Rotor Clip E-43SS B100 External E Style Retaining Ring

Product Description

The ROTOR CLIP E-43SS B100 is an external E style retaining ring designed to secure components on shafts in demanding mechanical assemblies. Manufactured from 15-7 stainless steel (Grade 632) and compliant with AMS-5529 and UNS S15700 standards, it provides reliable axial retention where corrosion resistance and high hardness are required. The ring fits a 7/16 inch shaft diameter with a groove diameter of 0.343 inches and a ring thickness of 0.035 inches. Its three-prong E style design allows for fast installation and removal without specialized tooling, making it well suited for maintenance-intensive applications across industrial, HVAC, and mechanical service environments.

This retaining ring is used in applications where a compact, corrosion-resistant fastener is needed on small-diameter shafts. Common install scenarios include blower assemblies, fan shaft retention, pump components, and precision mechanical linkages found in HVAC equipment, plumbing systems, and industrial machinery. The 15-7 stainless steel construction is appropriate for environments exposed to moisture, mild chemicals, or elevated temperatures where carbon steel rings would corrode or lose integrity over time.

Key Features

• Free outside diameter of 0.687 inches allows positive retention across the groove
• Groove width of 0.039 inches with tolerance of 0.000 to 0.003 inches for precise fit

Compatibility

Designed as an OEM-style external retaining ring for 7/16 inch diameter shafts requiring a 0.343 inch groove diameter; verify groove width and depth specifications against the shaft assembly before installation.

Installation Notes

External E style retaining rings are typically installed and removed by maintenance technicians and mechanical tradespeople using retaining ring pliers or a flat-blade tool applied to the prongs. Relieve all load from the shaft and de-energize the equipment before servicing any rotating assembly. Confirm groove dimensions match the ring specifications to prevent ring walk or ejection under load. Do not reuse a ring that has been overstressed, deformed, or shows signs of corrosion fatigue.
