This single-turn spiral ring seats into a machined external groove on a shaft to retain components axially without requiring a tang or ear cutout in the ring face. Manufactured from AISI 302 stainless steel to AMS-5866 specification, it offers good corrosion resistance for use in wet, chemical, or outdoor environments. The ring measures 0.042 inches thick with a groove diameter of 0.821 inches and a free outside diameter of 0.964 inches. Machinists, maintenance technicians, and mechanical assembly professionals work with this style of retaining ring in precision shaft and bearing assemblies.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for use in rotating shaft assemblies, pump components, motor shafts, and general industrial or commercial mechanical applications where an external groove retainer is required. The spiral design allows installation and removal without special snap ring pliers, using a simple push-on or tool-assisted slide method. The 302 stainless steel construction makes it appropriate for environments where carbon steel rings would face corrosion concerns, including food-processing adjacent equipment, marine hardware, and light chemical service assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal spiral design seats in a machined shaft groove for axial component retention without a tang gap in the ring face\u003c\/li\u003e\n  \u003cli\u003eAISI 302 stainless steel construction per AMS-5866 specification for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eShaft diameter: 0.875 inches; groove diameter: 0.821 inches\u003c\/li\u003e\n  \u003cli\u003eRing thickness: 0.042 inches; groove width: 0.046 inches; groove depth: 0.027 inches\u003c\/li\u003e\n  \u003cli\u003eOil finish applied; suitable for industrial assembly environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13485:2016 quality management standards\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 7\/8 inch shaft diameters with a machined external groove meeting the specified 0.821 inches groove diameter and 0.046 inches groove width dimensions.

Power down and de-energize any associated machinery before servicing shaft assemblies. Confirm the shaft groove dimensions match the ring tolerances prior to installation to prevent improper seating or ring failure under load. Do not reuse a ring that has been removed from service.\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: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.821 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.003 to +0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.814 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: 0.964 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to +0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.027 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.042 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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 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\u003eFinish\u003c\/strong\u003e: Oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00263 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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-87SJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51718279332146,"sku":"CG-87SJ","price":3235.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a69c0aa71c152307354dd1c5168e00_38eae347-43b5-4a62-929e-8fc826891331.jpg?v=1788551531","url":"https:\/\/voomisupply.com\/products\/rotor-clip-cg-87sj-external-spiral-retaining-ring-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
