Rotor Clip SH-59ST Pa External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-59ST PA is an external snap retaining ring designed to secure components on a shaft by seating into a machined groove. Built from SAE 1060-1090 spring steel with a phosphate finish for corrosion resistance, this ring fits a 19/32 inch (0.5938 inch) shaft diameter with a groove diameter of 0.559 inches. With a hardness rating of 66-71 HRC, the ring maintains holding strength under mechanical load. Maintenance technicians, millwrights, and assemblers working on rotating or reciprocating shaft assemblies install this type of ring as a standard axial-retention fastener.

This external retaining ring is suited for shaft assemblies in HVAC equipment, pump drives, motor assemblies, and general mechanical systems where a reliable, low-profile axial stop is required. The phosphate finish provides a base layer of surface protection appropriate for indoor and sheltered mechanical environments. The ring is packaged individually with a minimum order quantity of 100 units, making it appropriate for production assembly lines, repair shops, and maintenance inventory programs.

Installation Notes

External snap rings of this type are installed and removed using retaining ring pliers sized for external rings — do not use substitute tools that may distort the ring or damage the groove. Relieve all mechanical load and de-energize equipment before servicing shaft assemblies. Confirm groove diameter, groove width, and groove depth match the ring specifications before installation to ensure proper seating and retention. Verify the ring is fully seated in the groove before returning equipment to service.
