Structure of Crossed Roller Bearings

The structure of the crossed cylindrical roller bearing is divided into the outer ring split and the inner ring as a whole; the outer ring as a whole, the inner ring split and the inner and outer rings are all three forms. The rolling elements are cylindrical rollers, which are vertically arranged at 90°. In the V-shaped raceway, the rollers are separated by spacers. This structure enables a single bearing to withstand loads in various aspects such as axial load, radial load and overturning moment. At the same time, due to the maximum miniaturization of the external dimensions, and the high rigidity and rotation accuracy of the bearing, as well as the composite bearing capacity, it is most suitable for the joint part or rotating part of industrial robots, the rotary table of the machining center, and the rotation of the manipulator. Department, precision rotary table, medical machine, measuring instrument and other occasions.
