Value Collection 79529574 External Snap Retaining Ring

Product Description

The VALUE COLLECTION 79529574 is an external snap retaining ring designed to secure components onto a shaft by seating into a machined groove on the shaft's outer diameter. Made from spring steel with a phosphate finish, this ring provides reliable axial retention in mechanical assemblies across industrial, HVAC, and general equipment applications. The shaft diameter is 1-5/16 inches, with a groove diameter of 1.232 inches and a ring thickness of 0.05 inches. The phosphate coating offers moderate corrosion resistance and improves lubrication retention during installation and service life.

This retaining ring is suited for use in rotating shaft assemblies, gear drives, motor shafts, bearing retention, and similar mechanical systems found in commercial and industrial equipment. It is typically installed by millwrights, maintenance technicians, and mechanical assemblers working on equipment requiring positive shaft retention without threaded fasteners. The package quantity is 10 rings per unit, making it practical for production or service environments where multiple installations are performed at once.

Compatibility

Designed as an OEM-style replacement or service ring for external snap ring grooves on shafts with a 1-5/16 inch nominal diameter in standard inch-measurement mechanical assemblies.

Installation Notes

External snap retaining rings require snap ring pliers with the correct tip size to spread the ring during installation and removal — do not attempt installation with makeshift tools, as improper spreading can permanently deform the ring. Ensure the shaft groove is free of burrs, debris, and corrosion before seating the ring. Always relieve any spring or mechanical load on the shaft assembly before removing or installing retaining rings to prevent ejection injury. Verify groove dimensions match the ring specifications before installation.
