Documentation
Description
BE retaining rings are radially assembled external bowed E-clips and are part of Rotor Clip’s radial retaining ring family. Designed to compensate for accumulated tolerances on a shaft, the BE ring exerts a force or a preload on the retained parts for the specified range once snapped into the groove.
