Rotor Clip E-9SS External E Retaining Ring 3/32 in Ss

Product Description

The ROTOR CLIP E-9SS is an external E style retaining ring designed to seat in a circumferential groove on a shaft and resist axial movement of assembled components. Manufactured from 15-7 stainless steel (Grade 632) to AMS-5529 and UNS S15700 standards, it provides strong corrosion resistance for demanding service environments. The ring fits a 3/32 inch (0.0938 inch) shaft diameter with a groove diameter of 0.074 inches and a ring thickness of 0.015 inches. Its three-prong design allows installation and removal with standard E-ring pliers without full disassembly of the shaft assembly. Licensed machinists, maintenance technicians, and assembly professionals commonly use this ring in precision mechanical assemblies.

The E-9SS suits applications where a compact, low-profile retaining solution is needed on small-diameter shafts. It is commonly specified in instrumentation, medical device assemblies, HVAC actuators, small motors, and precision mechanical subassemblies where stainless steel is required for corrosion resistance or cleanliness standards. The ISO 13485:2015 compliance noted in the standards listing makes it appropriate for quality-managed manufacturing environments. This ring is sold individually but carries a minimum order quantity of 100 pieces per order.

Key Features

• Three-prong E style design allows tool-assisted installation without full shaft disassembly
• Ring thickness of 0.015 inches with tolerance of -0.002 to +0.002 inches for precise groove fit
• Hardness rated 82.5 to 86 HR15N for reliable retention under load
• Referenced under ISO 13485:2015, suitable for quality-managed and medical manufacturing environments

Compatibility

Designed as an OEM-style external E style retaining ring for 3/32 inch diameter shafts with a 0.074 inch groove diameter. Verify groove width (0.020 inches) and groove depth (0.010 inches) against the target shaft specification before installation.

Installation Notes

Installation and removal should be performed by qualified mechanical technicians using appropriate E-ring pliers or retaining ring tools sized for this diameter. De-energize and lock out all equipment before servicing any assembly containing this ring. Confirm shaft groove dimensions — diameter, width, and depth — match the ring specification before seating to prevent improper retention or ring fracture. Do not over-stress the ring prongs during installation, as excessive deflection can compromise retention force.
