Linear Guideways Product Overview 1. Linear Guideways A linear guideway facilitates linear movement using ball bearings. Thanks to the use of ball bearings between the rail and the block, it is possible for a linear guideway to achieve extremely precise linear movement. In comparison with a conventional guide rail, the friction coefficient is only one fiftieth. Due to the restricted guidance of the block on the rail the linear guideway can carry loads in vertical and horizontal directions. 1.1 Product Overview

Linear Guideways HG/QH series 1.2 Linear Guideway Series HG and QH 1.2.1 Special characteristics of the linear guideway series HG and QH The HIWIN linear guideways of the HG series with four ball tracks are designed for high loads and rigidities. Due to the 45° arrangement of the ball tracks the HG series can equally take loads from all directions. Low displacement forces and a high efficiency are further features of the HG series. The ball retainers prevent the balls from falling out when the block is pulled off the rail during assembly.
The series QH with SynchMotion™ technology owns all the technical advantages of the standard models of series HG. In addition, because of the controlled movement of the balls in a defined distance to each other, they are characterized by an improved synchronous performance, a higher maximum speed, longer lubrication intervals and a lower noise level. Since the mounting dimensions of the QH blocks are identical to those of the HG blocks, they are also mounted on the HGR standard rail and therefore are very easy to replace
1.2.2 Structure of the HG/QH series ○ 4-row recirculation ball bearing guide ○ 45° contact angle of ball tracks ○ Ball retainers prevent the balls from falling out when the block is removed ○ Various sealing variants depending on the field of application ○ 6 options for connecting grease nipple or lubrication adapter ○ SynchMotion™ technology (QH series)

1.2.3 Advantages ○ Zero play ○ Interchangeable ○ High accuracy ○ High loading capacity in all loading directions ○ Low friction losses even with preload thanks to optimized ball tracks and 2-point contact
Additional advantages of QH series ○ Improved synchronous performance ○ Optimized for higher travel speeds ○ Extended lubrication intervals ○ Less running noise
1.2.4 Article numbers of the HG/QH series For HG/QH linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can be ordered separately and fitted by the customer. Their accuracy extends to class P.
Given their stringent dimensional accuracy check, the interchangeable models are a good choice for customers who do not use rails in pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the series include the dimensions, model, accuracy class, preload etc.

Elastic deformation
1.2.6.1 Definition Every rail type can be preloaded. Oversized balls are used for this purpose. Normally a linear guideway has negative clearance between track and balls to increase rigidity and precision. The curve shows that the rigidity doubles at higher preload. For rails below the nominal size of 20, a preload of no more than ZA is recommended to avoid the lifetime being shortened as a result of preload.

Note 1. The tolerance for E is +0.5 to –1 mm for standard rails and 0 to –0.3 mm for joints. 2. If the E1/2 dimensions are not indicated, the maximum possible number of mounting holes will be determined under consideration of E1/2 min. 3. The rails are shortened to the required length. If the E1/2 dimensions are not indicated, these will be carried out symmetrically.

1.2.10.3 Calculating the length of rails HIWIN offers rails in customized lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

Linear Guideways EG/QE series 1.3 Linear Guideway Series EG and QE 1.3.1 Special characteristics of the linear guideway series EG and QE The design of the EG series offers a low profile, high load capacity, and high rigidity. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length makes the EG series more suitable for highspeed automation machines and applications where space is limited. The retainer is designed to hold the balls in the block even when it is removed from the rail.
The series QE with SynchMotion™ technology owns all the technical advantages of the standard models of series EG. In addition, because of the controlled movement of the balls in a defined distance to each other, they are characterized by an improved synchronous performance, a higher maximum speed, longer lubrication intervals and a lower noise level. Since the mounting dimensions of the QE blocks are identical to those of the EG blocks, they are also mounted on the EGR standard rail and therefore are very easy to replace.
1.3.2 Structure of the EG/QE series ○ 4-row recirculation ball bearing guide ○ 45° contact angle of ball tracks ○ Ball retainers prevent the balls from falling out when the block is removed ○ Various sealing variants depending on the field of application ○ 6 options for connecting grease nipple or lubrication adapter ○ SynchMotion™ technology (QE series)

