Rotor Clip E-43ST Pa B100 E Style Retaining Ring 7/16 in

Product Description

The ROTOR CLIP E-43ST PA B100 is an external E style retaining ring designed to seat in a machined groove on a shaft and prevent axial movement of assembled components. Built from SAE 1060-1090 steel with a phosphate finish, it fits a 7/16 inch shaft diameter with a groove diameter of 0.343 inches. At 0.035 inches thick and hardened to 37-43 HRC, this ring delivers reliable retention in high-cycle mechanical assemblies. It is installed and removed by machinists, maintenance technicians, and assembly personnel working on motors, gearboxes, pumps, and similar rotating equipment where compact axial retention is required.

This retaining ring is suited for use on 7/16 inch shafts in both light industrial and commercial mechanical assemblies. The E style three-prong design allows installation without specialized pliers in many configurations, making it a common choice in motor shaft applications, pump assemblies, and equipment requiring frequent disassembly for service. The phosphate finish provides mild corrosion resistance for indoor and protected environments. Minimum order quantity is 100 pieces per order.

Installation Notes

Power down and de-energize any equipment before servicing components that use this retaining ring. Ensure the shaft groove is clean and within specified tolerance before seating the ring. Use appropriate retaining ring pliers or a flat-blade tool suited to E style rings to avoid distorting the prongs during installation or removal. Inspect the ring for deformation after removal — do not reuse a ring that has been oversprung or visibly deformed.
