It seats in a machined groove to hold shafts, bearings, or assemblies in place without requiring threaded fasteners or welding. The ring has a 3.75-inch bore diameter, a free outer diameter of 4.002 inches, and a ring thickness of 0.111 inches. Manufactured from 1060\/1090 grade steel with an oil finish for corrosion resistance, this ring is installed by machinists, maintenance technicians, and mechanical assemblers working with precision-fitted bore applications.\u003c\/p\u003e\u003cp\u003eThis internal spiral retaining ring is suited for industrial and mechanical assembly applications where a reliable axial retention method is required within a housing or bore. It fits into a groove with a width of 0.12 inches and a depth of 0.112 inches. The oil finish makes it appropriate for environments with light lubrication or moderate moisture exposure. It is typically used in gearboxes, pumps, motors, and similar rotating or reciprocating machinery where bore retention is necessary.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal spiral design seats directly into a machined bore groove for tool-free retention of shafts and assemblies\u003c\/li\u003e\n\u003cli\u003e3.75-inch bore diameter with a 4.002-inch free outer diameter for precise fitment\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.111 inches with a tight tolerance of plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.12 inches and groove depth of 0.112 inches for defined seating geometry\u003c\/li\u003e\n\u003cli\u003eThrust load capacity of 29,690 pounds at groove safety factor and 52,310 pounds at ring safety factor\u003c\/li\u003e\n\u003cli\u003eOil finish on 1060\/1090 steel provides light corrosion resistance suitable for lubricated assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in bores requiring an internal spiral retaining ring with a 3.75-inch bore diameter, a 0.12-inch groove width, and a 0.112-inch groove depth machined to standard tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly machined groove meeting the specified width and depth tolerances before the ring is seated. Use the appropriate spiral ring installation tool to avoid deforming the ring during assembly. Ensure all rotating machinery is fully de-energized and locked out before servicing components that use this retaining ring. Inspect the groove for burrs or surface damage prior to installation to prevent improper seating or premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outer Diameter\u003c\/strong\u003e: 4.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.003 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.112 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0060 to 0.0060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Groove Safety Factor)\u003c\/strong\u003e: 29,690 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Ring Safety Factor)\u003c\/strong\u003e: 52,310 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1060\/1090\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Spiral Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 1060-1090; UNS G10600-G10900; ISO 13485:2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.119 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROTOR CLIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KG-375ST OIL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51714131198258,"sku":"KG-375ST OIL","price":1669.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a545ce7de19f57e4c6511ca340ebec8_f6db863c-97d1-47d6-8b2a-7579b5b0ed08.jpg?v=1788496656","url":"https:\/\/voomisupply.com\/products\/rotor-clip-kg-375st-oil-internal-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
