Documentation
Description
RE retaining rings are radially assembled external reinforced E-clips and are part of Rotor Clip’s radial retaining ring line. The RE ring is a reinforced version of the standard E ring designed to accommodate higher thrust loadings and RPM. These rings function in the same groove as regular E rings, allowing for a transition between the two without the need for re-engineering the application.
