4 G99TE Preface A linear guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using recirculating rolling elements between the rail and the block, a linear guideway can achieve high precision linear motion. Compared to a traditional slide, the coefficient of friction for a linear guideway is only 1/5. Because of the restraint effect between the rails and the blocks, linear guideways can take up loads in both the up/down and the left/right directions. With these features, linear guideways can greatly enhance moving accuracy, especially, when accompanied with precise ball screws. 1. General Information 1-1 Advantages and Features of Linear Guideways (1) High positional accuracy When a load is driven by a linear motion guideway, the frictional contact between the load and the bed desk is rolling contact. The coefficient of friction is only 1/5 of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving. (2) Long life with high motion accuracy With a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear; therefore, machines can achieve a long life with highly accurate motion. (3) High speed motion is possible with a low driving force Because linear guideways have little friction resistance, only a small driving force is needed to move a load. This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts. (4) Equal loading capacity in all directions With this special design, these linear guideways can take loads in either the vertical or horizontal directions. Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more likely to become inaccurate when they are subjected to these loads. (5) Easy installation Installing a linear guideway is fairly easy. Grinding or milling the machine surface, following the recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion. (6) Easy lubrication With a traditional sliding system, insufficient lubrication causes wear on the contact surfaces. Also, it can be quite difficult to supply sufficient lubrication to the contact surfaces because finding an appropriate lubrication point is not very easy. With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centralized oil lubrication system by piping the lubrication oil to the piping joint. (7) Interchangeability Compared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. For high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.

6 G99TE Basic Load Ratings of Linear Guideways Basic Static Load (1) Static load rating (C) Localized permanent deformation will be caused between the raceway surface and the rolling elements when a linear guideway is subjected to an excessively large load or an impact load while either at rest or in motion. If the amount of this permanent deformation exceeds a certain limit, it becomes an obstacle to the smooth operation of the linear guideway. Generally, the definition of the basic static load rating is a static load of constant magnitude and direction resulting in a total permanent deformation of.1 times the diameter of the rolling element and the raceway at the contact point subjected to the largest stress. The value is described in the dimension tables for each linear guideway. A designer can select a suitable linear guideway by referring to these tables. The maximum static load applied to a linear guideway must not exceed the basic static load rating. (2) Static permissible moment (M) The static permissible moment refers to a moment in a given direction and magnitude when the largest stress of the rolling elements in an applied system equals the stress induced by the Static Load Rating. The static permissible moment in linear motion systems is defined for three directions: MR, MP and MY. M R M P M Y (3) Static safety factor This condition applys when the guideway system is static or under low speed motion. The static safety factor, which depends on environmental and operating conditions, must be taken into consideration. A larger safety factor is especially important for guideways subject to impact loads (See Table 1-1). The static load can be obtained by using Eq. 1.1 Table 1-1 Static Safety Factor Load Condition f SL, f SM (Min.) Normal Load 1.~3. With impacts/vibrations 3.~5. C f SL = M or fsm = P M Eq.1.1 fsl : Static safety factor for simple load fsm : Static safety factor for moment C : Static load rating (kn) M : Static permissible moment (kn mm) P : Calculated working load (kn) M : Calculated appling moment (kn mm) Basic Dynamic Load (1) Dynamic load rating (C) The basic dynamic load rating is an important factor used for calculation of service life of linear guideway. It is defined as the maximum load when the load that does not change in direction or magnitude and results in a nominal life of 5km of operation for a ball type linear guideway and 1km for a roller type linear guideway. The values for the basic dynamic load rating of each guideway are shown in dimension tables. They can be used to predict the service life for a selected linear guideway.

