Rotor Clip SE-74SS B100 E Style Retaining Ring 3/4 in

Product Description

The ROTOR CLIP SE-74SS B100 is an external E style retaining ring engineered for 0.750 inch (3/4 inch) shaft diameters. Manufactured from 15-7 grade 632 stainless steel and conforming to AMS-5529 and UNS S15700 standards, this ring delivers high hardness in the 44-51 HRC range, making it suitable for demanding mechanical and industrial applications. With a groove diameter of 0.625 inches and a ring thickness of 0.050 inches, it seats securely in a precision-cut groove. The three-prong E style design allows for lateral installation without requiring shaft disassembly, reducing labor time on assemblies where end access is restricted.

This retaining ring is used in mechanical assemblies where a shaft-mounted component must be axially retained without threading or welding. Typical applications include rotating shafts in pumps, motors, gearboxes, and similar equipment found in HVAC, plumbing, and industrial service environments. The stainless steel construction resists corrosion in wet or chemically active settings. Licensed mechanics, millwrights, and equipment service technicians are the primary installers in both residential and light commercial maintenance contexts.

Key Features

• E style three-prong design allows side-loading onto shaft without full disassembly
• 15-7 grade 632 stainless steel construction for corrosion resistance and high hardness
• Hardness rating of 44-51 HRC for wear resistance in dynamic assemblies
• Meets AMS-5529 and UNS S15700 fastener standards
• Groove width of 0.056 inches with tight tolerance for secure axial retention
• Free outside diameter of 1.000 inch provides clear visual confirmation of proper seating

Compatibility

Designed as an OEM-style external retaining ring for 3/4 inch shafts with a 0.625 inch groove diameter. Confirm groove width, groove depth, and shaft diameter against mechanical drawings before installation.

Installation Notes

Installation should be performed by a qualified mechanic or technician using appropriate retaining ring pliers rated for E style rings. Ensure the shaft and groove are free of burrs, debris, and corrosion before seating the ring. De-energize and lock out all rotating equipment before servicing any shaft assembly. Verify groove tolerances against the specification to prevent ring walk or ejection under load.
