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 Structure of the 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 Fig. Structure of the QR series Advantages Zero play Interchangeable Very high load ratings Very high rigidity Low displacement forces even with high preload Additional advantages of QR series Improved synchronous performance Optimized for higher travel speeds Extended lubrication intervals Less running noise Article numbers of the 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.

3 1.7.5 Block types HIWIN provides square and flange blocks for the linear guideways. Given their low height and large mounting surface, flange blocks are suited to large loads.

Overd rollers are used for this purpose. Normally a linear guideway has negative clearance between track and rollers to increase rigidity and precision. The linear guideways of the offer three standard preloads for various applications and conditions. Elastic deformation Z0 Elastic deformation without preload ZB Elastic deformation with high preload P = 0,07 C dyn 2,8 P Operating load Preload ID Table 1.90 Preload ID ID Preload Application ZO Light preload 0,02 0,04 C dyn Constant load direction, little impact, low precision required ZA Medium preload 0,07 0,09 C dyn High precision needed ZB High preload 0,12 0,14 C dyn Very high rigidity required, with vibration and impact

4 The diagram shows the relationship between rigidity, frictional resistance and nominal lifetime. For smaller models, a preload of no more than ZA is recommended to avoid the lifetime being shortened as a result of preload.

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

9 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 E 1/2 should be between E 1/2 min and E 1/2 max so that the mounting hole does not rupture. n = Number of mounting holes E 1 P L E 2 L: Total length of the rail n: Number of mounting holes P: Distance between two mounting holes E 1/2 : Distance from the middle of the last mounting hole to the end of the rail Tightening torques for mounting bolts Insufficient tightening of the mounting bolts strongly compromises the precision of the linear guideway. The following tightening torques are recommended for the relevant screw s.
