite for this job is a knowledge of the bearing’s free space.

■ANGULAR CONTACT BALL BEARINGS Dynamic Equivalent Load of Triplex Angular Contact Ball Bearings Three separate single-row bearings may be used side by side as shown in the figure when angular contact ball bearings are to be used to carry a large axial load. There are three patterns of combination, which are expressed by combination symbols of DBD, DFD, and DTD. As in the case of single-row and double-row bearings, the dynamic equivalent load, which is determined from the radial and axial loads acting on a bearing, is used to calculate the fatigue life for these combined bearings. Assuming the dynamic equivalent radial load as Pr, the radial load as Fr, and axial load as Fa, the relationship between the dynamic equivalent radial load and bearing load may be approximated as follows: Pr =XFr +YFa . ........ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . (1) where, X : Radial load factor Y : Axial load factor See Table 1 The axial load factor varies with the contact angle. In an angular contact ball bearing, whose contact angle is small, the contact angle varies substantially when the axial load increases. A change in the contact angle can be expressed by the ratio between the basic static load rating C0r and axial load F a. Accordingly, for the angular contact ball bearing with a contact angle of 15°, the axial load factor at a contact angle corresponding to this ratio is shown. If the angular contact ball bearings have contact angles of 25°, 30° and 40°, the effect of change in the contact angle on the axial load factor may be ignored and thus the axial load factor is assumed as constant.

■ANGULAR CONTACT BALL BEARINGS Angular Clearances in Double-Row Angular Contact Ball Bearings The angular clearance in double-row bearings is defined in exactly the same way as for single-row bearings; i.e., with one of the bearing rings fixed, the angular clearance is the greatest possible angular displacement of the axis of the other ring. Since the angular clearance is the greatest total relative displacement of the two ring axes, it is twice the possible angle of inner and outer ring movement (the maximum angular displacement in one direction from the center without creating a moment). The relationship between axial and angular clearance for double-row angular contact ball bearings is given by Equation (1) below.

D a=2m0 sina0+ qRi – 1– cosa0+ ql 2m0
4m0
The relationship between radial clearance D r and axial clearance D a for double-row angular contact ball bearings was explained in pages C086 and C087. Based on those equations, Fig. 2 shows the relationship between angular clearance q and radial clearance D r.

■ANGULAR CONTACT BALL BEARINGS Relationship between Radial and Axial Clearances in Double-Row Angular Contact Ball Bearings The relationship between the radial and axial internal clearances in double-row angular contact ball bearings can be determined geometrically as shown in Fig. 1 below.
The following relations can be derived from Fig. 1: m0 sin a0=m0sin aR+ D a . ........................... (1) 2
However, when the clearance is relatively large, (when D r /Dw > 0.002) the error in Equation (7) can be quite large. The contact angle aR is independent of the radial
clearance; however, the initial contact angle a0 varies with the radial clearance when the inner or outer ring is displaced axially. This relationship is given by Equation (2).
m0 cos a0=m0cos aR+ D r . . ......................... (2) 2
since sin2a0=1–cos2a0, (m0 sin a0)2=m02–(m0 cos a0)2 . ..................... (3) Combined Equations (1), (2), and (3), we obtain:
(m sin a + D ) =m – (m cosa – D ) 0

aR is 25° for 52 and 53 series bearings and 32° for 32 and 33 series bearings. If we set aR equal to 0°, Equation (5) becomes: 2 D a=2 m02– m0– D r

The value of m0 is dependent on the inner and outer ring groove radii. The relation between D r and D a, as given by Equation (5), is shown in Figs. 2 and 3 for NSK 52, 53, 32, and 33 series double-row angular contact ball bearings. When the clearance range is small, the axial clearance is given approximately by D a≒D r cot aR . ..................................... (7)

BEARINGS TABLE
■SELF-ALIGNING BALL BEARINGS DESIGN, TYPES, AND FEATURES The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. This type is recommended when the alignment of the shaft and housing is difficult and when the shaft may bend. Since the contact angle is small, the axial load capacity is low. Pressed steel cages are usually used.
PROTRUSION AMOUNT OF BALLS Among self-aligning ball bearings, there are some in which the balls protrude from the side face as shown below. This protrusion amount b1 is b1 listed in the following table. b1
Bearing No.

