Rotor Clip SH-68ST Zd External Retaining Ring 11/16 in

Product Description

The ROTOR CLIP SH-68ST ZD is an external retaining ring designed to secure components on a shaft by seating into a machined groove. Built from SAE 1060-1090 carbon steel (UNS G10600-G10900) and finished with yellow zinc dichromate plating, this ring provides reliable axial retention with corrosion resistance in industrial and mechanical assemblies. It fits an 11/16-inch (0.6875-inch) shaft with a groove diameter of 0.646 inches. Ring thickness is 0.042 inches and hardness runs 66-71 HRC. Machinists, millwrights, and mechanical assembly technicians are the typical installers of this fastener type.

This external retaining ring is suited for use in rotating shaft assemblies, gearboxes, pumps, motors, and general industrial machinery where positive axial component retention is required. The zinc dichromate finish makes it appropriate for environments with moderate exposure to moisture or mild corrosives. With a minimum order quantity of 100 pieces, it is primarily sourced for production runs, MRO stock, or service shops that regularly replace shaft hardware across multiple units.

Installation Notes

External retaining rings of this type are installed and removed using snap ring pliers sized for external rings — do not use standard pliers, as ring distortion can compromise retention strength. Ensure the shaft groove dimensions match the specified groove diameter, width, and depth before installation. Inspect the groove for burrs or damage that could prevent proper seating. Follow applicable machinery safety procedures and lock out or tag out rotating equipment before servicing shaft assemblies.
