cross roller bearing

Crossed roller bearing is a special type bearing with split inner ring and rotating outer ring.

Description
Inquiry

Crossed roller bearing is a special type bearing with split inner ring and rotating outer ring. Since the divided inner ring or outer ring is installed with rollers and cage, it is fixed with the cross roller ring to prevent separation from each other, so it is easy to install the cross roller ring. Since the rollers are arranged in a cross, only one set of cross roller rings can bear loads in all directions. Compared with the conventional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained. Moreover, due to its special structure, it is usually used as a joint bearing in industrial robots.

Applications of crossed roller bearing:

•Industrial robot arms, reducers

•Precision machines( turnable table)

•Rotation parts of Machine tools

•Medical equipments

• Measuring instruments

SNAIL BEARING CO.LTD can offer high quality crossed roller bearings including THK RA, THK RB, THK RE, THK RU series, IKO CRB, IKO CRBC, IKO CRBF, IKO CRBH, INA SX, INA XU, INA XSU series and more. Custom cross roller bearings are also acceptable.
