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

Since the outer dimensions are miniaturized to the maximum extent, and the bearings have high rigidity, rotational accuracy, and combined load-bearing capacity, they are most suitable for joints or rotating parts of industrial robots, direct drive motors, medical equipment, measuring instruments, etc.
