2 Structure and Features Models have especially high rigidity and load carrying capacity among the Caged Ball Guide series. In addition, these models maintain the Guide performance and achieve high reliability through the strengthening of the dust proof performance with a broad range of options that take into account the service environments of machine tools, etc. * Since models have very high rigidity, their structures are easily affected by the misalignment of the mounting surface and the installation error. If affected by these factors, their service life may be shortened or their motion may be disrupted. When considering using these models, contact THK. [Super Heavy Load, Increased Damping] The raceway of models adopts a circular-arc deep groove with a curvature approximate to the ball diameter. Since the ball contact area increases as the applied load increases, a large load carrying capacity is achieved and damping is also improved. Guide [Increased Dust-proof Performance] The foreign material removal function is improved with a newly developed protector to strengthen the dust-proof performance. In addition, use of a side scraper reduces the entrance of foreign material into the, thus maintaining the Guide performance for a long period even in adverse environments. [High Rigidity] Models achieve the highest rigidity among the Caged Ball Guide series. Both the radial type SVR and the 4-way equal load type SVS are available for the same size. Depending on the intended use, you can select either type. [Wide Array of Options] Various options are available, including end seal, inner seal, side seal, Laminated Contact Scraper LaCS, protector, side scraper and Cap GC, to respond to diversifi ed service environments.

[Models Contamination Protection Performance Evaluation] Models maintain their performance under severe conditions with fi ne particles or liquid contamination.

4 Types and Features Models SVR-R/SVS-R Specification Table/ With this type, the has a smaller width (W) and tapped holes. Used in places where the space for table width is limited. Guide Models SVR-LR/SVS-LR Specification Table/ The has the same cross-sectional shape as models -R, but has a longer overall length (L) and a greater rated load. Models SVR-C/SVS-C Specification Table/ The flange of the has tapped holes. Can be mounted from the top or the bottom. Can also be used in places where the table cannot have through holes for mounting bolts.

19 Standard Length and Maximum Length of the Rail Table1 shows the standard lengths and the maximum lengths of model variations. If the maximum length of the desired rail exceeds them, jointed rails will be used. Contact THK for details. For the G dimension when a special length is required, we recommend selecting the corresponding G value from the table. The longer the G dimension is, the less stable the G area may become after installation, thus causing an adverse impact to accuracy. G F F G L0 Table1 Standard Length and Maximum Length of the Rail for Models Unit: mm rail standard length (L O ) Standard pitch F G Max length Note1) The maximum length varies with accuracy grades. Contact THK for details. Note2) If jointed rails are not allowed and a greater length than the maximum values above is required, contact THK.
