Open these rings, pass them over the end of a shaft, and release to spring into the groove. Ring ID is measured with the ring uninstalled. Use retaining ring pliers (sold separately) to install and remove rings.

Beryllium copper rings conduct electricity and have excellent corrosion resistance. Do not use beryllium copper rings in direct contact with acetylene.

Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
