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.
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.

Product Features
Cross tapered roller bearing contains two sets of races and rollers brought together at high angles with alternate rollers facing in opposite directions. The height of cross section is similar to single-row bearing for conserving space and saving bearing housing material. And the steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
Series Introduction
XU type (inner and outer ring body type) has been processed with mounting holes, so there is no need to fix flanges and support seats. 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.
