The ROTOR CLIP KG-400ST OIL is a steel internal spiral retaining ring designed for bore applications requiring a secure, groove-seated fastening solution. Built from SAE 1060-1090 carbon steel with an oil finish, this ring seats into an internal groove to retain components along a shaft or within a bore. It is used by mechanical assemblers, maintenance technicians, and industrial tradespeople working on rotating equipment, assemblies, and machinery requiring reliable axial retention without secondary hardware.
This ring is suited for applications where a 4-inch bore diameter is specified and precise groove fitment is critical. The oil finish provides corrosion inhibition during storage and initial installation. With a thrust load capacity of 33,930 pounds at the groove safety factor and 55,800 pounds at the ring safety factor, this retaining ring handles demanding load conditions in industrial and mechanical service environments.
Designed for internal groove installations with a 4-inch bore diameter and a groove width of 0.12 inches. Groove diameter tolerance is -0.0060 to 0.0060 inches. Verify groove dimensions against application engineering specifications before installation.
Installation should be performed by qualified mechanical technicians familiar with retaining ring tooling and internal groove applications. Power down and de-energize any equipment before disassembly or ring installation. Use appropriate spiral retaining ring installation tools to seat the ring fully into the groove without distorting the ring profile. Confirm groove dimensions comply with the specified tolerances prior to installation to ensure proper axial retention and load performance.
