XSU Crossed Roller Bearings

XSU type cross roller bearing (inner and outer ring integrated type) This series of models does not require fixed flanges and support seats because the mounting holes have been processed. In addition, due to the integrated inner and outer ring structure with a seat, installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained. It can be used for outer and inner ring rotation. Structural features: Cross roller bearings are cylindrical rollers arranged vertically on the 90-degree V-groove rolling surface through isolation blocks, so cross roller bearings 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 extremely thin form is close to the limit of small size, and has high rigidity, and the accuracy can reach P5, P4, and P2 levels. Therefore, it is suitable for the joints and rotating parts of industrial robots, the rotary table of machining centers, precision rotary tables, medical machines, calculators, military industry, IC manufacturing equipment and other equipment.
