Rotor Clip KG-175ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-175ST OIL is a steel internal spiral retaining ring designed for a 1.75-inch bore diameter. It seats into a machined internal groove to retain components on shafts or within housings without requiring secondary fasteners. The ring is finished in oil to resist corrosion during storage and service. At 0.062 inches thick with a free outside diameter of 1.876 inches, it is sized for precision groove engagement in medium-load mechanical assemblies. Machinists, millwrights, and maintenance technicians working on rotating equipment, gearboxes, pumps, and similar assemblies install this type of ring as a standard internal retainer.

This ring is suited for use in industrial and commercial mechanical assemblies where a reliable internal groove retainer is required. Typical applications include pump housings, gear assemblies, motor end-bells, and hydraulic cylinder bores where axial retention of bearings, bushings, or other seated components is needed. The oil finish makes it appropriate for environments where bare steel would be exposed to moisture or light contaminants during the installation period.

Installation Notes

Installation and removal of internal spiral retaining rings requires appropriate snap ring pliers or spiral ring installation tools sized for the bore diameter. Always de-energize, depressurize, and lock out the equipment before servicing any assembly containing retaining rings. Verify groove dimensions match the ring specifications before installation to avoid improper seating or reduced load capacity. Follow applicable ANSI and OSHA machine safety standards during disassembly and reassembly.
