Rotor Clip SH-34SS External Retaining Ring 11/32 in Shaft

Product Description

The ROTOR CLIP SH-34SS is an external retaining ring engineered for precision shaft retention on 11/32-inch (0.3438-inch decimal) diameter shafts. Manufactured from 15-7 grade 632 stainless steel to AMS-5529 and UNS S15700 standards, this ring delivers high hardness in the 69.5 to 73 HRC range with a zinc-plated finish for added corrosion resistance. The ring seats into a 0.321-inch groove diameter and features a ring thickness of 0.025 inches, making it suitable for compact assemblies where axial load retention must be maintained within a tight dimensional envelope. Licensed tradespeople and mechanical assembly technicians working on precision equipment rely on this type of fastener for reliable, low-profile shaft retention.

The SH-34SS is used in applications where an external retaining ring must hold a component on a shaft without threaded fasteners. Typical install environments include light industrial machinery, HVAC equipment assemblies, pump shafts, and precision mechanical subassemblies requiring ISO 13485:2015-compliant fastener standards. Its small shaft diameter and close-tolerance groove geometry make it appropriate for compact rotating or stationary shaft configurations in both residential and commercial mechanical systems.

Key Features

• Material: 15-7 grade 632 stainless steel per AMS-5529 and UNS S15700
• Zinc-plated finish provides surface corrosion resistance
• High hardness rating of 69.5 to 73 HRC for durability under load
• Groove diameter of 0.321 inches with tolerance of -0.002 to +0.002 inches for precise fit
• Ring thickness of 0.025 inches suits compact shaft assemblies
• Meets ISO 13485:2015 standards, supporting use in regulated manufacturing environments

Compatibility

Designed as an OEM-style external retaining ring for 11/32-inch diameter shafts with a 0.321-inch groove diameter. Verify groove width (0.029 inches) and groove depth (0.011 inches) against shaft specifications before installation.

Installation Notes

Installation requires retaining ring pliers sized for external rings of this diameter; improper tooling can distort the ring or damage the groove. Power down and de-energize all related equipment before servicing any shaft assembly. Confirm shaft groove dimensions match the specified tolerances prior to seating the ring. Do not reuse a ring that has been removed, as repeated installation cycles can compromise retention force.
