Crossed roller bearings are two rows of cylindrical rollers arranged perpendicularly and crosswise on a 90-degree V-shaped raceway through nylon spacers, so they can withstand multi-directional loads such as radial loads, axial loads, and moment loads. The size of the inner and outer rings is miniaturized, and the ultra-thin form is close to the ultimate small size, and has high rigidity. 

The precision of XU crossed roller bearings can reach P2 level. Therefore, it is suitable for the joint rotation part of industrial robots, the rotary table of machining centers, precision rotary tables, medical equipment, calculators, IC manufacturing devices and other equipment.