1.3.3 Advantages ○ Zero play ○ Interchangeable ○ High accuracy ○ High loading capacity in all loading directions ○ Low friction losses even with preload thanks to optimized ball tracks and 2-point contact
Additional advantages of QE series ○ Improved synchronous performance ○ Optimized for higher travel speeds ○ Extendes lubrication intervals ○ Less running noise
1.3.4 Article numbers of the EG/QE series For EG/QE linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can be ordered separately and fitted by the customer. Their accuracy extends to class P.
Given their stringent dimensional accuracy check, the interchangeable modules are a good choice for customers who do not use rails in pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the series include the dimensions, model, accuracy class, preload etc.

1.3.6 Preload Z0 Elastic deformation without preload
Elastic deformation
1.3.6.1 Definition Every rail type can be preloaded. Oversized balls are used for this purpose. Normally a linear guideway has negative clearance between track and balls to increase rigidity and precision. The curve shows that the rigidity doubles at higher preload. For rails below the nominal size of 20, a preload of no more than ZA is recommended to avoid the lifetime being shortened as a result of preload.

Note 1. The tolerance for E is +0.5 to –1 mm for standard rails and 0 to –0.3 mm for joints. 2. If the E1/2 dimensions are not indicated, the maximum possible number of mounting holes will be determined under consideration of E1/2 min. 3. The rails are shortened to the required length. If the E1/2 dimensions are not indicated, these will be carried out symmetrically.
1.3.10.4 Calculating the length of rails HIWIN offers rails in customised lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

Linear Guideways WE series 1.4 Linear Guideway Series WE 1.4.1 Properties of the linear guideway, series WE The HIWIN linear guideways of the WE series are based on proven HIWIN technology. Their large rail width and low installation height permit a compact design and high torque loading capacity. 1.4.2 Structure of the WE series ○ 4-row recirculation ball bearing guide ○ 45° contact angle ○ Ball retainers prevent the balls from falling out when the block is removed ○ Low installation height ○ Wide linear guideway for high torque loading capacity ○ Large mounting surface on block
Fig. Structure of the WE series
1.4.3 Advantages ○ Compact and low-cost design thanks to high torque loading capacity ○ High efficiency thanks to low friction losses
50 % wider than standard series
2-row mounting holes
○ The block’s large mounting surface supports the transfer of higher torques ○ The 45° arrangement of ball tracks permits high loading from all directions
○ Optimized geometry and high loading capacity thanks to FEM analysis of rail and block

1.4.4 Article numbers of the WE series For WE linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can therefore be ordered separately and fitted by the customer.
Their accuracy extends to class P. Given their stringent dimensional accuracy check, the interchangeable modules are a good choice for customers who do not use rails in pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the series include the dimensions, model, accuracy class, preload etc.

If the E1/2 dimensions are not indicated, these will be carried out symmetrically.
1.4.10.2 Calculating the length of rails HIWIN offers rails in customized lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

Linear Guideways MG series 1.5 Linear Guideway Series MG 1.5.1 Properties of the linear guideway, series MGN The HIWIN linear guideway of the MGN series is based on proven HIWIN technology. The Gothic arch contact design absorbs loads in all directions and is particularly rigid and precise. Given its compact and lightweight design, it is particularly suited to use in small devices. 1.5.2 Structure of the MGN series

1.5.3 Properties of the linear guideway, series MGW The HIWIN linear guideway of the MGW series is based on proven HIWIN technology. The Gothic arch contact design absorbs loads in all directions and is particularly rigid and precise. The MGW series has a wider rail than the MGN series so can absorb considerably higher load torques. 1.5.4 Structure of the MGW series

Linear Guideways MG series 1.5.6 Article numbers of the MG series For MGN and MGW linear guideways, a distinction is made between interchangeable and non-interchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can therefore be ordered separately and fitted by the customer.
Given their stringent dimensional accuracy check, the interchangeable modules are a good choice for customers who do not use rails in pairs on one axis. The article numbers include the dimensions, model, accuracy class, preload etc.

