Stainless Steel Retaining Ring

A stainless steel retaining ring is an open-type fastening element.

The ring secures parts and assembly components on a shaft or in a bore. It is often used to secure rolling bearings.

Installation is performed into specially prepared grooves, round recesses, or a channel. The operating principle is simple: the protruding part of the ring acts as a shoulder, holding the part in its installed position.

Applications

This fastening method allows parts to be quickly removed for repair and provides reliable retention. Stainless steel retaining rings are used in machine tool building, automotive manufacturing, instrument engineering, and other fields where mechanism components need to be securely fixed in place.

Features

The material is carbon or stainless steel with additives. The coating can be a chemical oxidizing with oiling, or the ring can be supplied without coating. The most common option is phosphating. Phosphating protects the product for 10–70 hours — for transport and initial installation.
