External Retaining Rings
 |
Secure components on a shaft with our go-to external retaining rings. Shaped in the most common style, these are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Open with retaining ring pliers, pass over the end of a shaft, then release them to spring into a groove.
Ring ID is measured with the ring uninstalled.
Beryllium Copper—Nonmagnetic rings that conduct electricity and have good corrosion and wear resistance. Do not use in direct contact with acetylene.

Secure components inside a housing or bore with our go-to internal retaining rings. Shaped in the most common style, these are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Squeeze with retaining ring pliers and release into a groove.
Ring OD is measured with the ring uninstalled.

Side-Mount External Retaining Rings
 |
When you can't access the ends of a shaft, install these rings anywhere along its length. Also known as E-Style rings, these grip the shaft with three contact points and a wide shoulder. Push into the groove with a side-mount retaining ring tool.
Ring OD is measured with the ring uninstalled.
