Rotor Clip SH-43ST Zd External Retaining Ring 7/16 in

Product Description

The ROTOR CLIP SH-43ST ZD is an external retaining ring engineered for use on 7/16-inch (0.4375-inch) diameter shafts. It seats into a precision groove with a 0.412-inch groove diameter and a 0.029-inch groove width, locking components axially on shafts in mechanical assemblies. Manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, the ring delivers corrosion resistance alongside a hardness rating of 69.5 to 73 HRC. At 0.025 inches thick and 0.66 inches in free outside diameter, it is a compact, high-strength fastening solution installed by maintenance technicians and mechanical assemblers across industrial and trade applications.

This external retaining ring is suited for general mechanical assemblies where a reliable shaft-mounted fastener is required. Typical applications include motors, pumps, gearboxes, and similar rotating or stationary shaft assemblies found in HVAC equipment, plumbing system components, and light industrial machinery. It is supplied individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock, production-line use, or service-fleet inventory replenishment.

Compatibility

Designed as an OEM-style external retaining ring for mechanical shaft assemblies requiring a 7/16-inch shaft diameter and a 0.412-inch groove diameter per SAE 1060-1090 and UNS G10600-G10900 fastener standards.

Installation Notes

External retaining rings of this type are installed and removed by qualified mechanical technicians using appropriate snap-ring pliers sized for external rings. De-energize and lock out all power to the equipment before servicing any shaft assembly. Verify groove dimensions and shaft diameter against ring specifications before installation to ensure proper seating and retention. Do not over-spread the ring during installation, as exceeding elastic limits will deform the ring and compromise retention.
