CRB, CRBC Series Crossed Roller Bearing

Brand LYHGB
Product origin LUOYANG
Delivery time 3-20DAYS
Supply capacity 10000SETS/MONTH

Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.
The structure of CRB is that the outer ring is a split type, the inner ring is a one-piece design, and a full complement roller bearing without a cage. It is suitable for parts that require high rotation accuracy of the inner ring, and the structure of CRBC is a full complement roller bearing with a cage.

CRB and CRBC series Crossed Roller Bearing

Structure

The structure of CRB is that the outer ring is a split type, the inner ring is a one-piece design, and a full complement roller bearing without a cage. It is suitable for parts that require high rotation accuracy of the inner ring, and the structure of CRBC is a full complement roller bearing with a cage.

Product Features

High precision: accuracy can reach P4, P2 level;

High rigidity: high internal precision of the bearing, uniform load distribution, the series of bearings are preloaded;

High load: can withstand axial load, radial load, overturning load.

Small size: the bearing wall is thin, small size, can save space for the host.

Scope of application: It is widely used in precision rotary table, robot rotary joint, medical equipment, measuring instruments and so on.
