Rotor Clip SE-11ST Pa E Style Retaining Ring 7/64 in

Product Description

The ROTOR CLIP SE-11ST PA is an external E style retaining ring designed to secure components on small-diameter shafts without the need for threads, pins, or snap grooves machined into the shaft end. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, this ring fits a 7/64 inch (0.1094 inch decimal) shaft diameter and seats into a groove with a 0.079 inch diameter. Ring thickness is 0.015 inches and groove width is 0.020 inches. The three-prong E style design allows for quick installation and removal using standard retaining ring pliers, making it a standard fastener choice in precision assemblies across mechanical, industrial, and light trade applications.

This retaining ring is suited for use in small shaft assemblies where axial retention of gears, pulleys, bearings, or collars is required. Its compact free outside diameter of 0.375 inches and free diameter of 0.076 inches make it appropriate for tight-clearance assemblies. The phosphate finish provides a baseline level of corrosion resistance and surface lubricity. Mechanical assemblers, maintenance technicians, and industrial tradespeople typically install this ring during equipment assembly or field repair of motors, pumps, and actuators. Minimum order quantity is 100 pieces.

Installation Notes

Installation and removal of E style retaining rings should be performed by a qualified mechanical technician using appropriate retaining ring pliers sized for this ring diameter. Ensure the shaft assembly is fully de-energized and depressurized before servicing any components secured by this ring. Do not over-stress the ring prongs during installation, as spring steel rings can fracture if spread beyond their designed working range. Confirm groove dimensions match the ring specifications before installation to ensure proper seating and retention.
