RBU
The integrated inner/outer ring structure improves component rigidity over the RB, which has a split outer ring. This mitigates the impact of the housing’s accuracy and rigidity, providing stable performance.

Structure and Features
Because the RBU features cylindrical rollers that are arranged orthogonally between spacer cages inside a 90° V-shaped raceway, a single bearing can handle radial, axial, and moment loads in all directions. In addition, it can be used for both inner-ring and outer-ring rotation because neither the inner nor outer ring has a split structure.
