Uniform cross-section thin-walled crossed roller bearings

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

Deep groove ball bearings: C-type deep groove ball bearings are single-row deep groove ball bearings with extra-deep grooves on the inner and outer rings (raceway groove depth = 25% of the ball diameter).

Angular contact ball bearings: A-type angular contact ball bearings differ from C-type bearings in that they have sufficient radial clearance to form a sufficient contact angle to withstand axial loads. Due to their unidirectional load capacity, the bearings need to be installed symmetrically with other bearings to set and ensure the contact angle, while minimizing their axial movement when subjected to alternating axial loads.

Four-point contact ball bearings: X-type four-point angular contact ball bearings differ from A- and C-type bearings in the shape of their ball grooves. The deep groove depth and four-point contact structure enable the bearings to withstand radial, axial and torque loads, similar to a back-to-back combination of a pair of A-type bearings.
