Self-Locking External Retaining Rings
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.
1060-1090 spring steel has good strength. A black-phosphate finish is mildly corrosion resistant in dry environments. A zinc yellow-chromate plated finish is mildly corrosion resistant in wet environments.
15-7 PH stainless steel has high strength with good corrosion resistance. These rings are passivated for extra protection against corrosion.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
