Rotor Clip KG-375SJ Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-375SJ is an internal spiral retaining ring designed for use in bored housing applications where a secure axial component retention is required. Manufactured from AISI 302 stainless steel, this ring meets AMS-5866 and ISO 13485:2016 standards, making it appropriate for demanding industrial, medical, and mechanical assembly environments. It features a 3.75-inch bore diameter, a free outside diameter of 4.002 inches, and a ring thickness of 0.111 inches. The spiral design allows for tool-assisted installation and removal without the need for specialized snap-ring pliers used with standard stamped rings. Machinists, maintenance technicians, and mechanical assemblers are the typical installers.

This retaining ring is suited for use in housings, bores, and cylindrical components where an internal groove has been machined to the correct dimensions. It is appropriate for precision assemblies in industrial machinery, fluid power equipment, and medical devices where stainless steel corrosion resistance and dimensional consistency are required. The groove width of 0.12 inches and groove depth of 0.112 inches define the required housing groove profile. Thrust load capacity is rated at 29,690 pounds by groove safety factor and 52,310 pounds by ring safety factor.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician familiar with retaining ring assembly procedures. Power down and de-energize any equipment before servicing components that use this ring. Use the correct spiral retaining ring installation tool to seat the ring fully and evenly within the housing groove. Inspect the groove for burrs, debris, or out-of-tolerance dimensions before installation to avoid ring deformation or premature failure.
