Cross-Roller Ring Models RBU and RBUV

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.
Products with spacer retainers (Model RBU) have a low friction coefficient and demonstrate highly stable rotational torque. Full-Roller products (Model RBUV) are suited to low-speed rotary operations with higher loads, and they are also compatible with all-metal specifications.

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.
