Bowed External Retaining Rings
The curved design of these rings works like a spring, taking up play for a tight hold. Open them with retaining ring pliers (sold separately), pass them over the end of a shaft, and release to spring into the groove. Ring ID is measured with the ring uninstalled. The black-phosphate finish is mildly corrosion resistant in dry environments.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Bowed Side-Mount External Retaining Rings
Also known as bowed E-style rings, these have a curved design that works like a spring, taking up play for a tight hold. 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. The black-phosphate finish is mildly corrosion resistant in dry environments.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Bowed Internal Retaining Rings
The curved design of these rings works like a spring, taking up play for a tight hold. Squeeze them with retaining ring pliers (sold separately) to install in the groove inside a bore or housing. Ring OD is measured with the ring uninstalled. The black-phosphate finish is mildly corrosion resistant in dry environments.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
