Rotor Clip SE-31SS B100 E Style Retaining Ring 5/16 in

Product Description

The ROTOR CLIP SE-31SS B100 is an external E style retaining ring engineered for 5/16 inch shafts with a groove diameter of 0.25 inches. Manufactured from 15-7 stainless steel (Grade 632) to AMS-5529 and UNS S15700 standards, this ring delivers high hardness in the range of 63 to 69.5 HRC, making it well suited for corrosion-resistant fastening applications in demanding environments. The three-prong E style configuration allows for quick side-loading installation without special tooling in most cases. Maintenance technicians, mechanical assemblers, and field service professionals working with small-diameter shaft assemblies will find this ring a direct-fit solution where reliable axial retention is required.

This retaining ring is commonly used in industrial and mechanical assemblies where compact shaft retention is needed on 5/16 inch diameter shafts. Typical applications include motors, pumps, HVAC blower assemblies, and other rotating or reciprocating shaft systems requiring a low-profile external retainer. The stainless steel construction makes it appropriate for environments with exposure to moisture, mild chemicals, or temperature cycling. It is sold in a minimum order quantity of 100 pieces per order.

Installation Notes

Installation and removal should be performed by a qualified mechanical technician using appropriate retaining ring pliers sized for E style rings. Ensure the shaft assembly is depressurized, de-energized, and stationary before servicing any components retained by this ring. Do not reuse a ring that has been visibly deformed or overstressed during removal. Verify groove dimensions match the ring specifications before installation to prevent ring walk or ejection under load.
