Rotor Clip E-25SS B100 External E Retaining Ring 1/4 in

Product Description

The ROTOR CLIP E-25SS B100 is an external E style retaining ring designed to secure components onto shafts in light-duty fastening applications. Manufactured from 15-7 stainless steel (Grade 632) to AMS-5529 and UNS S15700 standards, this ring provides corrosion resistance and maintains consistent holding force across a range of service environments. It fits a 0.25 inch shaft diameter and seats in a groove measuring 0.021 inches in diameter. With a ring thickness of 0.025 inches and a three-prong design, it delivers reliable axial retention without requiring specialized tools for installation. Licensed HVAC technicians, plumbers, and mechanical assemblers encounter this style of retaining ring in shaft and housing assemblies throughout trade equipment.

This retaining ring is suited for use on 0.25 inch shafts where a compact, corrosion-resistant external fastener is required. It is commonly installed in pumps, motors, valves, and similar rotating or reciprocating mechanical assemblies found in HVAC, plumbing, and pool equipment. The minimum order quantity is 100 pieces, making it appropriate for shop stock or recurring service inventory.

Installation Notes

Installation and removal of E style retaining rings should be performed using appropriately sized retaining ring pliers to avoid deforming the ring or damaging the shaft groove. Ensure the shaft and groove are clean and free of burrs before seating the ring. Confirm the ring is fully seated in the groove before reassembling adjacent components. Disconnect and de-energize any associated equipment before servicing assemblies that contain retaining rings.
