Description
MC retaining rings are radially assembled external ANSI metric circlips and are part of Rotor Clip’s radial retaining ring line. Named for their characteristic "C" shape, these crescent-style rings feature a shallow radial width. This design is effective for low clearance applications where radial installation is preferred.
