Documentation
Description
ME retaining rings are radially assembled external ANSI metric circlips and are part of Rotor Clip’s radial retaining ring line. Named for their characteristic shape that resembles the letter E, these rings utilize three prongs to make contact with the bottom of the groove and provide a shoulder for the effective radial retention in assemblies.
