Rotor Clip KG-225SJ Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-225SJ is a stainless steel internal spiral retaining ring designed to seat in a machined groove inside a bore and retain components axially without requiring a dedicated shoulder or snap groove. With a 2.25-inch bore diameter and a free outside diameter of 2.399 inches, this ring installs by coiling into the groove under its own spring tension. Ring thickness measures 0.078 inches and the groove width is 0.086 inches. Material is AISI 302 stainless steel, which provides corrosion resistance suitable for wet, chemical, or outdoor service environments. The part is installed by mechanical assemblers, maintenance technicians, and machinists working on rotating assemblies, pumps, and precision housings.

The KG-225SJ is used in applications requiring internal retention of shafts, bearings, pins, or other cylindrical components within a bored housing. The spiral design allows installation and removal without special pliers in many configurations, making it practical for field service and production assembly alike. Typical applications include pump and motor housings, gearboxes, pneumatic cylinders, and industrial equipment where stainless steel is specified for corrosion or cleanliness requirements. The groove depth of 0.066 inches and the inside diameter of 2.063 inches define the groove geometry required for proper seating.

Installation Notes

Installation is performed by qualified mechanical technicians or assemblers. The bore and groove dimensions must be verified against the ring specifications before installation to ensure proper retention and load capacity. De-energize and lock out all rotating or pressurized equipment before servicing any retaining ring. Spiral retaining rings are typically installed and removed using a flat-blade tool or spiral ring pliers; avoid overstressing the ring during installation to prevent deformation.
