Rotor Clip HO-37ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-37ST ZD is an internal snap retaining ring designed to secure components within a bored housing or assembly. Manufactured from 1060/1090 spring steel with a zinc finish, this ring seats in a machined internal groove to prevent axial movement of shafts, pins, and other retained parts. It carries a thrust load capacity of 1066 pounds at the ring safety factor and 350 pounds at the groove safety factor. The ring measures 0.025 inches thick with a free outer diameter of 0.025 inches and fits a 0.375-inch bore diameter. Installation and removal are performed by maintenance technicians and mechanical assemblers using standard snap ring pliers.

This internal retaining ring is suited for light mechanical assemblies, precision bore applications, and production environments where consistent groove geometry is required. The zinc finish provides corrosion resistance in general industrial environments. With a groove width of 0.029 inches and groove depth of 0.011 inches, it fits standard internal groove profiles machined to SAE 1060-1090 and ISO 13485.2016 specifications. It is sold individually with a minimum order quantity of 100 units, making it appropriate for production-line procurement or maintenance stock.

Compatibility

Designed as an OEM-style internal retaining ring for 0.375-inch bore diameter applications with a machined internal groove; verify groove width and depth dimensions against the specifications listed before installation.

Installation Notes

Installation and removal require snap ring pliers sized for internal rings; using incorrect tooling can distort the ring and reduce retention capacity. Power down and de-energize any equipment before disassembling the bore assembly. Inspect the groove for burrs or damage before seating the ring. Follow applicable machine safety standards and the equipment manufacturer's service procedures during assembly.
