Rotor Clip KG-500ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-500ST OIL is a steel internal spiral retaining ring designed for precision bore retention in industrial assemblies. Built from SAE 1060-1090 high-carbon steel with an oil finish for corrosion resistance, it seats into an internal groove to secure shafts, bearings, and components against axial movement. The ring fits a 5-inch nominal bore with an inside diameter of 4.673 inches and a free outside diameter of 5.297 inches. Ring thickness is 0.111 inches. Groove width is 0.12 inches with a groove depth of 0.13 inches. Mechanical and maintenance technicians working on industrial machinery, pumps, and rotating equipment install this ring type as a standard fastening element.

This internal spiral retaining ring is suited for use in bore applications found in industrial equipment, gearboxes, pumps, motors, and heavy-duty rotating assemblies. The oil finish is appropriate for environments where mild corrosion protection is required during storage and service. The spiral design allows installation without special snap-ring pliers in many configurations, making it practical for high-volume assembly operations and field service scenarios. It is supplied individually and is appropriate for single-unit replacement or production assembly use.

Key Features

• Internal spiral ring design seats into a machined bore groove without lugs or ears
• Oil finish provides baseline corrosion protection for storage and service
• Thrust load capacity of 45,950 pounds at groove safety factor and 69,740 pounds at ring safety factor
• Groove width tolerance of 0.000 to 0.005 inches and ring thickness tolerance of -0.003 to 0.003 inches for precise fitment
• Conforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2016 material and dimensional standards
• Groove diameter tolerance of -0.006 to 0.006 inches for flexible bore compatibility

Compatibility

Designed as an OEM-style internal spiral retaining ring for 5-inch bore diameter applications in industrial rotating equipment and mechanical assemblies.

Installation Notes

Installation of internal spiral retaining rings is typically performed by mechanical technicians or maintenance personnel. De-energize and lock out all equipment per OSHA lockout/tagout procedures before servicing any assembly containing this ring. Verify bore groove dimensions against the specified groove width and depth before installation to ensure proper seating and load capacity. Do not reuse a ring that has been removed, as the spiral geometry may be compromised.
