Crossed roller bearing(Integrated Inner/Outer Ring Type)The mounting holes of HXU series are provided, this model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. XU series can be used for both inner-ring rotation and outer-ring rotation.HXSU  sealed series Crossed Roller Bearings of high rigidity cross roller bearing inner and outer rings are with the overall structure, with high rigidity, and with mounting holes, no bearing flange and installation, to a large extent simplify the installation process, and does not affect the mounting accuracy, with high precision and high torque rotation, but also free to choose the inner or outer ring rotation mode in accordance with the accuracy requirements, with greater freedom of choice. It differs HRU is sealed structure using double-sided spring reed seal, and dimensions are more compact than HRU series, more suitable for small mounting space installed.
