Cross-Roller Ring Series

Structure

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, 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 the inner and outer rings.

Features

Compact, Highly Rigid Swivel Bearings ,Achieving a Superb Rotation Accuracy

Applications

It is optimal for applications such as joints and swiveling units of industrial robots,

swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines

Cross roller Bearings with different Structure

Moldel RU series(intergrated inner ring and outer ring)

Since this series bearings with mounting holes already,they do not need flange or  housing.In addition,because it has anintergrated inner/outer ring structureand is equipped with washers,its performance is minimally affected by the mounting procedure,ensuring stable rotation accurancy and torque. 

This model can be used for both inner-ring rotation and outer ring is required.
