Rotor Clip SH-75ST Mcd External Retaining Ring 3/4 in

Product Description

The ROTOR CLIP SH-75ST MCD is an external retaining ring designed for use on 3/4-inch diameter shafts. It seats into a precision groove machined into the shaft OD, providing a positive stop that retains components such as bearings, gears, and collars against axial movement. Manufactured from SAE 1060-1090 spring steel (UNS G10600-G10900) and finished with a cadmium plating for corrosion resistance, this ring measures 0.042 inches in thickness with a groove diameter of 0.704 inches. Installation and removal are performed by licensed machinists, maintenance technicians, and mechanical assemblers using standard snap-ring pliers.

This retaining ring is suited for industrial, mechanical, and OEM assembly applications where a removable, external shaft-retention method is required. Typical scenarios include gearbox assembly, pump shaft retention, motor shaft component securing, and general mechanical power-transmission assemblies. Its cadmium finish provides added resistance to corrosion in moderate-duty environments. The ring meets Military Specification MS 16624-1075 and conforms to ISO 13485:2015, making it appropriate for regulated manufacturing environments as well.

Compatibility

Designed as an OEM-style external retaining ring for 3/4-inch diameter shafts with a groove diameter of 0.704 inches. Groove width tolerance is 0.000 to 0.003 inches; verify shaft groove dimensions before installation.

Installation Notes

Installation and removal require snap-ring pliers sized for external rings. Always de-energize and lock out equipment before servicing any assembly containing this ring. Do not over-expand the ring beyond the minimum necessary to clear the shaft, as excessive deflection can compromise spring tension and retention force. Verify groove dimensions match the specified tolerances prior to installation.
