BRS High Precision Cross Roller Bearing IKO CRB series(with separators)

CRB Series bearing belongs to high precision cross roller bearings. Its cylindrical rollers are placed in a 90°V groove, with each roller arranged in cross-shape with the adjacent one, and separated from each other by a space retainer. CRB crossed roller bearings’ outer ring is designed to be separable, and fixed by screw.

CRB Series Crossed Roller Bearing Features

1. Sustain radial, axial and moment loads

2. Make the best use of space

3. Stable Rotation and high rigidity & running accuracy supplied with normal clearance, little clearance or Even under a pre-load.

Applications

CRB series cross roller bearings are specially suitable for the applications where space is limited, while high rigidity and high rotation accuracy are required. 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.
