Rotor Clip KG-225ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-225ST OIL is a steel internal spiral retaining ring designed for use in bores with a 2.25-inch diameter. This ring seats into a machined internal groove to retain components such as bearings, bushings, and shafts within a housing. It is manufactured from SAE 1060-1090 carbon steel with an oil finish, providing corrosion inhibition during storage and early service life. The ring measures 0.078 inches thick and accepts a groove width of 0.086 inches, with a free outside diameter of 2.399 inches. Installation and removal are performed by licensed mechanical trades, tooling shops, and assembly professionals working on rotating equipment, pumps, and gearboxes.

This internal spiral retaining ring is suited for precision mechanical assemblies where a continuous, multi-turn ring profile is required for consistent radial load distribution. The spiral design eliminates the ear protrusions found on standard snap rings, making it appropriate for installations where clearance around the ring face is limited. Typical applications include industrial pumps, electric motors, gearbox housings, hydraulic cylinders, and rotating shaft assemblies in both commercial and industrial settings.

Compatibility

Designed as an OEM-style internal spiral retaining ring for precision-machined housings with a 2.25-inch bore diameter and grooves dimensioned to accept a 0.086-inch groove width and 0.066-inch groove depth per spiral ring specifications.

Installation Notes

Installation is typically performed by qualified mechanical technicians or tooling professionals. De-energize and lock out all equipment before disassembly or ring installation in accordance with applicable OSHA lockout-tagout procedures. Use spiral retaining ring installation tools appropriate for the bore size to seat the ring evenly into the groove without deforming the ring profile. Inspect the groove dimensions for compliance with specified tolerances before installing the ring to ensure proper thrust load performance.
