The cylindrical rollers of RAU series are arranged crosswise on the V-railway, and the rollers are separated from each other by spacers. The structure of this crosswise arrangement of rollers makes the single bearing

can bear all kinds of loads such as axial load, radial load and tilting moment. In addition, since the inner and outer rings are of integral structure, they can be used for inner ring rotation and outer ring rotation.

Because of the maximum miniaturization of the external dimensions, the high rigidity, rotational accuracy of the extractor and the composite load capacity, it is most suitable for the joint or rotating part of industrial robots, direct drive motors, medical equipment, measuring instruments, etc.
