Retaining Rings & Clips

A retaining ring is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed in a groove. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. E-Clip is a specific type of retaining ring that is named for its rounded "E" shape. E-Clip fasteners require a slotted shaft to hold items in place, such as bearings.
