Rotor Clip E-9ST Pa External E Style Retaining Ring

Product Description

The ROTOR CLIP E-9ST PA is an external E style retaining ring designed to secure components on small-diameter shafts in mechanical assemblies. It fits a 3/32 inch (0.0938 inch decimal) shaft diameter and seats in a groove measuring 0.074 inches in diameter and 0.020 inches wide. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900) with a phosphate finish, the ring provides corrosion resistance and consistent clamping performance. Hardness is rated at 84.5 to 87 HR15N. The three-prong E style design allows for quick lateral installation without removing the shaft from the assembly. This part is typically installed by mechanical technicians and maintenance professionals working on precision shaft assemblies.

This retaining ring is suited for use in compact mechanical, electromechanical, and light industrial applications where small-shaft retention is required. The E style configuration is commonly found in motor shafts, actuator assemblies, and precision instrument housings. Its small profile makes it appropriate for tight-clearance designs. Minimum order quantity is 100 units, making it a standard production or service-stock fastener. It meets SAE 1060-1090 and ISO 13485:2015 standards, supporting use in regulated manufacturing environments.

Installation Notes

Install and remove E style retaining rings using retaining ring pliers sized for the groove dimensions to avoid deforming the ring or damaging the groove. De-energize and lock out any equipment before servicing shaft assemblies containing retaining rings. Inspect the groove for burrs or dimensional damage before seating the ring. Do not reuse a ring that has been deformed or over-expanded during removal.
