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.
