Value Collection 75941989 External Snap Retaining Ring

Product Description

The VALUE COLLECTION 75941989 is an external snap retaining ring designed to secure components onto shafts by seating into a precision-machined groove. Made from spring steel with a phosphate finish for corrosion resistance, this ring fits a 9/16 inch shaft diameter with a groove diameter of 0.530 inches. The phosphate coating provides a base layer of protection suitable for general industrial and mechanical assembly applications. It is installed and removed by machinists, maintenance technicians, and assembly professionals using standard snap ring pliers.

This retaining ring is suited for use in light machinery, power transmission assemblies, automotive components, and general industrial equipment where an external shaft-mounted retaining feature is required. The ring package quantity of 20 per unit makes it practical for bench stock or small-scale assembly operations. Typical applications include bearing retention, gear and pulley positioning, and securing other rotating or sliding components on shafts.

Compatibility

Designed as an external snap retaining ring for 9/16 inch diameter shafts with a groove diameter of 0.530 inches; verify groove width and ring thickness tolerances against shaft specifications before installation.

Installation Notes

Installation and removal require external snap ring pliers sized for the ring diameter; using incorrect tooling risks deforming the ring or damaging the groove. Always relieve any load or tension on the shaft assembly before installing or removing the ring. Confirm groove dimensions match the ring specifications to ensure proper seating and axial retention. Worn or distorted rings should be replaced rather than reused.
