Rotor Clip E-87ST Zd External E Retaining Ring 7/8 in

Product Description

The ROTOR CLIP E-87ST ZD is an external E style retaining ring designed to secure components on a 7/8-inch shaft. The ring seats into a groove machined to a 0.675-inch groove diameter and provides axial retention without requiring a groove all the way around the shaft. Manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, it delivers a hardness of 37-43 HRC and corrosion resistance suitable for general industrial and mechanical applications. The three-prong E style design allows fast side-loading installation without disassembling the shaft assembly. Licensed HVAC, plumbing, and mechanical technicians working on rotating or sliding shaft components rely on this ring type for quick field replacement and maintenance.

This retaining ring is used in shaft assemblies across a wide range of trade applications including HVAC equipment, pumps, fan assemblies, and light mechanical equipment where a 7/8-inch shaft diameter is present. The E style profile is particularly suited to applications where end-of-shaft access is restricted, since the ring installs from the side. It is a direct-fit replacement wherever a standard E style external ring with a 0.675-inch groove diameter is specified.

Installation Notes

Installation and removal of E style retaining rings should be performed using appropriate retaining ring pliers to avoid deforming the ring or damaging the groove. Verify groove diameter and groove width dimensions before installation to confirm proper fit and retention capacity. Always inspect the shaft groove for burrs or damage before seating the ring. Follow applicable equipment manufacturer service procedures and relevant mechanical codes when servicing rotating shaft assemblies.
