Rotor Clip SH-62ST Zd External Retaining Ring 5/8 in

Product Description

The ROTOR CLIP SH-62ST ZD is an external retaining ring designed for 5/8 inch (0.625 inch) shaft diameters with a groove diameter of 0.588 inches. Manufactured from SAE 1060-1090 carbon steel and finished with yellow zinc dichromate plating, this ring provides corrosion resistance and a hardness rating of 66-71 HRC. The zinc-plated finish helps protect against oxidation in moderate service environments. Licensed HVAC technicians, plumbers, millwrights, and mechanical assemblers use external retaining rings like this one to secure components onto shafts and prevent axial movement without threaded fasteners or welding.

This retaining ring is suited for use in rotating shaft assemblies, pump components, motor shafts, gear assemblies, and similar mechanical systems where a precise, low-profile axial stop is required. With a free outside diameter of 0.9 inches and a ring thickness of 0.035 inches, it fits into standard external grooves machined to SAE and UNS G10600-G10900 specifications. It is appropriate for both light industrial and commercial mechanical assembly applications. The minimum order quantity for this part is 100 units, packaged individually.

Installation Notes

External retaining rings require the correct retaining ring pliers or an installation tool sized for the ring diameter — improper tools can distort the ring and reduce holding force. Power down and de-energize the assembly before disassembly or installation. Ensure the shaft groove dimensions match the ring specifications before installation; groove depth and width tolerances directly affect ring retention. Inspect the groove and shaft for burrs or damage before seating the ring.
