Rotor Clip SE-21SS B100 E Style Retaining Ring 7/32 in

Product Description

The ROTOR CLIP SE-21SS B100 is an external E style retaining ring manufactured from 15-7 stainless steel (Grade 632) to AMS-5529 and UNS S15700 standards. Designed for use on shafts with a 7/32 inch (0.2188 inch decimal) diameter, it seats into a groove 0.188 inches in diameter and 0.029 inches wide. At 0.025 inches thick and hardened to 63-69.5 HRC, this ring delivers strong axial retention in demanding environments. Licensed HVAC technicians, plumbers, pump mechanics, and industrial service techs encounter these rings on rotating shafts and assemblies where corrosion resistance and tight dimensional tolerances are required.

This retaining ring is suited for light-duty shaft applications in corrosive or washdown environments where stainless steel is specified over carbon steel. Typical installations include pump shafts, motor shafts, valve stems, and small mechanical assemblies found in HVAC equipment, pool and spa pump components, and plumbing hardware. The E style three-prong design allows installation without special pliers in some configurations, though a proper retaining ring applicator is recommended for consistent seating. Sold in a minimum order quantity of 100 pieces.

Installation Notes

Installation and removal should be performed by a qualified mechanic or technician familiar with retaining ring fasteners. Disengage and de-energize all rotating equipment before servicing shaft assemblies. Use a dedicated E ring applicator or needle-nose pliers designed for retaining rings to seat the ring fully into the groove and avoid over-stressing the prongs. Inspect the groove for burrs or wear before installing a new ring.
