It seats into a machined internal groove to retain shafts, pins, bearings, or other components within a housing or bore. The ring is manufactured from AISI 302 stainless steel, providing corrosion resistance in demanding industrial and mechanical environments. With a ring thickness of 0.078 inches and a groove width of 0.086 inches, the KG-250SJ is dimensionally precise and suited for applications requiring a secure, low-profile axial retention solution. Installation and removal require no special pliers beyond standard spiral ring tools.\u003c\/p\u003e\u003cp\u003eThis retaining ring is used in mechanical assemblies where an internal groove is machined into a bore to provide axial retention without threading or welding. Typical applications include pump housings, gearboxes, hydraulic cylinders, and industrial machinery where a 2.5-inch bore is present. The stainless steel construction makes it appropriate for wet, washdown, or mildly corrosive service environments. Machinists, maintenance technicians, and assembly professionals working in general industrial, fluid handling, or OEM equipment contexts regularly specify this ring type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal spiral design seats in a machined groove inside a 2.5-inch bore\u003c\/li\u003e\n\u003cli\u003eAISI 302 stainless steel construction meets AMS-5866 material standard\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.086 inches with a tolerance of 0.000 to 0.005 inches for precise fit\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.078 inches with a tolerance of -0.003 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003eThrust load capacity of 13,080 lb (groove safety factor) and 25,730 lb (ring safety factor)\u003c\/li\u003e\n\u003cli\u003eComplies with ISO 13485:2016 and AISI 302 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style internal spiral retaining ring for mechanical assemblies with a 2.5-inch bore diameter and a machined internal groove matching the specified groove width and depth dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician using spiral retaining ring installation tools appropriate for the bore diameter. Verify that the internal groove dimensions in the housing match the specified groove width of 0.086 inches and groove depth of 0.074 inches before installation. Ensure the bore and groove are clean and free of debris prior to seating the ring. Confirm full ring engagement in the groove before applying any axial load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 2.667 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.267 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.078 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: 0.086 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: 0.074 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.006 to 0.006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity\u003c\/strong\u003e: 13,080 lb (groove safety factor) \/ 25,730 lb (ring safety factor)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: AISI 302\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 302, AMS-5866, ISO 13485:2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.036 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-250SJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51693072548146,"sku":"KG-250SJ","price":1506.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a69c0aa71c152307354dd1c5168e00_28bc6c16-3246-49fc-b593-4cfa46d9891f.jpg?v=1788306951","url":"https:\/\/voomisupply.com\/products\/rotor-clip-kg-250sj-internal-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
