With the Cross-Roller Ring, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90° V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of theinner and outer rings, it is optimal for applications such as joints and swiveling units of industrialrobots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables,medical equipment, measuring instruments and IC manufacturing machines.

 Model RU (Integrated Inner/Outer Ring Type) 

The integrated design of the unit's inner andouter rings, with mounting holes on both rings, eliminates the need for a special flange or housing and enables easy installation. Mounting hasvirtually no effect on performance, which ensures stable, accurate rotation and torque.Can be used for both outer and inner ring rotation.
