Rotor Clip MC Rings

Ideal for low clearance applications where radial installation is preferred.

Rotor Clip ME Rings

Perhaps the most popular and widely used radial retaining ring is the “E” (so named because it is shaped like the letter “E”). Three prongs make contact with the bottom of the groove and provide a shoulder for effective retention of assemblies.

Rotor Clip MRE Rings

The MRE retaining ring is a reinforced version of the ME ring, which will accommodate higher thrust loadings and RPM. MRE rings function in the same size grooves as regular E rings, so that you can change from one to the other without re-engineering the application.