INTERNAL CLEARANCE····································· Table 8.13 (Page A170) PERMISSIBLE MISALIGNMENT The permissible misalignment of self-aligning ball bearings is approximately 0.07 to 0.12 radian (4° to 7°) under normal loads. However, depending on the surrounding structure, such an angle may not be possible. Use care in the structural design.

Vibration
For a given bearing number, if the type of cage is not the standard one, the number of rollers may vary; in such a case, the load rating will differ from the one listed in the bearing tables. Among the NN Type of double-row bearings, there are many of high precision that have tapered bores, and they are primarily used in the main spindles of machine tools. Their cages are either molded polyphenylenesulfide (PPS) or machined brass.
C 124
⑥Radial
PRECAUTIONS FOR USE OF CYLINDRICAL ROLLER BEARINGS If the load on cylindrical roller bearings becomes too small during operation, slippage between the rollers and raceways occurs, which may result in smearing. Especially with large bearings since the weight of the roller and cage is high. In case of strong shock loads or vibration, pressed-steel cages are sometimes inadequate. If very small bearing load or strong shock loads or vibration are expected, please consult with NSK for selection of the bearings. Bearings with molded polyamide cages (ET type) can be used continuously at temperatures between — 40 and 120°C. If the bearings are used in gear oil, nonflammable hydraulic oil, or ester oil at a high temperature over 100°C, please contact NSK beforehand.

LIMITING SPEEDS (Mechanical) In some single row cylindrical roller bearings, optional cage types are available for special purposes or customer requests. The limiting speeds (mechanical) in the bearing tables are the values for the standard cage type. Please consult with NSK about the limiting speeds(mechanical) of optional cage.
LIMITING SPEEDS (Grease/Oil) The limiting speeds (grease) and limiting speeds (oil) listed in the bearing tables should be adjusted depending on the bearing load condition. Also, higher speeds are attainable by making changes in the lubrication method, cage design, etc. Refer to page A098 for detailed information.

■CYLINDRICAL ROLLER BEARINGS TECHNICAL DATA made from pressed steel or from machined hightension brass. When determining the grease filling amount, please refer to Tables 1 and 2 which show the free space of NU type bearings. (By the way, the cylindrical roller bearing type is used most frequently).
Free Space of Cylindrical Roller Bearings Cylindrical roller bearings employ grease lubrication in many cases because it makes maintenance easier and simplifies the peripheral construction of the housing. It is essential to select a grease brand appropriate for the operating conditions while paying due attention to the filling amount and position of the bearing as well as its housing.
For types other than the NU type, the free space can be determined from the free space ratio with the NU type. Table 3 shows the approximate free space ratio for each type of cylindrical roller bearing. For example, the free space of NJ310 with a pressed steel cage may be calculated approximately at 47 cm3. This result was calculated by multiplying the free space 52 cm3 of NU310 in Table 1 by the space ratio 0.90 for the NJ type (Table 3).
The cylindrical roller bearings can be divided into NU, NJ, N, NF, NH, and NUP types of construction according to the collar, collar ring, and position of the inner or outer ring ribs. Even if bearings belong to the same dimension series, they may have different amounts of free space. The free space also differs depending on whether the cage provided is

Tolerances and Running Accuracy··················Table 7.2 (Pages A128 to A131) Single-Row Double-Row
Recommended Fits
Cageless, full-complement cylindrical roller bearings have the maximum possible number of rollers and can sustain much heavier loads than cylindrical roller bearings of the same size with cages. On the other hand, high-speed capability is inferior to the bearings with cages. The open-type single- and double-row bearings are mostly used in general industrial applications at low speed and under heavy load, and the shieldedtype double-row bearings are often used in crane sheaves.

