Rotor Clip SH-50ST Pa B100 External Snap Ring 1/2 in

Product Description

The ROTOR CLIP SH-50ST PA B100 is an external snap retaining ring designed to secure components on a shaft by seating in a machined groove. Built from SAE 1060-1090 spring steel, this ring delivers the elasticity and hardness needed to withstand dynamic loads and repeated assembly cycles. It features a phosphate finish for corrosion resistance in typical service environments. With a shaft diameter of 0.5 inches, a groove diameter of 0.468 inches, and a ring thickness of 0.035 inches, it is sized for precise fitment in standard external-groove applications. This part is installed by maintenance technicians, machine builders, and trade professionals working on rotating assemblies, drive shafts, and mechanical fastening applications.

This retaining ring is suited for use in residential and commercial mechanical assemblies where an external groove is machined onto a 0.5 inch shaft. Typical installation scenarios include electric motors, pumps, gear assemblies, and HVAC blower shafts where axial retention of a component is required without threading or welding. The ring seats fully into a 0.039 inch wide groove with a depth of 0.016 inches. This SKU ships in a minimum order quantity of 100 rings per package, making it appropriate for production runs, service fleets, and stocking distributors.

Compatibility

Designed as an OEM-style external retaining ring for shafts with a 0.5 inch diameter and a machined external groove conforming to SAE 1060-1090 groove standards. Verify groove width and depth against shaft specifications before installation.

Installation Notes

Installation is performed with external snap ring pliers sized for the ring free outside diameter of 0.77 inches. Ensure the shaft groove is clean and free of burrs or debris before seating the ring. Verify that groove dimensions fall within the specified tolerances to prevent ring walk or ejection under load. Always wear eye protection when installing or removing snap rings, as the ring can release under tension if pliers slip.
