Cross Roller Bearing

Crossed roller bearings are designed to offer the highest levels of rotational accuracy and rigidity while conserving space and saving material costs. The bearing features two sets of races and rollers brought together at right angles with alternate rollers facing in opposite directions. This allows two half-rows of rollers to fit into the space of one. The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
Crossed Roller Bearing CRBH series

CRBH type crossed roller bearing comes with an integrated inner/outer ring structure, which can be used for both inner-ring and outer-ring rotation. CRBH type are lightweight, compact bearings with the 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.
Crossed Roller Bearing RA series

RA cross roller bearing structure is designed with a split outer ring, an integral inner ring, and an ultra-thin size. This model is a compact type that reduces the thickness of the RB type inner and outer rings. The structure is the same as the RB type, and the outer ring is a 2-part structure that is fixed by rivets and becomes a whole. The overall structure of the inner ring is more suitable for situations with high inner ring rotation accuracy, with a stable rotation accuracy of up to micrometers. RA cross roller bearing takes up small space and can bear heavy loads.
Crossed Roller Bearing RB series

The RB shape features an outer ring divided into two parts and a single-piece inner ring structure, the basic format for a cross roller ring. Used in areas where inner ring rotation accuracy is required.crossed roller bearing stockist
