Rotor Clip KG-62SJ Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-62SJ is a stainless steel internal spiral retaining ring designed to secure components within a bored housing without the need for fasteners or welding. Manufactured from AISI 302 stainless steel, it seats into a machined internal groove to provide axial retention against thrust loads. The ring carries a thrust load capacity of 3,160 pounds at the ring safety factor and 880 pounds at the groove safety factor. With a bore diameter of 5/8 inch and a ring thickness of 0.035 inches, this part suits precision assemblies where space is limited and corrosion resistance is required. Installation is performed by mechanical or industrial assembly technicians across a wide range of industries.

This internal spiral retaining ring is suited for use in bored housings found in motors, gearboxes, pumps, valves, and other rotary or linear assemblies that require reliable axial component retention. The 302 stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or elevated humidity where carbon steel rings would corrode. It is used in both light industrial and commercial equipment applications where an internal groove is machined to the specified dimensions.

Key Features

• AISI 302 stainless steel construction for corrosion resistance in demanding environments
• Internal spiral design provides axial retention without requiring a split or gap in the ring
• Thrust load capacity of 3,160 pounds at the ring safety factor and 880 pounds at the groove safety factor
• Bore diameter of 5/8 inch with a free outside diameter of 0.675 inches
• Ring thickness of 0.035 inches with a tolerance of -0.002 to 0.002 inches
• Meets AISI 302, AMS-5866, and ISO 13485:2016 standards

Compatibility

Designed as an OEM-style replacement or new-installation internal retaining ring for bored housings with a 5/8-inch bore diameter machined to the specified groove dimensions.

Installation Notes

Installation is typically performed by mechanical assembly technicians using spiral ring installation pliers or a suitable mandrel tool. The mating housing groove must be machined to the correct width and depth tolerances before ring insertion. Ensure the bore and groove are free of burrs, debris, and contaminants prior to installation. Verify groove dimensions match the specified groove width of 0.039 inches and groove depth of 0.020 inches to achieve rated load performance.
