Rotor Clip KG-250ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-250ST OIL is a steel internal spiral retaining ring designed for a 2.5-inch bore diameter. It seats in a machined internal groove to axially retain shafts, pins, or bearings inside bores without requiring additional fasteners. The ring is manufactured from SAE 1060-1090 steel with an oil finish for corrosion resistance during storage and service. Key dimensions include a 2.667-inch free outside diameter, 0.086-inch groove width, and 0.078-inch ring thickness. Machinists, maintenance technicians, and mechanical assemblers install this ring in industrial and OEM applications where reliable axial retention is required inside a housing or bore.

This internal spiral retaining ring is used in mechanical assemblies requiring axial retention within a 2.5-inch bore. Typical applications include gearboxes, motors, pumps, cylinders, and general industrial machinery. The spiral design allows installation and removal without specialized snap-ring pliers in many configurations, making it practical for production assembly and field service. It is sold individually with a minimum order quantity of 5 units.

Compatibility

Designed for use in any housing or bore machined to accept a 2.5-inch internal spiral retaining ring with a 0.086-inch groove width and 0.074-inch groove depth per ROTOR CLIP KG-series specifications.

Installation Notes

Installation is performed by mechanical technicians or assemblers during equipment build or overhaul. Ensure the bore groove is machined to the specified width and depth tolerances before installation. Clean the groove of debris and apply a light oil film if required by the application. Do not over-stress the ring during installation by exceeding its elastic range, as permanent deformation will compromise axial retention.
