Rotor Clip SH-187SS Mps Snap Retaining Ring 1-7/8 in

Product Description

The ROTOR CLIP SH-187SS MPS is an external snap retaining ring designed to secure components on a shaft by seating into a precision-machined groove. Built from 15-7 Grade 632 stainless steel and passivated for corrosion resistance, this ring meets AMS-5529 and UNS S15700 material standards. It is sized for a 1-7/8 inch shaft diameter with a groove diameter of 1.769 inches and a ring thickness of 0.062 inches. Licensed tradespeople and MRO professionals working on industrial assemblies, pumps, motors, and mechanical subassemblies rely on this type of fastener to maintain precise axial positioning without welding or threading.

This retaining ring is suited for use in applications requiring corrosion-resistant fastening, including marine, food processing, chemical processing, and medical-adjacent environments where stainless hardware is specified. The passivated finish provides an added layer of oxidation resistance. It conforms to Military Specification MS 16624-4187 and ISO 13485:2015, making it appropriate for assemblies held to defense or regulated-industry standards. Minimum order quantity is 100 pieces, with individual unit packaging. This part is intended for professional installation in mechanical and industrial assembly contexts.

Installation Notes

Installation and removal of external snap retaining rings requires the use of proper external snap ring pliers to avoid deforming the ring or damaging the groove. De-energize and lock out all rotating or powered equipment before servicing any shaft-mounted assembly. Confirm groove dimensions match the ring specifications before installation, as an incorrect fit compromises axial retention. Follow all applicable facility safety and mechanical assembly standards during installation.
