Small crossed roller bearing,cylindrical rollers are arranged crosswise,with each roller perpendicular to the adjacent roller,separated from each other by a spacer ratainer.This design allows just one bearing to receive loads in all directions including,radial,axial and moment loads.

Cross roller bearing with high rigidity,high precesion,easily to install,The famous types are RA,RB,RU,RE,CRB,CRBC,CRBH series.

Since the Cross-roller Ring such as joints and swiveling units of industrial robots,swiveling tables of machining centers, precesion rotary tables,medical equipment,measuring instruments and IC manufacturing machines.
