RB Series Crossed Roller Bearing

RB standard type is a bearing with thinnest possible inner and outer rings because 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.

Description

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.

RB standard type is a bearing with thinnest possible inner and outer rings because the outer ring is split while the inner ring is integrated into the main body. The miniaturized design of thin-walled size is helpful for the light and thin design of related structures. The overall structure of the inner ring is more suitable for occasions with high rotation accuracy of the inner ring, and the stable rotation accuracy reaches microns; it is suitable for precision testing instruments, robot joints, and direct drive torque. Motors, high-precision turntables and other applications requiring high precision and high rigidity.
