Rotor Clip KG-100SJ Internal Spiral Retaining Ring 1 in

Product Description

The ROTOR CLIP KG-100SJ is a stainless steel internal spiral retaining ring engineered for retention applications requiring a secure axial hold within a bored housing. Manufactured from AISI 302 stainless steel to AMS-5866 standards, it delivers strong corrosion resistance alongside reliable mechanical performance. The ring seats into a machined internal groove and provides a thrust load capacity of 2,330 pounds at the groove safety factor and 6,070 pounds at the ring safety factor. With a ring thickness of 0.042 inches and a groove width of 0.046 inches, the KG-100SJ is sized for precise, low-profile retention without requiring special tooling beyond standard spiral ring pliers.

This internal spiral retaining ring is suited for use in rotating assemblies, hydraulic components, gearboxes, pumps, and similar industrial or mechanical systems where a 1-inch bore diameter housing requires positive axial retention. Its spiral design allows single-turn installation and removal without the ear snags associated with stamped rings, making it a practical choice in tight-bore assemblies common in fluid power, precision machinery, and HVAC drive components. Machinists, millwrights, and mechanical technicians typically install this type of ring during assembly or field service operations.

Key Features

• Groove width of 0.046 inches with tolerance of 0.000 to 0.003 inches for consistent seating
• Meets AMS-5866 and ISO 13485:2016 standards

Compatibility

Designed as an OEM-style internal spiral retaining ring for housings with a 1-inch bore diameter requiring a standard groove width of 0.046 inches and groove depth of 0.033 inches.

Installation Notes

Installation and removal should be performed by a qualified technician using spiral retaining ring pliers appropriate for internal rings. De-energize and lock out all equipment before disassembling any assembly containing this ring. Verify groove dimensions match the specified groove width and depth tolerances before installation, as an undersized or oversized groove will reduce load capacity. Do not reuse a ring that has been overstressed or visibly deformed.
