IKO CRB crossed roller bearing feature:

Crossed roller bearings are two-row cylindrical rollers that are vertically aligned with each other through a nylon spacer on a 90-degree V-shaped raceway. Therefore, the cross-roller bearing can withstand multiple loads such as radial load, axial load and moment load. . The size of the inner and outer rings is miniaturized, the extremely thin form is a small size close to the limit, and has high rigidity, and the DK crossed roller bearing accuracy can reach P2-P5.

CRB series crossed roller bearing (Separable Outer Ring,For Inner Ring Rotation)

CRB series crossed roller bearings:    CRB type: Without cage,Full complement rollers;    CRBC type: With Cage ;
The outer ring is split while the inner ring is integrated into the main body. It is being used in cases where a high rotational accuracy of the inner ring is required.

IKO CRB crossed roller bearing application:

It is suitable for cases where the space is limited, where the high rigidity and hig rotation accuracy is required. Mainly used in engineering machinery, machine tools, automobiles, metallurgy, mining, petroleum, machinery, electric power, railways and other industries.
