Rotor Clip KG-112ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-112ST OIL is a steel internal spiral retaining ring designed for use in bores with a nominal diameter of 1-1/8 inches. The ring seats into a machined groove to retain components such as bearings, bushings, and shafts within a housing. Manufactured from 1060/1090 grade carbon steel with an oil finish for corrosion inhibition, this ring carries a thrust load capacity of 2860 pounds at the groove safety factor and 7420 pounds at the ring safety factor. Ring thickness measures 0.05 inches with a tolerance of -0.002 to 0.002 inches. Machinists, maintenance technicians, and assembly professionals install this ring where a permanent or semi-permanent internal retention method is required.

This internal spiral retaining ring is suited for industrial and mechanical assemblies where bore retention is needed without a fastener or threaded feature. Typical applications include gearboxes, hydraulic cylinders, electric motor housings, and general machinery where axial component retention is critical. The oil finish makes it appropriate for use in lightly lubricated environments or where parts are stored before installation. It installs without special tooling in most standard groove configurations that match its groove width of 0.056 inches and groove depth of 0.036 inches.

Compatibility

Designed as an OEM-style internal spiral retaining ring for bores with a 1-1/8 inch nominal diameter and a groove width of 0.056 inches with a groove depth of 0.036 inches, consistent with standard retaining ring groove specifications for this bore size.

Installation Notes

Installation is typically performed by maintenance technicians and mechanical assemblers. Confirm that the bore groove dimensions match the ring specifications before installation. Clean and inspect the groove for burrs or damage prior to seating the ring. Verify that the bore and mating components are free of debris to ensure proper ring seating and full thrust load capacity.
