The cylindrical rollers of the HRAU series of thin-walled cross roller bearings with equal cross-section are arranged crosswise on the V-shaped raceway, and the rollers are separated by spacers. This structure of cross-arranged rollers allows a single bearing to It can withstand various loads such as axial load, radial load and overturning moment. In addition, since the inner and outer rings are of integral structure, it can be used for both inner ring rotation and outer ring rotation.

Since the external dimensions are miniaturized to the maximum, and the bearing has high rigidity, rotation accuracy and composite load capacity, it is most suitable for joints or rotating parts of industrial robots, direct drive motors, medical equipment, measuring instruments, etc. .

The cylindrical rollers of the HRAU series of thin-walled cross roller bearings with equal cross-section are arranged crosswise on the top of the V-shaped roller, and the rollers are separated by spacers. This cross-arranged roller structure makes a single bearing It can withstand various loads such as axial load, radial load and overturning moment. In addition, since the inner and outer rings are of integral structure, it can be used for both inner ring rotation and outer ring rotation.

The difference between A-type angular contact ball bearings and C-type bearings is that A-type bearings have sufficient radial clearance and can form sufficient contact angles to bear axial loads. Due to its unidirectional load capacity, the bearing needs to be installed in symmetrical pairs with other bearings to set and guarantee the contact angle while minimizing its axial movement when subjected to alternating axial loads.

The difference between X-type four-point angular contact ball bearings and A and C-type bearings lies in the shape of the ball groove. The deep groove depth and four-point contact structure enable the bearing to withstand radial, axial loads and torque loads, similar to a pair of A-type bearings back-to-back combination.
