Rotor Clip SH-34ST Pa External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-34ST PA is an external snap retaining ring designed to secure components on a shaft by seating into a machined groove. Made from SAE 1060-1090 spring steel, this ring fits an 11/32 inch (0.3438 inch decimal) shaft diameter and seats in a groove diameter of 0.321 inches. The phosphate finish provides baseline corrosion resistance. With a ring thickness of 0.025 inches and a hardness rating of 69.5 to 73 HRC, the ring delivers consistent retention force under load. Machinists, maintenance technicians, and assembly professionals working on rotating shaft assemblies, gearboxes, and mechanical drive components are the typical installers of this part.

This external retaining ring is used in industrial and mechanical assembly applications where a reliable, low-profile shaft retention method is required. Typical installations include electric motor shafts, pump assemblies, conveyor components, and precision mechanical sub-assemblies. The ring is sold in a minimum order quantity of 100 pieces per package, making it appropriate for production assembly lines or service shops maintaining inventory of common shaft sizes. Its inch-system dimensions make it a direct fit for standard SAE shaft tolerances in domestic and commercial equipment.

Installation Notes

External snap rings of this type are installed and removed using snap ring pliers sized for external rings. Power down and de-energize any equipment before servicing shaft assemblies. Inspect the shaft groove for burrs or dimensional irregularities before seating the ring, as groove damage can compromise retention. Follow applicable machinery safety standards and equipment manufacturer guidelines during assembly and disassembly.
