robot arm 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. XSU type 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.
