Value Collection 79529640 External Snap Retaining Ring

Product Description

The VALUE COLLECTION 79529640 is an external snap retaining ring designed to secure components on shafts in a wide range of mechanical assemblies. Manufactured from spring steel with a phosphate finish, this ring fits a 1-3/4 inch shaft diameter and seats in a groove measuring 1.65 inches in diameter and 0.068 inches in width. Ring thickness is 0.062 inches and free diameter is 1.618 inches. The phosphate coating provides a base layer of corrosion resistance and improves lubrication retention during installation. Machinists, maintenance technicians, and assembly professionals install this type of retaining ring as a reliable axial fastener in place of threaded hardware.

This external snap retaining ring is suited for use in general industrial and mechanical applications where a shaft-mounted component must be held in axial position. Typical applications include electric motor shafts, gearboxes, pump assemblies, and power transmission equipment. It is sized for a 1-3/4 inch nominal shaft and is packaged in a quantity of 5 rings per package, making it practical for bench stock or maintenance kits.

Installation Notes

External snap retaining rings should be installed and removed using proper snap ring pliers sized for external rings. Always wear eye protection during installation, as rings can release under tension. Ensure the shaft groove is clean and free of burrs before seating the ring. Confirm the ring is fully seated in the groove before returning the assembly to service.
