Rotor Clip KG-131ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-131ST OIL is a steel internal spiral retaining ring designed to secure components within a bored housing by seating in a machined groove. Built from SAE 1060-1090 high-carbon steel with an oil finish for corrosion resistance, this ring targets a 1.3125-inch bore diameter. It measures 1.406 inches in free outside diameter, 0.05 inches in ring thickness, and requires a groove width of 0.056 inches and a groove depth of 0.042 inches. The oil finish lubricates the ring during installation and provides light protection in service. Machinists, maintenance technicians, and assembly professionals install this type of ring in shaft and housing assemblies across industrial and mechanical applications.

This internal spiral retaining ring is used in bored housings where a standard snap ring groove is machined to accept a spiral-wound retaining element. It is suited for residential and commercial mechanical assemblies including gearboxes, pump housings, motor end bells, and similar bore-retention applications. The spiral design allows installation without special snap-ring pliers in many configurations, making it practical for high-volume assembly and field repair situations. A minimum order quantity of 5 pieces applies to this part number.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician familiar with retaining ring applications. Verify that the housing groove dimensions match the specified groove width and depth before installation to avoid ring failure under load. De-energize and lock out any rotating or pressurized equipment before servicing the assembly. Do not reuse a retaining ring that has been removed, as repeated installation can alter ring geometry and reduce load capacity.
