The ROTOR CLIP KG-500SJ is a heavy-duty internal spiral retaining ring designed for large-bore applications requiring reliable axial retention. Manufactured from AISI 302 stainless steel, this ring seats into a machined internal groove to secure components against axial movement without requiring a separate fastener. The KG-500SJ is suited for rotating or static assemblies where corrosion resistance and high thrust load capacity are critical. With a bore diameter of 5 inches, a ring thickness of 0.111 inches, and a groove width of 0.12 inches, this ring is dimensioned for precision-fit installations. Mechanical technicians, maintenance professionals, and OEM assembly teams commonly install this type of retaining ring in pumps, gearboxes, motors, and hydraulic housings.
The KG-500SJ is intended for use in industrial and OEM applications where a 5-inch internal bore diameter is present and a spiral-style retaining ring is specified. Spiral retaining rings are commonly selected over stamped rings when uniform load distribution around the groove perimeter is required. The stainless steel construction makes this ring appropriate for wet, washdown, or mildly corrosive environments. A thrust load capacity of 45,950 pounds at the groove safety factor and 69,740 pounds at the ring safety factor indicates suitability for high-load bearing and shaft-assembly applications.
Designed as an OEM-style internal spiral retaining ring for any assembly with a 5-inch bore diameter groove machined to a width of 0.12 inches and a depth of 0.13 inches, with groove diameter tolerance of -0.006 to +0.006 inches.
Installation and removal of internal spiral retaining rings at this bore size should be performed using appropriately sized spiral ring pliers or installation tools to avoid deforming the ring. Shut down and de-energize all associated equipment before servicing any assembly containing this ring. Verify groove dimensions and tolerances against the ring specifications prior to installation to ensure proper seating and load transfer. This type of component is typically installed by mechanical or maintenance technicians following OEM assembly drawings or machine maintenance documentation.