The outer and inner rings and rollers are non-separable since a retaining snap ring is installed at the side opposite the outer ring rib. They can sustain axial loads in only one direction.
NNCF
C 162
Permissible Misalignment The permissible misalignment of full-complement single-row cylindrical roller bearings is generally 0.0006 radian (2’) under normal load. For double-row bearings, nearly on misalignment is allowed.
NNCF is a double-row version of NCF. They can sustain heavy radial loads.

FULL-COMPLEMENT CYLINDRICAL ROLLER BEARINGS FOR SHEAVES
RECOMMENDED FITS AND INTERNAL CLEARANGES
DESIGN, TYPES, AND FEATURES Cylindrical Roller Bearings for sheaves are specially designed thin-walled, broad-width, full-complement type double-row cylindrical roller bearings, but they are widely used also for general industrial machines running at low speed and under heavy loads. There are several series as shown in Table 1. Table 1 Series of Cylindrical Roller Bearings for Sheaves

Free-End
RS-48E4 Open Type Without Snap Ring RS-49E4
RSF-48E4 RSF-49E4
Without Snap Ring RS-50 Shielded Type RS-50NR With Snap Ring
—
Since all are non-separable type bearings, the inner and outer rings cannot be separated, but the RSF type can be used as a free-end bearing. In this case, the permissible axial displacement is listed in the bearing tables. Since cylindrical roller bearings for sheaves are a double-row, fullcomplement type, they can withstand heavy shock loads and moments and have sufficient axial load capacity for use in sheaves. Since the shielded type is a kind of bearing unit, the number of parts surrounding the bearing can be reduced, so it allows for a simple compact design. The surface of these bearings is treated for rust prevention.

Design and Features
RS-48E4 RS-49E4
Double-row outer ring with center rib, two single-row inner rings with ribs. The outer and inner rings and rollers are non-separable since there are two retaining snap rings at the sides of the outer ring. They can suntain an axial load in either direction so they can be used as fixed-end bearings. An oil groove and holes are provided at the center of the outer ring.
RSF-48E4 RSF-49E4
Double-row outer ring without ribs, double-row inner ring with three ribs. The outer and inner rings and rollers are non-separable since there is a retaining snap ring at the middle of the outer ring. They can be used as free-end bearings. The permissible axial movement is listed in the dimensional tables. An oil groove and holes are provided at the center of the outer ring.

When used with outer ring rotation for sheaves or wheels, the fit and radial internal clearance should conform to Table 3. Table 3 Fits and Internal Clearances for Cylindrical Roller Bearings for Sheaves Operating Conditions

TOLERANCES AND RUNNING ACCURACY···························· Table 7.2 (Pages A128 to A131)
Both sides shielded, double-row outer ring with center rib, two inner rings with ribs. They can sustain an axial load in either direction. They are prelubricated, but it is possible to replenish the grease through an oil groove and holes in parts mating with the inner rings. If there are snap rings at the outside of the outer ring, this type becomes RS-50NR. They are surface-treated for rust prevention.