7 4 G99TE Linear Guideways General Information 1-4 Service Life of Linear Guideways Service Life When the raceway and the rolling elements of a linear guideway are continuously subjected to repeated stresses, the raceway surface shows fatigue. Flaking will eventually occur. This is called fatigue flaking. The life of a linear guideway is defined as the total distance traveled until fatigue flaking appears on the surface of the raceway or rolling elements Nominal Life (L) The service life varies greatly even when the linear motion guideways are manufactured in the same way or operated under the same motion conditions. For this reason, nominal life is used as the criteria for predicting the service life of a linear motion guideway. The nominal life is the total distance that 9% of a group of identical linear motion guideways, operated under identical conditions, can travel without flaking. When the basic dynamic rated load is applied to a linear motion guideway, the nominal life is 5km Calculation of Nominal Life The acting load will affect the nominal life of a linear guideway. Based on the selected basic dynamic rated load and the actual load. The nominal life of ball type and roller type linear guideway can be calculated by Eq.1.2 and Eq. 1.3 respectively. 3 3 C Ball type: C L= 5km= ( 31mile P ) ( ) Eq.1.2 P 1 ) L= C 3 C 3 Roller type: P 1km= ( ( ) 62mile P L : Nominal life C : Basic dynamic load rating P : Actual load 1 Eq.1.3 If the environmental factors are taken into consideration, the nominal life is influenced greatly by the motion conditions, the hardness of the raceway, and the temperature of the linear guideway. The relationship between these factors is expressed in Eq.1.4 and Eq Ball type: L= f h f t C f w P c L= f h f Roller type: t C f w P c 3 3 f h f t C ) 5km= f w w P c c f h f t C 3 ) 1km= ( ( ) ( ( ) f w P c 31mile 62mile Eq.1.4 Eq.1.5 L : Nominal life fh : Hardness factor C : Basic dynamic load rating ft : Temperature factor PC : Calculated load fw : Load factor

8 1-4-4 Factors of Normal Life Raceway hardness G99TE (1) Hardness factor ( f h ) In general, the raceway surface in contact with the rolling elements must have the hardness of HRC 58~62 to an appropriate depth. When the specified hardness is not obtained, the permissible load is reduced and the nominal life is decreased. In this situation, the basic dynamic load rating and the basic static load rating must be multiplied by the hardness factor for calculation. (2) Temperature factor ( f t ) Due to the temperature will affect the material of linear guide, therefore the permissible load will be reduced and the nominal service life will be decreased when over 1 o C. Therefore, the basic dynamic and static load rating must be multiplied by the temperature factor. As some accessories are plastic which can t resist high temperature, the working enviornment is recommended to be lower than 1 o C. Temperature (3) Load factor ( fw ) The loads acting on a linear guideway include the weight of slide, the inertia load at the times of start and stop, and the moment loads caused by overhanging. These load factors are especially difficult to estimate because of mechanical vibrations and impacts. Therefore, the load on a linear guideway should be divided by the empircal factor. Table 1-2 Load factor Loading Condition Service Speed f w No impacts & vibration V 15 m/min 1 ~ 1.2 Small impacts 15 m/min <V 6 m/min 1.2 ~ 1.5 Normal load 6m/min < V 12 m/min 1.5 ~ 2.

To obtain the correct load value, each load condition should be carefully considered.

The definition of the mean load is the load equal to the bearing fatigue load under the variable loading conditions. It can be calculated by using table 1-5.

11 8 G99TE Linear Guideways General Information Calculation for Bidirectional Equivalent Loads HIWIN linear guideways can accept loads in several directions simultaneously. To calculate the service life of the guideway when the loads appear in multiple directions, calculate the equivalent load (Pe ) by using the equations below. l HG/EG/WE/QH/QE/QW/RG/QR Series P e = P + s P l Eq.1.8 MG Series when P e = P +.5 P l P > s P l s Eq.1.9 when P l P e = P +.5 P s > P s l Eq Calculation Example for Service Life A suitable linear guideway should be selected based on the acting load. The service life is calculated from the ratio of the working load and the basic dynamic load rating.

Calculation for life L f L= h x f t x C 3 1 x 1x ( 3 x 5 = x5 =3,258 (km) f w x P c ) ( ) 2 x Friction As mentioned in the preface, a linear guideway allows a type of rolling motion, which is achieved by using balls or rollers. The coefficient of friction for a linear guideway can be as little as 1/5 of a traditional slide. Generally, the coefficient of friction of ball type linear guideway is about.4 and roller type is about.3. When a load is 1% or less than the basic static load rate, the most of the resistance comes from the grease viscosity and frictional resistance between balls. In contrast, if the load is more than the basic static load rating, the resistance will mainly come from the load.

