External Retaining Ring Views
These standard retaining rings are stamped when manufactured. Retaining Rings are internal, external, e-rings, and c-rings. Stamped retaining rings can be manufactured in stainless steel, steel, copper, and zinc plated varieties. They are used in bores, shafts for bearings, axles, cylinders, gearboxes, the possiblities are endless.
External retaining rings are designed to go over a shaft and snap into a grove exerting radial tension towards the ring center. In other words, external retaining rings squeeze to hold the component in place on the shaft. When looking for the right external retaining ring the shaft diameter measurement is important. The proper fit will be a great factor on the reliability and proper functionality of the external retainer ring. The maximum thrust load must also be considered. Our rings are typically made out of carbon steel (SAE 1060-1095), but we have made them out of stainless steel and beryllium copper (for rings that have to conduct electricity more efficiently).
We have 3 main classes of external retaining (snap) rings. They are the XAN family, commonly found in the heavy equipment industry and drive trains among other applications, the EN family of external retaining rings, which is notched to aid in assembly and disassembly and the XD family, used for external light duty applications.
