Bearings mainly play the role of supporting and reducing friction in machinery. For high-speed applications that simultaneously bear multi-directional loads such as radial load, axial load and moment load, crossed roller bearings are generally used.

The dimensions of the inner and outer rings of crossed roller bearings are minimized. In particular, the ultra-thin structure is close to the limit of small size and has high rigidity. Therefore, it is used in the joints or rotating parts of industrial robots and the rotating table of machining centers. , manipulator rotating parts, precision rotating tables, medical instruments, measuring instruments, IC manufacturing equipment, etc.

HRU type (integrated inner and outer rings, with mounting holes), because the outer ring and inner ring have mounting holes, no fixed flange and support seat are required during installation. In addition, since both the outer ring and the inner ring are integral structures, installation has almost no impact on performance, so stable rotation accuracy and torque can be obtained. Suitable for situations where the outer ring and inner ring rotate.

Type HRB (integrated inner ring, separate outer ring) This model is the basic type of crossed roller bearing. The outer ring is divided into two pieces, and the inner ring is an integral structure. It is most suitable for applications that require the rotation accuracy of the inner ring.

HRBH type (integrated inner and outer rings, ultra-thin), due to its ultra-thin design and no mounting holes in the outer and inner rings, the flange and support base are required for installation. In addition, since the outer ring and inner ring are both integral structures, installation has no impact on performance, so stable rotation accuracy and torque can be obtained. It is suitable for occasions where the outer ring and inner ring rotate but require miniaturization.

HRAU type (integrated inner and outer rings, ultra-thin), this model is a compact model that reduces the thickness of the HRB type inner and outer rings to the limit. It is most suitable for parts that require light weight and compact design, such as the rotating parts of robots and manipulators, and can Suitable for situations where the inner and outer rings rotate.

HSX type (integrated inner ring, separate outer ring, ultra-thin). Under the same shaft diameter, this type has a smaller cross-section size than the HRB type. Due to the ultra-thin design, the outer and inner rings are not installed. hole, the flange and the support base are required for installation, and are suitable for applications where the inner ring rotates.

XR/JXR type: The large cone angle and tapered geometric design make the overall effective span of the bearing larger, while also saving space and material costs. Therefore, crossed tapered roller bearings have higher anti-overturning moment capabilities, higher rotation accuracy and limit speed, and are ideal choices for bearings for machine tool turntables such as high-speed vertical lathes, vertical boring machines, and vertical grinders.