13 1 G99TE Linear Guideways General Information 1-7 Lubrication Supplying insufficient lubrication to the guideway will greatly reduce the service life due to an increase in rolling friction. The lubricant provides the following functions; Reduces the rolling friction between the contact surfaces to avoid abrasion and surface burning of the guideway. Generates a lubricant film between the rolling surfaces and decreases fatigue. Anti-corrosion Grease Linear guideway must be lubricated with the lithium soap based grease before installation. After the linear guideway is installed, we recommend that the guideway be re-lubricated every 1 km. It is possible to carry out the lubrication through the grease nipple. Generally, grease is applied for speeds that do not exceed 6 m/min faster speeds will require high-viscosity oil as a lubricant. T= 1 1 hr V e 6 T : Feeding frequency of oil (hour) Ve : speed (m/min) Oil The recommended viscosity of oil is about 32~15cSt. The standard grease nipple may be replaced by an oil piping joint for oil lubrication. Since oil evaporates quicker than grease, the recommended oil feed rate is approximate.3cm 3 /hr. 1-8 Jointed Rail Eq.1.12 Jointed rail should be installed by following the arrow sign and ordinal number which is marked on the surface of each rail. For matched pair, jointed rails, the jointed positions should be staggered. This will avoid accuracy problems due to discrepancies between the 2 rails (see figure) Reference side Reference side Stagger the joint position when installing matched jointed rail.

14 G99TE Mounting Configurations Linear guideways have equal load ratings in the radial, reverse radial and lateral directions. The application depends on the machine requirements and load directions. Typical layouts for linear guideways are shown below: use of one rail and mounting reference side use of two rails(block movement) use of two rails(block fixed) use of two external rails use of two internal rails total surface fixed installation HGW type block with mounting holes in different directions.

23 2 G99TE Linear Guideways HG Series 2-1 HG Series - Heavy Load Ball Type Linear Guideway HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, HIWIN HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion Features of HG Series (1) Self-aligning capability By design, the circular-arc groove has contact points at 45 degrees. HG series can absorb most installation errors due to surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements and the shift of contact points. Self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation. (2) Interchangeability Because of precision dimensional control, the dimensional tolerance of HG series can be kept in a reasonable range, which means that any blocks and any rails in a specific series can be used together while maintaining dimensional tolerance. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail. (3) High rigidity in all four directions Because of the four-row design, the HG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. Furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway allowing large permissible loads and high rigidity Construction of HG Series Block Bolt cap End seal (Double seals and scraper) End cap Rail Grease nipple Bottom seal Ball Retainer Rolling circulation system: Block, Rail, End Cap and Retainer Lubrication system: Grease Nipple and Piping Joint Dust protection system: End seal, Bottom Seal, Bolt Cap, Double Seals and Scraper Model Number of HG Series HG series guideways can be classified into non-interchangeable and interchangeable types. The sizes are identical. The only difference between the two types is that the interchangeable type of blocks and rails can be freely exchanged, and their accuracy can reach up to P class. The model number of HG series contains the size, type, accuracy class, preload class, etc..

29 26 G99TE Linear Guideways HG Series Preload (1) Definition A preload can be applied to each guideway. Oversized balls are used. Generally, a linear motion guideway has a negative clearance between groove and balls in order to improve stiffness and maintain high precision. The figure shows the load is multiplied by the preload, the rigidity is doubled and the deflection is reduced by one half. The preload not larger than ZA would be recommended for the model size under HG2 to avoid an over-preload affecting the guideway s life.

45 42 G99TE Linear Guideways EG Series 2-2 EG Series - Low Profile Ball Type Linear Guideway Features of the EG Series Linear Guideway 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 make the EG series more suitable for high-speed, 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 Construction of EG Series Block Cap Rail End seal (Double seals and scraper) End cap Grease nipple Ball Retainer Bottom seal Rolling circulation system: Block, rail, end cap and retainer Lubrication system: Grease nipple and piping Joint Dust protection system: End seal, bottom seal, cap and scraper Model Number of EG Series EG series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these two types are the same as one another. The main difference is that the interchangeable type of blocks and rails can be freely exchanged and they can maintain P-class accuracy. Because of strict dimensional control, the interchangeable type linear guideways are a wise choice for customers when rails do not need to be matched for an axis. The model number of the EG series identifies the size, type, accuracy class, preload class, etc.

50 G99TE Preload (1) Definition A preload can be applied to each guideway. Generally, a linear motion guideway has a negative clearance between the groove and balls in order to improve stiffness and maintain high precision. The figure shows that adding a preload can improve stiffness of the linear guideway. A preload not greater than ZA would be recommended for model sizes smaller than EG2. This will avoid an over-loaded condition that would affect guideway life.

