HRB series

This type (integral inner ring, split outer ring) is the basic type of cross cylindrical roller bearing. The outer ring is divided into two pieces, and the inner ring is an integral structure. It is more suitable for occasions requiring inner ring rotation accuracy.

HRBH series

This type has both integral inner and outer rings without mounting holes. A fixed flange and support seat are required for installation. The outer and inner rings are both integral structures, which can obtain stable rotation accuracy and torque. It is suitable for occasions where the outer and inner rings rotate but there is a requirement for miniaturization.

HRU series

This type (integral inner and outer rings, with mounting holes) does not require a fixed flange and support seat for 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. It is suitable for occasions where the outer and inner rings rotate.

HSX series

Under the same shaft journal, this type (split outer ring and integral inner ring) has a smaller cross-sectional size than the HRBH type. Due to the ultra-thin design, the outer and inner rings have no mounting holes, and a fixed flange and support seat are required for installation.

HRAU series

This model has an integral structure for both inner and outer rings, which can be used for inner ring rotation or outer ring rotation. As the outer dimensions are miniaturized to the maximum, and the bearing has high rigidity, rotation accuracy and composite load-bearing capacity, it is suitable for parts that require light weight and compact design, such as rotating parts of robots and manipulators, direct drive motors, medical equipment, measuring instruments and other fields.
