Low-Clearance Side-Mount External Retaining Rings

Also known as C-style and crescent rings, these rings have a small shoulder to fit in tight spaces. 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.

1060-1090 spring steel rings are an economical choice with good strength. A black-phosphate finish is mildly corrosion resistant in dry environments, while a zinc yellow-chromate plated finish is 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.

DIN 1.4122 stainless steel rings withstand wear caused by abrasion, similar to 400 series stainless steel. 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.
