Electro Hardware HO-237ST PD-15 Internal Snap Ring 2-3/8 in

Product Description

The ELECTRO HARDWARE HO-237ST PD-15 is an internal snap retaining ring designed for bore-mounted applications requiring a secure, low-profile retention solution. Made from spring steel with a phosphate finish, this ring seats into a machined groove inside a bore to hold shafts, pins, bearings, and assemblies in axial position. The bore diameter is 2-3/8 inches with a free outside diameter of 2.63 inches. Ring thickness measures 0.078 inches. The phosphate finish provides baseline corrosion resistance and lubricity. Installation and removal are performed by licensed mechanics, millwrights, or maintenance technicians using standard snap ring pliers.

This retaining ring is suited for use in industrial equipment, mechanical assemblies, gearboxes, pumps, and similar applications where internal bore retention is required. The 2-3/8 inch nominal size fits a standard bore diameter, making it a common replacement or service part across a range of rotating and stationary mechanical assemblies. The package quantity is 1 ring, with a minimum order quantity of 15 units.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using internal snap ring pliers sized for the ring gap. De-energize and lock out all equipment before beginning any retaining ring service. Inspect the bore groove for burrs or wear before seating the ring to ensure full engagement. Do not over-expand the ring during installation, as spring steel can fracture if deformed beyond its design limit.
