Retaining Rings

Also known as snap rings, retaining rings provide a removable shoulder to locate, retain, or lock components on shafts or in bores and housings. They are usually made of spring steel and have high shear strength and impact capacity. These rings can also be used to take up end play caused by accumulated tolerances or wear in the parts being retained. Three categories of rings are stamped, bent-wire, and spiral-wound retaining rings.
