The integrated design of the unit’s inner and outer rings, with mounting holes on both rings, eliminates the need for a special flange or housing and enables easy installation. Mounting has virtually no effect on performance, which ensures stable, accurate rotation and torque. Can be used for both outer and inner ring rotation.
