Rotor Clip HO-43ST Pa Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-43ST PA is a heavy-duty internal snap retaining ring designed to secure components within a bore and prevent axial movement in assembled machinery. Manufactured from 1060/1090 spring steel with a phosphate finish, this ring fits a 7/16 inch bore diameter and provides a thrust load capacity of 1,238 pounds at the ring safety factor and 440 pounds at the groove safety factor. With a ring thickness of 0.025 inches and a free outer diameter of 0.482 inches, it is suited for precision retention applications in industrial assemblies, mechanical drives, and general fastening systems. Licensed machinists, maintenance technicians, and mechanical assemblers are the typical installers of this component.

This retaining ring is used in applications requiring reliable internal bore retention across a wide range of mechanical systems, including industrial machinery, automotive assemblies, and power transmission equipment. It installs into a groove with a width of 0.029 inches and a depth of 0.012 inches. The phosphate finish provides corrosion resistance suitable for general-purpose indoor and light industrial environments. This ring is sold individually but requires a minimum order quantity of 100 units.

Key Features

• Internal snap ring design retains components axially within a 7/16 inch bore
• Spring steel construction (SAE 1060/1090) provides consistent snap force and long service life
• Phosphate finish offers corrosion resistance for general-purpose applications
• Thrust load capacity of 1,238 pounds (ring safety factor) and 440 pounds (groove safety factor)
• Rockwell 30N hardness rating of 69.5 to 73 for reliable performance under load
• Meets ISO 13485.2016 and SAE 1060-1090 standards

Compatibility

Designed as an OEM-style internal retaining ring replacement for bores measuring 7/16 inch in diameter with a groove width of 0.029 inches and groove depth of 0.012 inches, consistent with standard internal snap ring groove specifications.

Installation Notes

Installation of internal snap retaining rings requires snap ring pliers sized for internal rings; use of incorrect tools can distort the ring and compromise retention. Power down and de-energize any equipment before disassembly and ring installation. Verify that bore groove dimensions match the ring specifications before installation to ensure proper seating and load capacity. Follow applicable industry standards and equipment manufacturer guidelines during assembly.