93 9 G99TE Linear Guideways QH Series 2-6 QH Series Quiet Linear Guideway, with SynchMotion TM Technology The development of HIWIN-QH linear guideway is based on a four-row circular-arc contact. The HIWIN-QH series linear guideway with SynchMotion TM Technology offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the HIWIN-QH linear guideway has broad industrial applicability. In the hightech industry where high speed, low noise, and reduced dust generation is required, the HIWIN-QH series is interchangeable with the HIWIN-HG series Features (1) Low Noise Design With SynchMotion TM technology, rolling elements are interposed between the partitions of SynchMotion TM to provide impoved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced. 8 7 HG25 no grease QH25 no grease 5dB HG25 no grease QH25 no grease db(a) 6 db(a) mm/s khz (2) Self-Lubricant Design The partition is a grouping of hollow ring-like structures formed with a through hole to facilitate circulation of the lubricant. Because of the special lubrication path design, the lubricant of the partition storage space can be refilled. Therefore, the frequency of lubricant refilling can be decreased. The QH-series linear guideway is pre-lubricated. Performance testing at a.2c (basic dynamic load) shows that after running 4,km no damage was apparent to either the rolling elements or the raceway.

When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QH linear guideway, with SynchMotion TM technology prevents this condition. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to prevent contact with one another thus keeping the element's kinetic energy extremely stable in order to effectively reduce fluctuations in rolling resistance. Force(N) SynchMotion Type Conventional Type Time(.5sec) (4) High Speed Performance The Hiwin-QH series offers excellent high-speed performance due to the partitions of the SynchMotion TM structure. They are employed to separate the adjacent balls thereby resulting in low rolling traction and the metallic friction between adjacent balls is eliminated. Block Rail

The sizes are identical. The main difference is that the interchangeable blocks and rails can be freely exchanged. Because of dimensional control, the interchangeable type linear guideway is a perfect choice for the client when rails do not need to be paired for an axis. And since the QH and HG share the identical rails, the customer does not need to redesign when choosing the QH series. Therefore the HIWIN-QH linear guideway has increased applicability.

119 116 G99TE Linear Guideways QW Series 2-8 QW Series - Wide Rail Linear Guideway, with SynchMotion TM Technology The HIWIN QW series linear guideway with SynchMotion TM Technology possesses all the advantages of the WE series, which features high moment rigidity and is suitable for single rail or space saving applications. With the SynchMotion TM technology it also provides quieter and smoother movement, superior lubrication, and longer service life Construction Block End Cap Rail End Seal Grease Nipple Retainer Ball Bottom Seal The SynchMotion TM Model Number of QW Series HIWIN-QW series guideway can be classified into non-interchangeable and interchangeable types. The sizes are identical. The main difference is that the interchangeable blocks and rails can be freely exchanged. Because of dimensional control, the interchangeable type linear guideway is a perfect choice for the client when rails do not need to be paired for an axis. And since the QW and WE share the identical rails, the customer does not need to redesign when choosing the QW series. Therefore the HIWIN-QW linear guideway has increased applicability.

132 G99TE RG Series High Rigidity Roller Type Linear Guideway Advantages and features The new RG series from Hiwin features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The RG series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.the RG series linear guideway offers high performance for high-precision manufacturing and achieving longer service life. (1) Optimal design FEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion. (2) Super high rigidity The RG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller guideway features higher load capacity and greater rigidity. The figure shows the rigidity of a roller and a ball with equal volume. Deformation of Diameter (µm) Lateral Load(kN) (3) Super high load capacity With the four rows of rollers arranged at a contact angle of 45-degrees, the RG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The RG series has a higher load capacity in a smaller size than conventional, ball-type linear guideways. (4) Operating life increased Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore, stress concentration was reduced siginificantly and the RG series offers longer running life. The nominal life of RG series can be calculated by using Eq.

