Heavy Duty External Retaining Rings
Thicker than standard external retaining rings, these rings withstand greater force. 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.
1060-1090 spring steel rings are an economical choice with 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 rings are high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