Linear Guideways MG series 1.5.11.3 Calculating the length of rails HIWIN offers rails in customized lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

1.5.12 Dust protection The blocks of the MG series are equipped on both sides with an end seal to protect against dirt as standard. Additional seals can be fitted underneath on the side of the block. Bottom seals can be ordered using the “+U” identifier in the article number. They are available as options for sizes 12 and 15. They cannot be fitted for sizes 7 and 9 due to the limited installation space H1. When fitting a bottom seal, the side mounting surface of the rail must not exceed H1.

1.6 Linear Guideway Series PM 1.6.1 Properties of the linear guideway, series PMN The HIWIN linear guideway of the PMN series is based on the proven MGN series. Thanks to the optimised ball return in the plastic duct, the synchronous performance and quiet running are improved and the weight is reduced by around 20 %. The Gothic race profile absorbs loads in all directions and is particularly rigid and precise. Given its compact and lightweight design, it is particularly suited to use in small devices. 1.6.2 Structure of the PMN series

1.6.3 Applications of the PM series The PM series was developed for use in restricted spaces, e.g. in the semiconductor industry, PCB population, medical technology, robot applications, measurement devices, office automation and other sectors needing miniature guides.

Linear Guideways PM series 1.6.4 Article numbers of the PM series For PM linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can therefore be ordered separately and fitted by the customer.
Given their stringent dimensional accuracy check, the interchangeable modules are a good choice for customers who do not use rails in pairs on one axis. The article numbers include the dimensions, model, accuracy class, preload etc.

1.6.8.2 Calculating the length of rails HIWIN offers rails in customised lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

Bottom seals can be ordered using the “+U” identifier in the article number. They are available as options for sizes 9 and 12. They cannot be fitted for size 5 due to the limited installation space H1. When fitting a bottom seal, the side mounting surface of the rail must not exceed H1.

Linear Guideways RG/QR series 1.7 Linear Guideway Series RG and QR 1.7.1 Properties of the linear guideways, series RG and QR The HIWIN linear guideways of the RG series use rollers rather than balls as rolling elements. The RG series provides extremely good rigidity and very good loading capacity. It is designed with a 45° contact angle. Its linear contact surface greatly reduces deformation from the loading produced and therefore ensures very good rigidity and loading capacity in all 4 loading directions. The linear guides of the RG series are therefore ideal for use in high-precision manufacturing.
The models of the QR series with SynchMotion™ technology offer all the positive properties of the standard series RG. Controlled movement of the rollers at a defined distance also results in improved synchronous performance, higher reliable travel speeds, extended lubrication intervals and less running noise. Since the installation dimensions of the QR blocks are identical to those of the RG blocks, they are also fitted on the RGR standard rail and can therefore be interchanged with ease.
1.7.2 Structure of the RG/QR series ○ 4-row recirculation roller bearing guide ○ 45° contact angle ○ Ball retainers prevent the rollers from falling out when the block is removed ○ Various sealing variants depending on the field of application ○ 6 options for connecting grease nipple and lubrication adapter ○ SynchMotion™ technology (QR series)
Fig. Structure of the RG series
1.7.3 Advantages ○ Zero play ○ Interchangeable ○ Very high load ratings ○ Very high rigidity ○ Low displacement forces even with high preload
1.7.4 Article numbers of the RG/QR series For RG/QR linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. The article numbers of the series include the dimensions, model, accuracy class, preload etc.

