Rotor Clip SH-37ST Pa B100 External Snap Ring 3/8 in

Product Description

The ROTOR CLIP SH-37ST PA B100 is an external snap retaining ring designed for 3/8-inch (0.375 inches) shaft diameters with a groove diameter of 0.352 inches. Manufactured from SAE 1060-1090 spring steel (UNS G10600-G10900), it delivers hardness in the 69.5 to 73 HRC range for reliable retention under load. The phosphate finish provides basic corrosion resistance and surface conditioning. This ring measures 0.025 inches thick and seats into a groove 0.029 inches wide and 0.012 inches deep. It is sold in a minimum order quantity of 100 pieces per package. Installation is performed by machinists, maintenance technicians, and assembly professionals working with shafts, gears, pulleys, and similar rotating or sliding components.

This external snap ring is suited for light-duty to medium-duty industrial assembly applications where a compact, reliable axial retention solution is required. Typical uses include securing components on shafts in motors, pumps, gear assemblies, and general mechanical equipment. The phosphate finish is appropriate for indoor or controlled-environment use. This part follows inch-system dimensioning and is well matched to North American mechanical assembly standards. It is packaged in quantities of 100 to support production and service operations that require consistent, repeat-use fastener stock.

Compatibility

Designed as a standard external snap retaining ring for 3/8-inch shafts in mechanical assemblies requiring axial component retention. Consult shaft and groove dimensional specifications to confirm fit before installation.

Installation Notes

External snap rings of this type are installed and removed using snap ring pliers sized for external-type rings. Always power down or de-energize any equipment and relieve any mechanical load before servicing components secured by retaining rings. Verify groove dimensions match the ring specifications before installation to prevent improper seating or ring failure. Follow applicable machinery safety standards and manufacturer assembly guidelines for the host equipment.
