Bearing Reference Guide
Sealing: Retaining lubrication and preventing contamination from entering the bearing is critical in harsh environments. That is why Dodge has developed the premium QuadGuard® sealing system for maximum sealing effectiveness under these conditions. The seal includes two patented features unique to Dodge bearings; these features are standard on the ULTRA KLEEN product. The first is a triple-lip seal designed to maximize sealing and produce less drag than other multi-lip seals. The Dodge patented triple-lip design uses a mechanically retained seal with two contact points on the inner ring and one contact point riding against the flinger surface. Three points of contact maximize the ability of the seal to guard against contamination and to retain lubricants. The QuadGuard seal incorporates the QuadGuard industry’s first (and only) patented rubberized flinger. This flinger uses Maxlife Cage Sealing System molded rubber to provide additional protection from contaminants entering the bearing. The baffle design of the rubber on the external surface of the flinger enhances the removal of liquid as the flinger rotates. Grease chambers on the internal surface prevent lubricants from exiting the bearing during operation while allowing purging during re-lubrication. This superior design will increase service life in dirty environments thus leading to extended up-time for our customers. When used in conjunction with one another, the triple-lip seal and rubberized flinger create a sealing system that is ideal for demanding environments.
Retainer: The Maxlife® Cage is the product of extensive research and development in retainer technology and industry leading engineering. The cage features a two-piece design that creates a grease compartment around each of the rolling elements. These compartments allow balls to be constantly in contact with grease, so a good oil film will always exist to prevent wear and minimize friction and heat. The Maxlife cage reduces the relative motion between bearing components and grease which results in lower operating temperatures and extended life. The compartmental construction of the cage tends to hold in the grease and prevent it from being washed out in extremely wet or dirty conditions. This feature allows the bearing to be re-lubricated with less frequency than standard designs require, while extending bearing life.

Insert: The Dodge ULTRA KLEEN features inserts made of 100% stainless steel and includes set screws positioned at 65 degree angles to provide maximum locking force without compromising inner ring strength. The inserts each include a stainless anti-rotation pin to prevent insert rotation in the housing under load which may cause premature bearing failure. Stainless inserts eliminate the possibility of contamination due to chipping and flaking, commonly found in inserts which are coated with zinc or thin-dense chrome.

All Dodge E-Z KLEEN and ULTRA KLEEN bearings include a housing groove to accept a snap-on polymer end cover. These durable covers are easy to install and each is provided with a drain hole to prevent moisture from collecting inside the cover. The snap-on style of end cover incorporates an additional lip on the mounting surface for a rigid fit within the housing. This tight fit creates a better seal prevents movement of the cover during operation and highpressure cleaning. Dodge snap-on end covers provide positive sealing in wet environments and create safer working conditions by enclosing rotating shafts.

L10 Hours Life-the life which may be expected for at least 90% of a given group of bearings operating under identical conditions. Heavy Service-For heavy shock loads, frequent shock loads or severe vibrations, add up to 50% (according to severity of conditions) to the Equivalent Radial Load to obtain a Modified Equivalent Radial Load. Consult Application Engineering for additional selection assistance. A maximum thrust load value of C/10 is recommended as a guide for general applications and will give adequate L10 life. If the thrust load exceeds this limit, it is advisable to use auxiliary thrust carrying devices, such as a shaft shoulder, snap ring, or a thrust collar. Where substantial radial load pulls the housing away from the mounting base, both the hold-down bolts and housing must be of adequate strength. Auxiliary load carrying devices, such as shear bars, are advisable for side or end-loading of pillow blocks and radial loads for flange units. To determine the L10 hours life for loads and RPMs not listed use the following equation: 3

P = XFR + YFA Where: P = Equivalent Radial Load, lbs. FR= Radial load, lbs. FA= Thrust load, lbs. e = Thrust load to radial load factor (Table 1) X = Radial load factor (Table 1) Y = Thrust Factor (Table 1) C0= Basic static capacity (Selection Table) To find X and Y, first calculate FA/C0 to determine e. Calculate FA/FR and compare to e to determine the X and Y factors to use from Table 1. Substitute all known values into the Equivalent Radial Load equation. The Equivalent Radial Load (P) thus determined can be used in the L10 life formula or compared to the allowable Equivalent Radial Load rating desired in the expanded rating chart to select a bearing (Selection Table).

Bearing Reference Guide ULTRA KLEEN E-Z KLEEN
When the load on a ball bearing is solely a radial load with no thrust (axial) load, the Equivalent Radial Load (P) is equal to the actual radial load. However, when a thrust (axial) load is applied, the radial and thrust loads applied must be converted into an Equivalent Radial Load. Use X (radial factor) and Y (thrust factor) from Table 1 to convert the actual applied thrust and radial loads to an Equivalent Radial Load which has the same effect on the life of a bearing as a radial load of this magnitude.
Extreme Duty
Select a bearing from the Selection Table that has a radial load rating at the operating speed equal to or greater than the calculated Equivalent Radial Load for a desired L10 life. This simple method is all that is required for the majority of general applications and provides for occasional average shock loads.
Where: L10= Life, hours C = Dynamic Capacity, lbs. or N P = Equivalent Radial Load, lbs. or N n = Revolutions per minute
Setscrew Ball Bearing
DODGE ULTRA KLEEN mounted ball bearings are primarily designed for radial loading. However, they have the capacity to carry thrust loads and combined radial/ thrust loads. The maximum recommended load which can be applied is limited by various components in the system, such as bearing, housing, shaft attachments, speed and life requirements as listed in this catalog and the instruction manual that accompanies each bearing. DODGE ULTRA KLEEN ball bearings have been applied successfully when these limits have been exceeded under controlled operating conditions. Contact DODGE Engineering for applications which exceed these recommendations.

Lubrication- DODGE Ball Bearings are lubricated at the factory and are ready to run. The bearings are initially lubricated with an aluminum complex based, H1 Food Grade grease and should be relubricated with the same or some equivalent. For high speeds, high loads, extreme temperatures and other abnormal operating conditions, special greases may be required. Contact DODGE Application Engineering for recommendations on these types of applications. Misalignment - DODGE Ball Bearings are designed to allow a maximum of ±2º static misalignment. These bearings are not suitable for dynamic misalignment. To ensure good alignment, mounting surfaces must be checked for flatness and must lie in the same plane. When tightening base bolts, each bolt should be alternately tightening in incremental torque values until full torque is achieved to prevent the angular shifting of the pillow block that occurs when one bolt is tightened to its full torque. Shimming may be required to minimize misalignment.

Lubrication
High Speed Operation - In the higher speed ranges, too much grease will cause over-heating. The amount of grease that the bearing will take for a particular high speed application can only be determined by experience. If excess grease in the bearing causes overheating, it will be necessary to remove grease fitting to permit excess grease to escape. The bearing has been greased at the factory and is ready to run. When establishing a relubrication schedule, note that a small amount of grease at frequent intervals is preferable to a large amount at infrequent intervals.
