Value Collection 79529723 External Snap Retaining Ring

Product Description

The VALUE COLLECTION 79529723 is an external snap retaining ring designed to secure components on shafts in mechanical assemblies. It seats in a machined groove on the outside diameter of a shaft, preventing axial movement of gears, bearings, pulleys, and similar parts. The ring is manufactured from spring steel with a phosphate finish for corrosion resistance and surface hardness. It fits a 1/2 inch shaft diameter with a groove diameter of 0.468 inches and a ring thickness of 0.035 inches. Machinists, maintenance technicians, and assembly workers install this type of ring across a wide range of industrial, HVAC, and mechanical service applications.

This retaining ring is suited for use in rotating shaft assemblies found in motors, pumps, blowers, and general mechanical equipment. The phosphate finish makes it appropriate for applications where mild corrosion resistance is needed without the cost of stainless hardware. It is sold in packages of 20, making it practical for bench stock or field service kits where multiple installations are anticipated.

Key Features

• Phosphate finish adds surface corrosion resistance and lubrication retention
• Groove width of 0.039 inches with a tolerance of 0.000 to 0.003 inches for precise fitment
• Ring thickness of 0.035 inches with a tolerance of -0.002 to 0.002 inches
• Package quantity of 20 pieces supports bench stock and multi-unit service jobs

Compatibility

Designed for use on 1/2 inch diameter shafts with a machined external groove measuring 0.468 inches in diameter and 0.039 inches in width. Verify groove dimensions against shaft specs before installation.

Installation Notes

External snap retaining rings are installed using snap ring pliers sized for external rings. Confirm the shaft groove is clean and free of burrs before seating the ring. Wear eye protection during installation, as the ring is under spring tension and can release unexpectedly. Do not reuse a ring that has been over-expanded or shows signs of deformation.