■TAPERED ROLLER BEARINGS DESIGN, TYPES, AND FEATURES
Contact angle
Tapered roller bearings are designed so the apices of the cones formed by the raceways of the cone and cup and the conical rollers all coincide at one point on the axis of the bearing. When a radial load is imposed, an axial force component occurs; therefore, it is necessary to use two bearings in opposition or some other multiple arrangement. For metric-design medium-angle and steep-angle tapered roller bearings, the respective contact angle symbol C or D is added after the bore number. For normal-angle tapered roller bearings, no contact angle symbol is used. Medium-angle tapered roller bearings are primarily used for the pinion shafts of differential gears of automobiles. Among those with high load capacity(HR series), some bearings have the basic number suffixed by J to conform to the specifications of ISO for the cup back face raceway diameter, cup width, and contact angle. Therefore, the cone assembly and cup of bearings with the same basic number suffixed by J are internationally interchangeable. Among metric-design tapered roller bearings specified by ISO 355, there are those having new dimensions that are different than the dimension series 3XX used in the past. Part of them are listed in the bearing tables. They conform to the specifications of ISO for the smaller end diameter of the cup and contact angle. The cone and cup assemblies are internationally interchangeable. The bearing number formulation, which is different than that for past metric design, is as follows:
Besides metric design tapered roller bearings, there are also inch design bearings. For the cone assemblies and cups of inch design bearings, except four-row tapered roller bearings, the bearing numbers are approximately formulated as follows: Example: — LM 1 19 49 — — — — Load Limit Symbol
Contact Angle Symbol
Design No.
Additional Symbol
For tapered roller bearings, besides single-row bearings, there are also various combinations of bearings. The cages of tapered roller bearings are usually pressed steel.

Series No.
Two standard bearings are combined. The bearing clearances are adjusted by cone spacers or cup spacers. The cones and cups and spacers are marked with serial numbers and

mating marks. Components with the same serial number can

be assembled referring to the matching symbols.
The KBE type is a back-to-back arrangement of bearings with the cup and spacer integrated, and the KH type is a face-toface arrangement in which the cones are integrated. Since the bearing clearance is adjusted using spacers, it is necessary

for components to have the same serial number for assembly with reference to matching symbols.

INTERNAL CLEARANCE
BEARINGS TABLE
PRECAUTIONS FOR USE OF TAPERED ROLLER BEARINGS 1. If the load on tapered roller bearings becomes too small, or if the ratio of the axial and radial loads for matched bearings exceeds ‘e’(e is listed in the bearing tables)during operation, slippage between the rollers and raceways occurs, which may result in smearing. Especially with large bearings since the weight of the rollers and cage is high. If such load conditions are expected, please contact NSK for selection of the bearings. 2. C onfirm the dimension of “Abutment and Fillet Dimensions” of Da, Db, Sa, Sb at the time of the HR series adoption.
METRIC DESIGN TAPERED ROLLER BEARINGS (Matched and Double-Row)······································· Table 8.17 (Page A173) INCH DESIGN TAPERED ROLLER BEARINGS (Matched and Double-Row)······································· Table 8.17 (Page A173)
DIMENSIONS RELATED TO MOUNTING The dimensions related to mounting tapered roller bearings are listed in the bearing tables. Since the cages protrude from the ring faces of tapered roller bearings, please use care when designing shafts and housings. When heavy axial loads are imposed, the shaft shoulder dimensions and strength must be sufficient to support the cone rib.
PERMISSIBLE MISALIGNMENT The permissible misalignment angle for tapered roller bearings is approximately 0.0009 radian (3´).
LIMITING SPEEDS (GREASE/OIL) The limiting speeds (grease) and limiting speeds (oil) listed in the bearing tables should be adjusted depending on the bearing load condition. Also, higher speeds are attainable by making changes in the lubrication method, cage design, etc. Refer to page A098 for detailed information.

BEARINGS TABLE
■TAPERED ROLLER BEARINGS TECHNICAL DATA Free Space of Tapered Roller Bearings The tapered roller bearing can carry radial load and uni-direction axial loads. It offers high capacity. This type of bearing is used widely in machine systems with relatively severe loading conditions in various combinations by opposing or combining single-row bearings. With a view towards easier maintenance and inspection, this kind of bearing is lubricated with grease in most cases. It is important to select a grease appropriate to the operating conditions and to use the proper amount of grease for the housing internal space. As a reference, the free space of a tapered roller bearing is shown in Table 6. The free space of a tapered roller bearing is the space (shadowed portion) of the bearing outer volume less the inner and outer rings and cage, as shown in Fig. 1. The bearing is filled so that grease reaches the inner ring rib surface and pocket surface in sufficient amount. Due attention must also be paid to the grease filling amount and state, especially if grease leakage occurs or maintenance of low running torque is important.

