Rotor Clip E-18SS B100 Retaining Ring 3/16 in Shaft Ss

Product Description

The ROTOR CLIP E-18SS B100 is an external E style retaining ring designed to seat in a groove on a 3/16-inch shaft and retain components against axial movement. Manufactured from 15-7 grade 632 stainless steel and conforming to AMS-5529 and UNS S15700, this ring delivers corrosion resistance and consistent spring force in demanding environments. The ring measures 0.025 inches thick, seats in a groove 0.029 inches wide and 0.020 inches deep, and features a free outside diameter of 0.335 inches. Three prongs provide secure engagement with the groove wall. This part is sold in multiples of 100 units per order with a package quantity of 1.

E style retaining rings of this size are commonly used in precision assemblies found in fluid handling, HVAC actuator mechanisms, pump shafts, and other mechanical subassemblies where a low-profile external ring is required on a small-diameter shaft. The stainless steel construction suits applications exposed to moisture, mild chemicals, or temperature cycling. Licensed assembly technicians, mechanical contractors, and OEM service shops typically use this ring when servicing or building equipment with 3/16-inch shafts requiring axial retention.

Installation Notes

Install and remove E style retaining rings using appropriate retaining ring pliers sized for the prong holes to avoid distorting the ring or damaging the groove. Power down or depressurize the assembly before disassembly. Inspect the shaft groove for burrs or damage before seating the ring, as groove irregularities can prevent full engagement. Consult applicable mechanical assembly standards and equipment manufacturer documentation when specifying this ring in a new design.
