Rotor Clip KG-212ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-212ST OIL is a steel internal spiral retaining ring designed for use in bored housings and assemblies where a secure axial retention method is required. With a 2.125-inch bore diameter and a free outside diameter of 2.267 inches, this ring seats into a machined groove to hold components in place without fasteners. Ring thickness is 0.078 inches and groove width measures 0.086 inches. The oil finish provides baseline corrosion resistance during storage and installation. This part is installed by machinists, maintenance technicians, and assemblers working in industrial, mechanical, and OEM equipment applications.

This internal spiral retaining ring is suited for use in housings, gearboxes, pumps, motors, and general mechanical assemblies requiring reliable axial load retention. The groove accepts a 0.086-inch width with a 0.063-inch depth. Thrust load capacity is rated at 21,870 pounds at the ring safety factor and 9,460 pounds at the groove safety factor, making it appropriate for moderate-to-heavy load retention in production and maintenance environments. Minimum order quantity is 5 units.

Installation Notes

This ring is installed by qualified mechanical assemblers or maintenance technicians. Power down and de-energize any equipment fully before disassembling housings or bearing bores. Use an appropriate spiral ring installation tool or pick to seat the ring fully into the groove — do not force or deform the ring during installation. Verify groove dimensions match the specified width and depth before installation to ensure proper seating and full load capacity.
