Rotor Clip SH-37ST Zd External Retaining Ring 3/8 in

Product Description

The ROTOR CLIP SH-37ST ZD is an external retaining ring designed to secure components on shafts in assemblies where a low-profile, reliable retention solution is required. Manufactured from SAE 1060-1090 carbon steel and finished with yellow zinc dichromate plating, this ring fits a 3/8 inch (0.375 inch) shaft diameter with a groove diameter of 0.352 inches. The ring measures 0.025 inches thick and seats into a groove 0.029 inches wide and 0.012 inches deep. It is installed by licensed maintenance technicians, mechanical assemblers, and field service professionals working across industrial, HVAC, and mechanical system applications.

This external retaining ring is suited for use on shafts in rotating or stationary assemblies requiring positive axial retention without threaded fasteners. It is appropriate for residential and commercial mechanical equipment, including motors, pumps, gearboxes, and similar shaft-driven components. The zinc dichromate finish provides a corrosion-resistant barrier suitable for moderate-duty environments. Sold individually with a minimum order quantity of 100 units, this ring is intended for production and service applications alike.

Installation Notes

External retaining rings of this type are installed using ring pliers sized for the application. Ensure the shaft groove dimensions match the ring specifications before installation to prevent improper seating. De-energize and lock out all equipment before performing any shaft or assembly service. Do not reuse a ring that has been removed, as the retention force may be compromised.
