Rotor Clip E-87SS B100 External E Style Retaining Ring

Product Description

The ROTOR CLIP E-87SS B100 is an external E style retaining ring designed to seat in a groove on a shaft and provide positive axial retention without the need for threading, clamping, or adhesive. Manufactured from 15-7 grade 632 stainless steel (AMS-5529, UNS S15700), this ring is suited for applications requiring corrosion resistance and elevated hardness. It fits a 7/8 inch (0.875 inch) shaft diameter with a groove diameter of 0.675 inches and a ring thickness of 0.05 inches. Hardness is rated at 37-43 HRC. The three-prong E style design allows for tool-free or plier-assisted installation from the side of the shaft, which is useful in confined assemblies where snap ring pliers cannot access the shaft end.

This retaining ring is used across industrial, mechanical, and trade equipment assemblies wherever a 7/8 inch shaft requires external retention in a standard E style groove. Typical applications include pump shafts, motor shafts, actuator assemblies, and similar rotating or sliding components found in HVAC equipment, fluid handling systems, and electrical drive assemblies. The stainless steel construction makes it appropriate for wet or corrosive environments where carbon steel rings would degrade. Installation is performed by maintenance technicians and mechanical assemblers as part of component replacement or new assembly work.

Key Features

• Hardness of 37-43 HRC provides strong retention under dynamic and axial loading
• Groove diameter of 0.675 inches with a tight groove diameter tolerance of 0.000 to 0.003 inches for precise fitment
• Ring thickness of 0.05 inches with a tolerance of -0.002 to 0.002 inches
• Meets AMS-5529, UNS S15700, and ISO 13485:2015 standards

Compatibility

Designed as an OEM-style external E style retaining ring for 7/8 inch shaft diameter applications requiring a groove diameter of 0.675 inches. Verify groove width (0.056 inches) and groove depth (0.1 inches) against the host shaft specification before installation.

Installation Notes

Installation and removal of E style retaining rings should be performed by a qualified mechanic or assembly technician using appropriate retaining ring pliers or a flat-blade tool suited to E style rings. Always de-energize and lock out the equipment before servicing any shaft assembly. Inspect the shaft groove for burrs, corrosion, or dimensional non-conformance before seating the ring. Do not reuse a ring that has been deformed or over-stressed during a previous removal.
