Rotor Clip SH-250ST Zd External Retaining Ring 2-1/2 in

Product Description

The ROTOR CLIP SH-250ST ZD is an external retaining ring designed to secure components on shafts in precision mechanical assemblies. It fits a 2.5-inch shaft diameter and seats into a groove that measures 2.36 inches in diameter and 0.086 inches wide. The ring is manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating for corrosion resistance. With a hardness rating of 47-52 HRC, this ring provides reliable axial retention under load. Mechanical assemblers, maintenance technicians, and industrial tradespeople install this ring wherever shaft-mounted components require a positive stop or retention point.

This external retaining ring is suited for use on 2.5-inch shafts in industrial and mechanical equipment, including pump assemblies, gearboxes, motors, and drive components. It is installed into a precision-machined external groove on the shaft. The ring conforms to SAE 1060-1090 and UNS G10600-G10900 standards and is produced to ISO 13485:2015 quality management requirements, making it appropriate for demanding mechanical and instrumentation applications. It is sold in a minimum order quantity of 5 units.

Installation Notes

External retaining rings of this type are installed and removed using retaining ring pliers sized for the ring gap; do not substitute flat-blade tools that could deform the ring or damage the groove. Relieve all shaft loads and de-energize or lock out any rotating machinery before servicing. Inspect the shaft groove for burrs, wear, or out-of-tolerance dimensions prior to seating the ring. Follow applicable ASME and employer safety standards for mechanical fastener installation.