134 G99TE Model Number of RG series RG series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these two types are the same as one another. The main difference is that the interchangeable type of blocks and rails can be freely exchanged and they can maintain P-class accuracy. Because of strict dimensional control, the interchangeable type linear guideways are a wise choice for customers when rails do not need to be matched for an axis. The model number of the RG series identifies the size, type, accuracy class, preload class, etc. (1) Non-interchangeable type RG Series Block Type W : Flange Type H : Square Type Model size 15,2,25, 3, 35, 45, 55, 65 Load Type C : Heavy Load H : Super Heavy Load Block Mounting A : Mounting From Top C : Top or Bottom E: Special Block None: Standard Block No. of Blocks per Rail (2) Interchangeable type Model Number of RG Block RG Series Block Type W : Flange Type H : Square Type Model size 15,2,25, 3, 35, 45, 55, 65 Load Type C : Heavy Load H : Super Heavy Load RG W 35 C C E 2 R 164 E ZA P II + KK/E2/RC Model Number of RG Rail RG Series Interchangeable Rail Model size 15,2,25, 3, 35, 45, 55, 65 Rail Mounting Type R : Mounting From Top T : Bottom RG W 25 C A E ZA P + ZZ/E2 E: Special Rail None: Standard Rail Rail Length (mm) Rail Mounting Type R : Mounting From Top T : Bottom Note: 1.

151 148 G99TE Linear Guideways QR Series 2-1 QR series - Quiet Roller Type Linear Guideway HIWIN-QR series offers super high rigidity and very high load capacities. The HIWIN-QR series with SynchMotion TM Technology offers low friction, smooth movement, quieter operation and longer running life. In the industry where high accuracy, low noise and high rigidity is required, the QR series is interchangeable with the RG series Advantages and features (1) super high load capacity in linear guideway, with the four rows of rollers arranged at a contact angle of 45-degrees, the QR series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The QR series has a higher load capacity in a smaller size than conventional, ball-type linear guideways (2) Low Noise Design With SynchMotion TM technology, rolling elements are interposed between the partitions of SynchMotion TM to provide improved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced. db(a) dB RG2 Q R2 Noise Test Speed (mm/s) (3) smooth Movement In standard linear guideways, rolling elements on the load side of the guide block begin rolling and push their way through the raceway. When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QR linear guideway, with SynchMotion TM technology prevents this condition..75 SynchMotion Type Conventional Type Frictional force(kgf) Moving distance (mm) (4) The QR series is a type of linear guideway that uses rollers as the rolling elements. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.

153 15 G99TE Linear Guideways QR Series Model Number of QR series QR series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these two types are the same as one another. The main difference is that the interchangeable type of blocks and rails can be freely exchanged and they can maintain p-class accuracy. Because of strict dimensional control, the interchangeable type linear guideways are a wise choice for customers when rails do not need to be matched for an axis. The model number of the QR series identifies the size, type, accuracy class, preload class, etc. (1) Non-interchangeable type QR Series Block Type W : Flange Type H : Square Type Model size 2, 25, 3, 35, 45 Load Type C : Heavy Load H : Super Heavy Load Block Mounting A : Mounting From Top C : Top or Bottom E: Special Block None: Standard Block No. of Blocks per Rail (2) Interchangeable type Model Number of RG Block QR Series Block Type W : Flange Type H : Square Type Model size 2, 25, 3, 35, 45 Load Type C : Heavy Load H : Super Heavy Load QR W 35 C C E 2 R 164 E ZA P II + KK/E2/RC QR W 25 C A E ZA P + ZZ/E2 Model Number of QR Rail (QR and RG share the identical rails) QR/RG Series Interchangeable Rail Model size 2, 25, 3, 35, 45 Rail Mounting Type R : Mounting From Top T : Bottom Rail Mounting Type R : Mounting From Top T : Bottom Note: 1.

188 G99TE RC Type - Reinforced Cap The RC Reinforced Cap consists of a piece of hard plastic and a piece of an elastic O-ring. The hard plastic is made of synthetic resin which is characterized by oil resistance and abrasion resistance; the O-ring is made of rubber which is characterized by oil resistance and elasticity. The structure is shown on the illustration to the right. Hard plastic Elastic O-Ring Features of the Reinforced Cap (1) Absorb the machining error The elastic O-ring can eliminate some of the machining error caused during the creation of the mounting holes by maintaining the tight fit between the cap and the mounting hole. (2) Vibration and shock resistance The elastic O-ring can prevent the cap from loosening by absorbing the vibrations caused by external forces acting on the guideways. (3) High performance dust protection The Reinforced Cap is designed with an elastic O-ring to contact the mounting hole perfectly by eliminating the clearance between the cap and the mounting hole resulting in excellent dust protection. (4) Service life prolongation The service life of the guideway increases due to the smoothness of the rail surface after installation of the Reinforced Cap preventing any damage to the end seals during operation Specification (1) Non-interchangeable type - Add /RC after the specification of the linear guideway Ex.
