External Retaining Rings
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.

Side-Mount External Retaining Rings
Also known as E-style rings, these rings have three prongs that make contact with the shaft and provide a wider shoulder than other external rings for a larger retaining surface. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. Ring OD is measured with the ring uninstalled.
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.

Heavy Duty Side-Mount External Retaining Rings
Also known as reinforced E-style rings, these rings are reinforced to withstand faster rotation than other side-mount retaining rings. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. They fit in the same grooves as standard E-style rings. Ring OD is measured with the ring uninstalled.
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.