■SPHERICAL ROLLER BEARINGS DESIGN, TYPES, AND FEATURES B179 B179 Shown in the figures, types EA, C, CD, CA, which are designed for high load capacity, are
available. Types EA, C and CD have pressed steel cages, and type CA has machined brass cages. The EA type bearings listed here are classified as NSKHPSTM bearings, which offer particularly high load-carrying capacity, high limiting speeds, and are highly functional under high-temperature operating conditions of up to 200°C. An oil groove andB179 holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4. To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in theEA bearing is limited. The number and EA dimensions of the oil groove and holes are shown in Tables 1 and 2. When bearings with a hole for a locking pin to prevent outer ring rotation are required, please B179inform NSK.

If the load on spherical roller bearings becomes too small during operation or if the ratio of axial and radial loads is larger than the value of ‘e’ (listed in the bearing tables), slippage occurs between the rollers and raceways, which may result in smearing. The higher this tendency becomes, especially for large spherical roller bearings. If very small bearing loads are expected, please contact NSK for selection of an appropriate bearing.

■SPHERICAL ROLLER BEARINGS TECHNICAL DATA Free Space of Spherical Roller Bearings The spherical roller bearing has self-aligning ability and capacity to carry substantially large radial and bi-axial loads. For these reasons, this bearing is used widely in many applications. Application problems include a long span, which causes substantial deflection of the shaft, as well as installation errors and axial misalignment. These bearings may be exposed to a large radial or shock loads. By the way, this bearing is used in plumber blocks. Grease lubrication is common for spherical roller bearings because it simplifies the seal construction around the housing and makes maintenance and inspection easier. In this case, it is important to select a grease appropriate to the operating conditions and to fill the bearing with the proper amount of grease considering the housing internal space.
As a reference, the bearing free space for conventional types plus four other types (EA, C, CD, and CA) is shown in Table 1. Under general operating conditions, it is appropriate to pack a large quantity of grease into the bearing internal space and to pack grease into the housing internal space other than the bearing itself, to the extent of 1/3 to 2/3 that of the free space.

