Features

Structure and Features

Models SVR/SVS have higher rigidity and load-bearing capacity than other models in the Caged-Ball LMGuide series. In addition, they maintain the performance of LM Guide and achieve high reliability by enhancing the dust-control performance with a wide range of options that take into account the service environments of machine tools and other machinery.

* Since models SVR/SVS 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 SVR/SVS 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.

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 LM block, thus maintaining the LM Guide performance for a long period even in adverse environments.

High Rigidity

Models SVR/SVS achieve the highest rigidity among the Caged Ball LM 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 diversified service environments.
