Use of a ball cage eliminates friction between balls, and achieves low noise, acceptable running sound, long-term maintenance-free operation, and superbly high speed response.

A ultra high rigidity Roller Guide that achieves low friction, smooth motion and long-term maintenance-free operation by using a roller cage.

A series of types are available from miniature types to large types for machine tools, from linear guides to curved guides that suit a wide-range of applications.

Models SPR/SPS realize super-low waving comparable to hydrostatic guides. In addition, the deformation of the ball is minimized to achieve ultra-high rigidity that surpasses even roller guides.
