Rotor Clip SH-125ST Pa External Retaining Ring 1.25 in 25 Pack

Product Description

The ROTOR CLIP SH-125ST PA is an external SH style retaining ring designed to seat in a machined groove on a shaft and retain assembled components against axial movement. Made from spring steel with a phosphate finish, it fits a 1.25-inch shaft diameter and seats in a groove measuring 1.176 inches in diameter and 0.056 inches wide. With a thrust load capacity of 7,460 pounds, this ring handles demanding mechanical loads in rotating and stationary shaft assemblies. It is installed and serviced by maintenance technicians, millwrights, and mechanical assemblers working in industrial, HVAC, pump, and power-transmission applications.

This retaining ring is suited for external groove applications on 1.25-inch shafts in residential and commercial mechanical assemblies. Typical install scenarios include motors, gearboxes, pump shafts, and HVAC fan assemblies where positive axial retention is required without threaded fasteners. The phosphate finish provides a base-level corrosion inhibitor appropriate for indoor and moderately protected environments. Each package contains 25 rings.

Installation Notes

Retaining rings of this style are installed and removed using external snap ring pliers sized for SH style rings. Always de-energize and lock out any equipment before servicing shafts or replacing retaining rings. Inspect the shaft groove for wear, burrs, or dimensional deviation before installing a new ring. Do not over-spread the ring during installation, as exceeding the elastic limit will compromise retention performance.
