Rotor Clip SH-40SS External Retaining Ring 13/32 in Shaft

Product Description

The ROTOR CLIP SH-40SS is an external retaining ring designed to secure components on a shaft by seating into a precision-machined groove. Built from 15-7 grade 632 stainless steel with a zinc finish, this ring is suited for applications where corrosion resistance and high hardness are required. It fits a 13/32-inch (0.4063-inch decimal) shaft diameter with a groove diameter of 0.382 inches and a ring thickness of 0.025 inches. Hardness runs 69.5 to 73 HRC, making it appropriate for high-stress assemblies. Licensed mechanics, maintenance technicians, and industrial assembly professionals are the typical installers for this type of fastener.

The SH-40SS is used in mechanical assemblies where an external snap ring is needed to retain a bearing, gear, pulley, or similar component on a shaft. Its compact free outside diameter of 0.63 inches suits tight-clearance designs. The zinc finish provides baseline corrosion protection in moderate environments. This ring conforms to AMS-5529 and UNS S15700 standards, making it appropriate for applications with defined material traceability requirements, including those operating under ISO 13485:2015-aligned quality systems.

Key Features

• Ring thickness of 0.025 inches with tight tolerance of -0.002 to +0.002 inches
• Meets AMS-5529 and UNS S15700 material standards with ISO 13485:2015 traceability support
• Free outside diameter of 0.63 inches for installation in close-clearance shaft assemblies

Compatibility

Designed as an OEM-style external retaining ring for shafts with a 13/32-inch (0.4063-inch) diameter and a groove width of 0.029 inches. Suitable for mechanical assemblies requiring AMS-5529 or UNS S15700 compliant stainless steel snap rings.

Installation Notes

External retaining rings of this type are installed and removed using snap ring pliers sized for external rings. Always relieve mechanical load from the shaft assembly before removal or installation. Inspect the groove dimensions against the specified tolerances before seating the ring to avoid improper retention. Follow applicable ASME or industry standards for fastener installation in the target assembly.