Note: 1. The tolerance for E is +0.5 to –1 mm for standard rails and 0 to –0.3 mm for joints. 2. If the E1/2 dimensions are not indicated, the maximum possible number of mounting holes will be determined under consideration of E1/2 min. 3. The rails are shortened to the required length. If the E1/2 dimensions are not indicated, these will be carried out symmetrically

Linear Guideways RG/QR series 1.7.10.3 Calculating the length of rails HIWIN offers rails in customized lengths. To prevent the risk of the end of the rail becoming unstable, the value E must not exceed half of the distance between the mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and E1/2 max so that the mounting hole does not rupture. n = Number of mounting holes

1.8.2 Sealing systems SS, ZZ, DD, KK The HIWIN end seals firstly prevent the ingress of foreign substances such as dust particles, chips or liquid into the block's ball tracks and secondly reduce the amount of lubricant lost. HIWIN provides various sealing systems for the various ambient condi-
tions of your application. The effectiveness of the end seal impacts directly on the lifetime of the linear guideway and should therefore be taken into account at the design stage and selected to suit the ambient conditions of your application.
SS (standard): End seal with bottom seal ○ For applications with little dirt and dust ○ Only minimal increase in displacement forces
ZZ: End seal with bottom seal and scraper ○ For applications associated with hot chips or sharp-edged particles of dirt ○ The scraper protects the end seal and prevents it from being damaged
DD: Double end seal with bottom seal ○ For applications associated with a lot of dirt and dust ○ The double end seal effectively prevents the ingress of dirt into the block
KK: Double end seal with bottom seal and scraper ○ For applications associated with a lot of dirt and dust and hot chips or sharp-edged particles of dirt ○ The scraper protects the end seals and prevents them from being damaged
Availability of sealing systems SS, ZZ, DD and KK: Sealing systems SS, ZZ, DD and KK are available for all series and sizes. The exceptions are the MG and PM series, for which only the standard sealing system SS is available.

Linear Guideways Accessories 1.8.3 Sealing systems SW and ZWX for optimum dust protection Sealing systems SW and ZWX allow HIWIN linear guideways to also be used in areas with very high levels of dirt. The sealing systems offer optimum protection against
the ingress of dirt, dust and liquid. The end seal is resistant to oils and greases and very resistant to wear.
Properties: ○ End seal with double sealing lip ○ Optimized bottom seal ○ Additional top seal ○ Optimized stainless steel scraper
Advantages: ○ Optimum dust protection ○ Lifetime extended ten-fold ○ Longer lubrication intervals ○ Lower maintenance costs
SW: End seal with double sealing lip, optimized bottom seal and additional top seal ○ Optimum dust protection ○ The additional top seal prevents the ingress of dirt via the top of the rail ○ The optimized bottom seal protects against the ingress of dirt on the rail flank
ZWX: End seal with double sealing lip, optimized bottom seal, additional top seal and optimized scraper ○ Optimum dust protection ○ The additional top seal prevents the ingress of dirt via the top of the rail ○ The optimized bottom seal protects against the ingress of dirt on the rail flank ○ The optimized scraper also protects against dirt particles > 0.2 mm in diameter and prevents damage to the end seal.
Dust test for sealing systems SW and ZWX Thorough dust tests have shown that the lifetime with sealing systems SW and ZWX is ten times longer than that with a standard seal in cases of high dust levels. Test conditions: ○ Sealed room in which MDF dust is swirled about ○ v = 1.3 m/s ○ Grease lubrication

2. Ballscrews Ballscrews consist of a ballscrew shaft, a ballscrew nut into which the balls are integrated and the ball recirculation system. HIWIN ballscrews are distinguished by their low-friction and precise running, require little drive torque and offer good rigidity with smooth operation. HIWIN ballscrews are available in rolled, peeled and ground versions, making them the optimum product for any application. HIWIN has at its disposal state-of-the-art production facilities, highly qualified engineers and qualityassured manufacturing and assembly and only uses high-grade materials to meet all your requirements. 2.1 Product Overview

Ballscrews Rolled Ballscrews 2.2 Rolled Ballscrews 2.2.1 Properties One of the benefits of rolled ballscrews is that feed systems equipped with them have less friction and are quieter than standard threads. HIWIN manufactures them using state-of-the-art rolling technologies where the processes of material selection, rolling, heat treatment, machining and assembly are very closely coordinated.
Rolled ballscrews from HIWIN can be flexibly used in virtually all areas of industry. Rolled ballscrew shafts with diameters of 8 mm to 63 mm are always kept in stock and can be supplied at short notice. They can be supplied with or without end machining. Complete bearing units combined with standardised shaft ends enable us to supply complete ballscrews.
2.2.2 Tolerance classes Table 2.2 shows the tolerance classes of rolled ballscrews. The lead accuracy is defined using the deviation from nominal path over any 300 mm section of the entire length.

