cross roller cylindrical bearing

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.
