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