HRU type (inner and outer ring integral, with mounting holes), because the outer ring and inner ring have mounting holes, the installation does not need a fixed flange and support seat.In addition, because the outer and inner rings are integral, the installation has little effect on performance, so stable rotation accuracy and torque can be obtained.Suitable for outer and inner ring rotation.

HRB type (integral inner ring, separated outer ring) This model is the basic type of cross roller bearings.The outer ring is divided into two pieces, and the inner ring is an integral structure, which is most suitable for the occasions where the rotation accuracy of the inner ring is required.

HRBH type (inner and outer ring integral, ultra-thin), due to the use of ultra-thin design and outer ring and inner ring without mounting holes, installation requires flange and support seat fixed.In addition, because the outer ring and inner ring are integral structure, the installation has no effect on the performance, so it can obtain stable rotation accuracy and torque, suitable for outer ring and inner ring rotation but have the requirements of small size occasions.

HRAU type (integral inner and outer ring, ultra-thin), this is the HRB type inner and outer ring thickness reduced to the limit of the compact model, best suited for light weight, compact design, such as robot and manipulator rotation parts, and can be used in the inner and outer ring rotation applications

HSX type (integral inner ring, split outer ring, ultra-thin), in the case of the same shaft diameter, this type has a smaller section size than HRB type, because of the use of ultra-thin design, outer ring and inner ring without mounting holes, installation requires flange and support seat fixed, suitable for the application of inner ring rotation.

Cross tapered roller bearings:

XR/JXR type: the use of large cone Angle and conical geometry design is the overall effective span of the bearing is larger, colleagues can also save space, save material costs.Therefore, cross tapered roller bearings have higher anti-overturning torque capacity, higher rotation accuracy and limit speed, and are ideal choice for bearing for machine tool turntables such as high-speed vertical lathe, vertical boring machine and vertical grinding machine.