■SPHERICAL ROLLER BEARINGS
Measurement of Bearing Clearance For the bearing mounting, the measurement of internal bearing clearance is a most important task. Before handling the bearing and measuring the internal bearing clearance, be sure to wear thin rubber gloves. (If a bearing is touched by a bare hand, the touched part may rust.) When measuring the internal bearing clearance, pay careful attention so that the rollers are positioned correctly.
1. Measurement of Bearing Clearance To measure only internal bearing clearance, set the bearing standing upright (vertically) on a flat surface, while holding its outer ring with one hand. While paying attention not to incline the inner and outer rings, stabilize the rollers by turning the inner ring to the right and left by about one half to one full rotation. Adjust rollers until one randomly chosen roller of the double rows is positioned to be exactly at the top. Now, the internal clearance is measured with a thickness gauge. The measurement position and measured point vary slightly depending on the size of the outer ring outside diameter. 1.1 B earing Outside Diameter Is Smaller Than 200 mm Insert the thickness gauge between rollers of 2 rows which have a roller positioned exactly at the top of the bearing and outer ring. Now, measure the internal clearance (D r). (Fig. 1) 1.2 B earing Outside Diameter Is Larger Than 200 mm Insert the thickness gauge between the rollers of the 2 rows, which each have been positioned to be exactly at the top, and outer ring and between 2 rows of bearing at symmetrical position relative to the bearing center, then measure the respective
internal clearance of the bearing. (Fig. 2) For the internal bearing clearance (D r), take that value measured between 2 rows of just top of bearing and outer ring as respectively D rT 1 and D rT 2 and that value measured just at top of the bearing as D rT.
D rT = 1/2 (D rT 1 + D rT 2) Among internal clearances between 2 rows of rollers that are symmetrical relative to the bearing center and outer ring, take that measurement between2 rows of rollers of left side respectively as D rL1 and D rL2. The internal clearance on the left side of the bearing is D rL:
DrL = 1/2 (DrL1 + DrL2) Take that measurement between 2 rows of rollers of right side respectively as DrR1 and DrR2. The internal clearance of the right side of the bearing is DrR:
DrR = 1/2 (DrR1 + DrR2)
the measurement point varies slightly depending on the size of the outer ring outside diameter.
DrS = 1/2 (DrS1 + DrS2) Among internal clearances between 2 rows of rollers symmetrical relative to the bearing center and outer ring, take that value measured between 2 rows of rollers of left side respectively as DrL1 and DrL2 and the internal clearance of left side of bearing as DrL.
2.1 Bearing Outside Diameter Is Smaller Than 200 mm Insert the thickness gauge between rollers of 2 rows of just at the bottom of the bearing and outer ring and measure the internal clearance (DrS).(Fig. 3) 2.2 B earing Outside Diameter Is Larger Than 200 mm Insert the thickness gauge between rollers of 2 rows that are positioned just at the bottom of bearing and outer ring and between 2 rows of bearing rollers symmetrical relative to the bearing center, then, measure the respective internal clearance of the bearing. (Fig. 3) For the internal bearing clearance (Dr), take the measurement when the roller is positioned exactly at the bottom, since the bearing has 2 rows, two values must be measured. The bearing internal clearance is DrS1 and DrS2 while that value measured at the exact bottom of the bearing is DrS.
DrL = 1/2 (DrL1 + DrL2) The internal clearances measured between 2 rows of rollers on the right side respectively as DrR1 and DrR2. The internal clearance of right side of bearing is DrR.
DrR = 1/2 (DrR1 + DrR2) The internal bearing clearance (Dr) is given by the following equation:
Dr = 1/2 (DrS + DrL + DrR)
The internal bearing clearance (Dr) is given by the following equation:
Δ rT
Dr = 1/2 (DrT + DrL + DrR) 2. M easuring Bearing Clearance When Mounted on Shaft or Sleeve Basically, the measurement of the clearance is taken when the outer ring of bearing hangs down from rollers. At first, while holding the bearing up-right, rotate the outer ring in the clockwise and counter-clockwise directions by one half to one full rotation until both rows have a randomly chosen roller positioned exactly at the bottom. The clearance is measured with a thickness gauge but

