High Precision Cross Roller Bearing IKO CRB series
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 spacer retainer. BRS High Precision Cross Roller Bearing IKO CRB
series‘ outer rings are designed to be separable, and fixed by screw.
High Precision Cross Roller Bearing IKO CRB series 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
IKO 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.
