Rotor Clip SH-37SS Mps External Retaining Ring 3/8 in

Product Description

The ROTOR CLIP SH-37SS MPS is an external retaining ring engineered for precision shaft retention in demanding mechanical assemblies. Manufactured from 15-7 Grade 632 stainless steel and processed to an AMS-5529 specification, this ring seats in a machined groove on a 3/8-inch shaft, providing a reliable axial stop without the need for threading or welding. The ring measures 0.025 inches in thickness with a groove width of 0.029 inches and a groove diameter of 0.352 inches. Its passivated finish enhances corrosion resistance, making it suitable for environments where standard carbon steel hardware would degrade. Machinists, maintenance technicians, and mechanical assemblers working in HVAC, fluid handling, or industrial equipment applications install this type of ring using standard retaining ring pliers.

This external retaining ring is used in applications requiring a compact, corrosion-resistant shaft stop on 3/8-inch diameter shafts. Typical install scenarios include motor shaft assemblies, pump components, valve actuators, and precision mechanical subassemblies found in commercial and industrial equipment. The passivated stainless steel construction makes it appropriate for wet, chemically active, or high-cleanliness environments where part integrity over service life is critical.

Key Features

• 15-7 Grade 632 stainless steel construction meets AMS-5529 and UNS S15700 specifications

Compatibility

Designed for use on 3/8-inch diameter shafts (9.53 mm) with a groove diameter of 0.352 inches. Consult shaft groove specifications against the stated tolerances before installation to confirm fitment.

Installation Notes

External retaining rings of this type are installed and removed using retaining ring pliers sized for the ring's lug holes — do not use improvised tools that can deform the ring or damage the groove. Ensure the shaft groove is clean, free of burrs, and within the specified groove width and depth tolerances before seating the ring. Depower any rotating or pressurized equipment fully before servicing components retained by this ring. A deformed or improperly seated ring should be replaced rather than reused.
