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.

The extremely small cross-sectional area allows it to be used in lightweight, compact devices. The integrated inner/outer ring structure can be used for both inner and outer ring rotation. There is a 5 mm thin type and an RA interchangeable type.

The integrated design of the unit’s inner and outer rings, with mounting holes on both rings,eliminates the need for a special fl ange or housing and enables easy installation.
