Rotor Clip SH-87ST Mcd External Retaining Ring 7/8 in

Product Description

The ROTOR CLIP SH-87ST MCD is an external retaining ring designed to secure components on a 7/8 inch (0.875 inch) shaft. It seats into a machined groove and holds assemblies axially in place without threading or welding. Made from SAE 1060-1090 spring steel with a cadmium finish, this ring delivers reliable corrosion resistance and spring-back retention force. Hardness is rated at 47-53 HRC. The groove diameter is 0.821 inches, ring thickness is 0.042 inches, and groove width is 0.046 inches. Machinists, maintenance technicians, and assembly professionals install this ring in rotating shaft and bearing applications across industrial and mechanical systems.

This external retaining ring is suited for use in industrial machinery, rotating equipment, and mechanical assemblies where a 7/8 inch shaft diameter and corresponding groove geometry are present. It is appropriate for applications requiring a cadmium-plated finish for added corrosion protection. The ring meets Military Specification MS 16624-1087 and conforms to SAE 1060-1090 and UNS G10600-G10900 standards, making it a fit for both commercial and mil-spec maintenance contexts. Typical uses include pump shafts, gearboxes, conveyor components, and similar rotating assemblies.

Installation Notes

External retaining rings of this type are installed and removed using snap ring pliers sized for external rings. Always power down and de-energize equipment before servicing shaft assemblies. Inspect the groove for burrs, wear, or out-of-tolerance dimensions before seating the ring. Do not reuse a ring that has been overstressed or deformed during removal.
