Super-Precision Cylindrical Roller Bearings

Super Precision Cylindrical Roller Bearings are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements.

This lineup of bearing includes a basic series that meets ISO standards and a specified series targeting machine tools.

A double-row cylindrical roller bearing series is available for applications requiring high rigidity. A single-row cylindrical roller bearing series is available for applications requiring high-speed performance.

A Robust™ series of high performance bearings is available for applications requiring both high-speed and high-rigidity performance.
