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

Product Description

The ROTOR CLIP SH-37ST MCD is an external retaining ring designed to secure components on a 3/8-inch shaft. Manufactured from SAE 1060-1090 spring steel with a cadmium finish, it provides reliable axial retention in rotating or stationary assemblies. The ring seats into a machined groove with a 0.352-inch groove diameter and a 0.029-inch groove width. At 0.025 inches thick and hardened to 69.5-73 HRC, it delivers consistent holding force under mechanical load. Licensed machinists, maintenance technicians, and assembly professionals install this ring type across a wide range of industrial and mechanical applications.

This retaining ring is suited for use in light-duty to medium-duty shaft assemblies where a compact external ring is required. It fits a 3/8-inch shaft and is appropriate for applications in motors, gearboxes, pumps, and similar rotating equipment. The cadmium plating provides corrosion resistance in environments where moisture or mild chemical exposure is present. This ring meets Military Specification MS 16624-1037 and conforms to ISO 13485:2015, making it appropriate for precision assemblies with strict documentation requirements.

Installation Notes

External retaining rings are installed and removed using snap ring pliers sized for external rings. Power down and de-energize any equipment before servicing shaft assemblies. Inspect the groove for burrs or damage that could affect ring seating. Rings should not be over-expanded during installation, as this can compromise the temper and holding capacity of the ring.
