No groove is required for these light duty rings—their thick profile helps them grip the shaft. Open them with retaining ring pliers (sold separately), pass them over the end of a shaft, and release to install. 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.