3. T emperature Equilibrium When Taking Measurements To ensure accurate bearing measurement of the internal clearance or dimensions, the temperature of the measurement instrument and that of the components to be measured must be brought to the same temperature. Especially, if the bearing is mounted by using an oil heating tank or induction heater, then measure the internal clearance only after a complete cool down. For example, if a bearing is brought from the warehouse to the measurement place, the temperature of the stored bearing may still be high, thus, if the clearance or dimension were measured wihtout confirming the bearing temperature, the measured value may be wrong. For a large bearing with an outer ring outside diameter that is larger than 400 mm, if a clearance or dimension measurement is necessary, it is recommended to leave the unpacked bearing for about 24 hours on the surface plate, before making a clearance or dimension measurement. Put the end face of the bearing on a surface plate prior to measurement to ensure a measurement with both objects at the same temperature.
4. C learance Adjustment When Mounting Bearing on a Tapered Shaft or Sleeve Mount the bearing with its inner ring having a taperedbore to the tapered shaft or sleeve (adapter, removable sleeve). When pushing in the bearing to the tapered shaft or sleeve, the inner ring of bearing is widened resulting in increase of “interference” and reduction of internal clearance. It is important to give proper interference and internal clearance when mounting the bearing. Next, we show the reduction amount of the clearance to achieve the proper mounting. Mounting of spherical roller bearings having tapered bore Table 2 When mounting a bearing, each time the bearing is pushed further onto the tapered shaft or sleeve, measure the variation of internal clearance and repeat the above procedure until the clearance reduction amount to the specified value listed in the Table 2 is attained. This procedure is called “Clearance adjustment” and when the clearance reduction amount is attained, the clearance necessary for bearing running is secured. The confirmation of the clearance reduction amount by measurement with a thickness gauge is very important. Depending on the method of clearance adjustment, the measured value obtained with the thickness gauge may not be correct. Therefore, the following corrective procedure must be executed. 1. In case to heat When the temperatures of bearing and shaft are both at the same room temperature, measure again the clearance with the thickness gauge to C 264
confirm that the specified value is secured. 2. In case that a lock-washer is used as a turning stopper of the lock nut. Prior to bending the tooth of the lock-washer into cutout of lock nut, measure again the clearance with the thickness gauge to confirm that the specified value is secured. 3. In case a hydraulic nut is used After removal of the hydraulic nut, mount the lock nut and measure the clearance again to confirm that the specified value remains constant prior to stopping the turning. 4. In case an oil injection pump is used Drop to zero the pressure of high pressure oil fed from the oil injection pump so that there is no pressure on bearing or sleeve fitted part. Next, measure the clearance with the thickness gauge to confirm that the specified value remains secured. Radial Internal Clearance and Clearance Reduction Amount of the Bearing to be Mounted • When radial internal clearance is CN clearance (normal clearance) Perform the clearance adjustment while aiming at a middle value between minimum and maximum clearance reduction amount. • W hen radial internal clearance is C3 or C4 clearance Perform the clearance adjustment aiming at the maximum clearance reduction amount. Internal Clearance Adjustment of Tapered-Bore Bearings Perform the adjustment by measuring the clearance reduction amount with the thickness gauge. 1. For measurement position and measured point, refer to Section 2.(Page C262) of this manual. 2. To mount a bearing on a tapered shaft, perform each time when the bearing is pushed in by the lock nut, end plate, end cap or hydraulic nut. 3. When using an adapter sleeve, perform each time when the bearing is pushed in by the lock nut or hydraulic nut. 4. When using a removable sleeve, perform each time when the removable sleeve is pushed in by the lock nut or hydraulic nut. When measuring the clearance during those operations, as the outer ring of bearing is hanging down from of rollers, turn the outer ring to right and left by one half to one full rotation while keeping the bearing in its correct posture. Position one randomly chosen roller from each row of rollers to the exact bottom position. Then, insert the thickness gauge to an appropriate place depending on size of the outer ring outside diameter to measure the internal clearance. For the clearance adjustment, the measured value of each clearance measurement shall be recorded.

Remarks 1. The bearings denoted by an asterisk (*) are NSKHPSTM bearings and an oil groove and holes are standard for them. 2. When making a selection of the recommended fit (Tolerance of shaft) on Page A164, in case of NSKHPSTM bearings, the conditions are different. The segmentations are: Light Loads(≦0.05Cr); Normal Loads(0.05 to 0.10Cr); and Heavy Loads(>0.10Cr). 3. For the dimensions od adapters and withdrawal sleeves, refer to Pages C354 – C355, and C360 – C361.

■THRUST BALL BEARINGS DESIGN, TYPES, AND FEATURES
MINIMUM AXIAL LOAD
THRUST BALL BEARINGS
Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. The series of thrust ball bearings available are shown in Table 1. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used as shown in Table 2. The cages in DoubleDirection Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series. The basic load ratings listed in the bearing tables are based on the standard cage type shown in Table 2. If the type of cage is different for bearings with the same number, the number of balls may vary, in such a case, the load rating will differ from the one listed in the bearing tables.
Table1 S eries of Thrust Ball Bearings
It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways. For more details, please refer to Page A198.

