Rotor Clip SH-56ST Zd External Retaining Ring 9/16 in

Product Description

The ROTOR CLIP SH-56ST ZD is an external retaining ring designed to secure components on shafts by seating into a machined groove on the shaft's outer diameter. Made from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, it provides corrosion resistance in typical industrial and mechanical service environments. The ring fits a 9/16 inch (0.5625 inch) shaft diameter with a groove diameter of 0.530 inches and a ring thickness of 0.035 inches. It is installed by qualified mechanical or maintenance technicians working on shafts, assemblies, and rotating equipment across a wide range of industries.

This external retaining ring is suited for use in shaft assemblies where a reliable, low-profile fastening method is required without threading or welding. Typical applications include HVAC equipment, motors, pumps, gear assemblies, and general industrial machinery. The zinc-plated finish makes it appropriate for indoor and light-duty applications where moderate corrosion resistance is acceptable. This ring is sold individually with a minimum order quantity of 100 units, making it appropriate for service shops and production environments maintaining consistent fastener inventory.

Installation Notes

External retaining rings of this type are installed and removed by mechanical technicians using snap ring pliers sized for external rings. Always confirm the shaft groove dimensions match the ring specifications before installation to prevent ring failure or shaft damage. De-energize and lock out all equipment per applicable safety procedures before servicing any shaft assembly. Do not reuse a retaining ring that has been removed, as the ring may have deformed beyond reliable service tolerances.
