Rotor Clip SH-300ST Pa External Snap Retaining Ring 3 in

Product Description

The ROTOR CLIP SH-300ST PA is an external snap retaining ring designed to secure components on a 3-inch shaft by seating in a precision-cut external groove. Manufactured from 1060-1090 grade spring steel with a phosphate finish, this ring delivers reliable axial retention under mechanical load. It measures 0.093 inches in ring thickness and seats in a groove measuring 0.103 inches wide and 0.081 inches deep. The phosphate coating provides baseline corrosion resistance and lubricity for installation. Maintenance technicians, millwrights, and mechanical assemblers working on industrial shafts, gearboxes, pumps, and rotating assemblies will encounter this ring type in standard repair and build workflows.

This retaining ring is suited for use in industrial and commercial mechanical assemblies where a 3-inch nominal shaft diameter is present. Typical applications include pump shafts, motor shafts, gearbox assemblies, and other rotating equipment requiring positive axial component retention. The phosphate finish makes it appropriate for moderately demanding environments where a light protective coating is acceptable. It is sold individually with a minimum order quantity of 10 units per order.

Installation Notes

Installation and removal of external snap retaining rings should be performed by qualified mechanical technicians using appropriate snap ring pliers rated for the ring size. Always de-energize and lock out the equipment per OSHA lockout-tagout procedures before servicing any rotating shaft assembly. Ensure the shaft groove is clean and free of burrs before seating the ring. Wear appropriate eye protection, as snap rings can release under tension during installation or removal.
