Rotor Clip KG-237ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-237ST OIL is a steel internal spiral retaining ring designed for use in bored housings and assemblies requiring reliable axial retention. With a 2.375-inch bore diameter and a free outside diameter of 2.535 inches, this ring seats into a machined groove to secure components against axial movement. It is manufactured from 1060/1090 high-carbon steel with an oil finish that provides corrosion resistance during storage and service. At 0.078 inches thick, it delivers a thrust load capacity of 11,920 pounds at the groove safety factor and 24,440 pounds at the ring safety factor. Machinists, maintenance technicians, and assembly professionals install this ring in production and MRO environments.

This internal spiral retaining ring is suited for residential and industrial machinery, gearboxes, hydraulic assemblies, pumps, and other rotating equipment where a standard internal groove retains a shaft-mounted component. The spiral design allows installation and removal with standard retaining ring pliers without the need for ear-notch tooling. It is appropriate for any application calling for an internal ring with a 2.375-inch bore, a groove width of 0.086 inches, and a groove depth of 0.071 inches.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using retaining ring pliers sized for spiral internal rings. Confirm groove diameter, groove width, and groove depth match the specifications of this ring before installation. Clean and inspect the groove for burrs or damage prior to seating the ring. Always relieve any system pressure or stored energy and de-energize the assembly before disassembling the bore housing.
