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.
