Rotor Clip HO-87ST Mcd Internal Snap Ring 7/8 in Steel

Product Description

The ROTOR CLIP HO-87ST MCD is a steel internal snap retaining ring designed to secure components within a bored housing by seating in a precision-machined groove. With a 7/8-inch bore diameter and a ring thickness of 1.07mm (0.042 inches), it delivers reliable axial retention in applications where groove integrity and load capacity are critical. The cadmium finish provides corrosion resistance in demanding environments. Rated at a groove safety factor thrust load capacity of 2,080 pounds and a ring safety factor of 5,227 pounds, this ring is built for high-stress industrial and military-spec assemblies. It is installed by qualified mechanical and assembly technicians working on precision equipment.

This internal retaining ring is suited for use in industrial machinery, military equipment, aerospace-adjacent assemblies, and other applications requiring components that meet strict dimensional and material standards. The HO-87ST MCD meets multiple Military Specifications including MS 16625-1025, MS 16625-1050, MS 16625-1062, MS 16625-1075, MS 16625-1087, MS 16625-1100, MS 16625-1125, MS 16625-1137, MS 16625-1150, MS 16625-1162, and MS 16625-1187. It is appropriate for both OEM production builds and field-replacement scenarios where mil-spec compliance is required.

Installation Notes

Internal snap rings of this type are installed using snap ring pliers sized for internal rings — use the correct tip style to avoid ring distortion or eye injury. Power down and de-energize any equipment fully before disassembling housings or bearing bores. Verify groove diameter, groove width, and groove depth against the ring specifications before installation to ensure proper seating and load transfer. Follow applicable facility safety procedures and any governing military or industrial maintenance standards for the equipment being serviced.
