It seats into a machined groove with a 1.059 inch groove diameter and holds components axially without requiring a second groove or backing device. Ring thickness is 0.05 inches and groove width is 0.056 inches, making it suitable for compact shaft assemblies where space is limited. The ring is manufactured from AISI 302 stainless steel per AMS-5866 and meets ISO 13485:2016 quality management standards, which makes it appropriate for applications requiring documented material traceability. Machinists, maintenance technicians, and assemblers working on rotating or reciprocating shaft assemblies typically install this type of ring.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is used in light- to medium-duty shaft assemblies across industrial, mechanical, and equipment manufacturing applications. The external spiral design eliminates the need for installation tooling in many configurations, allowing the ring to be wound onto the shaft groove directly. It is well-suited for medical device assemblies, instrumentation, and other precision applications where ISO 13485:2016 material conformance is a requirement. The 302 stainless construction also provides corrosion resistance in mildly wet or chemically exposed environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal spiral design fits 1-1\/8 inch shaft diameter without requiring snap-ring pliers in most installations\u003c\/li\u003e\n  \u003cli\u003eAISI 302 stainless steel construction per AMS-5866 provides corrosion resistance and documented material traceability\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 13485:2016 quality management standards, supporting use in medical device and precision instrument assemblies\u003c\/li\u003e\n  \u003cli\u003eGroove diameter of 1.059 inches with a tolerance of -0.004 to +0.004 inches for consistent seating\u003c\/li\u003e\n  \u003cli\u003eOil finish coating aids installation and provides light surface protection\u003c\/li\u003e\n  \u003cli\u003eFree outside diameter of 1.253 inches allows visual confirmation of proper groove engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external spiral retaining ring for 1-1\/8 inch shafts with a machined groove diameter of 1.059 inches, groove width of 0.056 inches, and groove depth of 0.033 inches. Verify shaft and groove dimensions against the stated tolerances before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical assembler familiar with retaining ring specifications and shaft tolerance requirements. Verify that the shaft groove dimensions match the ring specifications before installation, and inspect the groove for burrs or damage that could affect seating. Spiral retaining rings are wound onto the shaft groove and should never be over-stressed or forced into an undersized groove. Remove the ring before disassembly of shaft components to avoid damage to the ring or groove.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: External Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 1.059 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.004 to +0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 1.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.013 to 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.253 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.056 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to +0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.033 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 302 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Standards\u003c\/strong\u003e: AISI 302, AMS-5866\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuality Standard\u003c\/strong\u003e: ISO 13485:2016\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00557 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: CG-112SJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51723172708658,"sku":"CG-112SJ","price":2243.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a69c0aa71c152307354dd1c5168e00_dbccbff3-1dbd-4ef5-9f27-2a5caf2f4754.jpg?v=1788601592","url":"https:\/\/voomisupply.com\/products\/rotor-clip-cg-112sj-external-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
