This type (integral inner and outer rings, with mounting holes) does not require a fixed flange or support seat during installation because both the outer and inner rings have mounting holes. In addition, since both the outer and inner rings are integral structures, installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained, which is suitable for occasions where the outer and inner rings rotate.

HRU series cross roller bearings widely used on the robots base, and other precision rotating parts.