■THRUST CYLINDRICAL ROLLER BEARINGS DESIGN, TYPES, AND FEATURES THRUST CYLINDRICAL ROLLER BEARINGS
These are thrust bearings containing cylindrical rollers. They can sustain only axial loads, but they are suitable for heavy loads and have high axial rigidity. The cages are machined brass.
MINIMUM AXIAL LOAD It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways. For more details, please refer to Page A198.
TOLERANCES AND RUNNING ACCURACY THRUST CYLINDRICAL ROLLER BEARINGS ��������������������������������������������������������� According to Table 7.6 (Pages A140 to A142)

■THRUST TAPERED ROLLER BEARINGS DESIGN, TYPES, AND FEATURES THRUST TAPERED ROLLER BEARINGS
These are thrust bearings containing tapered rollers. TT-type bearings, which have a rib on the housing washer, can accurately guide the shaft in the radial direction. TTF-type bearings, which have no rib on the housing washer, can tolerate some eccentricity during operation.

TOLERANCES AND RUNNING ACCURACY THRUST TAPERED ROLLER BEARINGS������������������������������� Table 7.7 (Page A144)
RECOMMENDED FITS
THRUST TAPERED ROLLER BEARINGS������������������������������� Table 8.4 (Page A164) Table 8.6 (Page A165)
For inch design tapered roller thrust bearings, please contact NSK.
MINIMUM AXIAL LOAD It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways. For more details, please contact NSK.
USAGE EXAMPLE Typical structure of Heavy Duty Extruder is shown in Figure 2. Figure 2 Thrust Tapered Roller Bearing in Heavy Duty Extruder

■THRUST SPHERICAL ROLLER BEARINGS DESIGN, TYPES, AND FEATURES THRUST SPHERICAL ROLLER BEARINGS
These are thrust bearings containing convex rollers. They have a selfaligning capability and are free of any influence of mounting error or shaft deflection. Besides the original type, the E type with pressed cages for high load capacity is also available. Their bearing numbers are suffixed by E. For horizontal shaft or high speed application, machined brass cages are recommended. For details, contact NSK. Since there are several places where lubrication is difficult, such as the area between the roller heads and inner ring rib, the sliding surfaces between cage and guide sleeve, etc., oil lubrication should be used even at low speed. The cages in the original type are machined brass.

RECOMMENDED FITS
DIMENSIONS RELATED TO MOUNTING The dimensions related to mounting of thrust spherical roller bearings are listed in the Bearing Table. If the bearing load is heavy, it is necessary to design the shaft shoulder with ample strength in order to provide sufficient support for the shaft washer.
PERMISSIBLE MISALIGNMENT The permissible misalignment of thrust spherical roller bearings varies depending on the size, but it is approximately 0.018 to 0.036 radian (1° to 2°) with average loads.
MINIMUM AXIAL LOAD It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways. For more details, please refer to Page A198.

■PLUMMER BLOCKS
14. PLUMMER BLOCKS DESIGN, TYPES AND FEATURES There are numerous types and sizes of plummer blocks.
SN 5 SN 6 SN 30 SN 31 SN 2 SN 3 SN 2C SN 3C
These are the most common type. Models SN30 and SN31 are for medium loads. For types SN2C and SN3C, the bore diameters on the two sides are different.
SN 5B SN 6B SN 30B SN 31B SN 2B SN 3B SN 2BC SN 3BC
These have the same dimensions as those of types SN5 and SN6. To increase the bearing box strength, no material is removed from the top or bottom of the base, so mounting holes can be drilled anywhere.
Dustproof plummer blocks have a combination of oil seals, labyrinth seals, and oil groove seals, therefore, they are suitable for environments with much dust and other foreign matter.
SD 30S SD 31S SD 5 SD 6 SD 2 SD 3 SD 2C SD 3C
These are large and made for heavy loads. The standard ones have double seals and four mounting bolt holes. For types SD2C and SD3C, the bore diameters on the two sides are different.
SG 5
SD31TS SD32TS
V·C These are provided with labyrinth seals, so they are suitable for high speed applications.
C 344
Single-piece plummer blocks (integrated type roller bearing unit)have higher rigidity and precision than split type plummer blocks.
