crossed roller 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. RU special type is a bearing with integrated inner- and outer ring. Since the inner and outer rings have been machined with mounting holes, there is no need to fix the flange and the support seat, which shortens the axial space distance and optimizes the use mechanism. In addition, due to the integrated inner and outer ring structure with seat, installation has little effect on performance, so stable transmission accuracy and torque can be obtained. Both inner and outer ring rotating mechanisms are suitable. Widely used in robot waist joints, welding multi-station rotary table, communication radar, precision measuring instruments, etc.

XU series crossed roller bearings (inner and outer ring body types) have been machined with mounting holes, so there is no need for a fixed flange and a support seat. In addition, due to the integrated inner and outer ring structure with seat, installation has little effect on performance, so stable rotation accuracy and torque can be obtained. Can be used for outer and inner ring rotation.