Ballscrews Peeled Ballscrews 2.3 Peeled Ballscrews 2.3.1 Properties In terms of quality, peeled ballscrews from HIWIN fall between rolled and ground ballscrews and can therefore be used for numerous transport or positioning applications. On request, we are happy to produce a lead measurement report for them. A number of nut shapes are available for peeled ballscrews, as both single and double nuts.
Customised complete ballscrews can be produced with short lead times. Complete bearing units combined with standardised shaft ends minimise the amount of design work involved.
2.3.2 Tolerance classes Table 2.7 shows the tolerance classes of peeled ballscrews. The lead accuracy is defined using the deviation from nominal path over any 300 mm section of the entire length.

Ballscrews Peeled Ballscrews 2.3.9 Safety nut SEM The safety nut comprises a ball thread unit and safety unit. The safety nut basically works like a normal ballscrew nut. If the axial backlash is increased due to wear, ball failure or ball loss, the thread of the safety unit comes into contact with the ball thread. The nut cannot therefore break out. The normal function of the unit is guaranteed up to an axial backlash of 0.4 mm. Ball screw unit

Simply using a safety nut does not provide sufficient protection against a load being lowered unintentionally. The safety guidelines valid for the application must be observed. Other measures, such as monitoring the motor current and the driveline, should be in place.

2.3.10 Driven nut unit AME The threaded nut is mounted in an axial angular ball bearing ZKLF...2Z. The less stringent PE version is preferred. The bearing has defined preload using a precision groove nut from the HIR series. The bearing achieves a good resistance to tilting thanks to the O arrangement of the two rows of balls. Any axial and radial forces which arise are absorbed with ease. The thick-walled, dimensionally-stable outer bearing race is screwed directly onto the bearing block.

There is no need for an extra bearing bush or bearing cover. Circulating oil lubrication supplies the bearing with lubricant. The ballscrew nut is lubricated via a radial bore in the shaft. The less stringent axial angular ball bearing can only be lubricated axially. We are happy to develop the right unit for any application, taking due account of different installation circumstances. A wide range of realised applications provides the ideal basis for finding a solution to your problem.

Ballscrews Accessories 2.4 Accessories 2.4.1 Shaft ends and bearing configuration To reduce the amount of design work required, we provide standardised end machining processes and bearing units. We recommend the “B”, “E” and “F” bearing series for simple applications and low axial forces. They are suited to all tasks in applications where the ballscrew is not subject to stringent requirements. The SFA and SLA bearing units are suited to more challenging applications. The WBK series is available for heavy-duty applications.
When selecting the suitable bearing type, the permissible axial force of the fixed bearing must also be taken into account. Types of assembly The type of installation and mounting of the ballscrew shafts are decisive for rigidity, critical sped and buckling load. This must be given careful consideration when selecting the type of assembly.

Positioning Systems KK Linear axes 3. Positioning Systems 3.1 KK Linear axes 3.1.1 Product overview KK linear axes The HIWIN KK linear axes are compact positioning axes, which are supplied fully mounted with HIWIN servo motor and HIWIN servo drive. Alternatively, the KK linear axis can also be supplied with “motor-ready” mountings for connecting to customerspecific motors. High levels of accuracy and rigidity are achieved through a linear guideway in the steel profile with integrated ballscrew. The axis is available in different sizes and lengths and can be adapted to the relevant application requirements through additional options such as aluminium covers, bellow covers, limit switches and additional blocks. 3.1.2 Advantages of KK linear axes ○ Ready-to-install complete axis with HIWIN servo motor and HIWIN drive ○ Universal use ○ Compact design ○ Adaptable and robust ○ High precision and rigidity
