It fits a 13\/16-inch (0.8125-inch) shaft diameter with a groove diameter of 0.762 inches and a ring thickness of 0.042 inches. Manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, this ring delivers solid corrosion resistance and a hardness of 66-71 HRC. Mechanical assemblers, maintenance technicians, and industrial tradespeople install these rings in a wide range of rotating and static shaft assemblies across commercial and industrial equipment.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is suited for use in shaft assemblies where a reliable, low-profile axial fastener is required. It applies in manufacturing, HVAC mechanical assemblies, pump and motor shafts, and general industrial maintenance applications. The ring seats in a groove that is 0.046 inches wide and 0.025 inches deep, providing a stable retention profile. Its free outside diameter of 1.15 inches and free diameter of 0.751 inches allow for controlled installation using standard retaining ring pliers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 13\/16-inch (0.8125-inch) shaft diameter with 0.762-inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 carbon steel construction with yellow zinc dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHardness rating of 66-71 HRC for durable axial load retention\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.042 inches with groove width of 0.046 inches for precise seating\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 1060-1090 and UNS G10600-G10900 fastener standards\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units — suitable for maintenance stock and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 13\/16-inch shaft diameters with a standard groove profile; verify groove diameter, width, and depth against shaft specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical technicians using external retaining ring pliers sized for the ring's lug holes. De-energize and lock out all equipment before servicing any shaft assembly. Ensure the shaft groove dimensions match the ring specifications — groove diameter, width, and depth — before seating the ring. Do not reuse a retaining ring that has been removed, as the material may have been stressed beyond its design limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 13\/16 inches (0.8125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.762 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: 0.751 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.15 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: 0.025 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: SAE 1060-1090 Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1060\/1090\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 66-71 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Yellow Zinc Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 1060-1090, UNS G10600-G10900, ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: SH-81ST ZD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51709295034674,"sku":"SH-81ST ZD","price":3009.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34331e50a8ad745e1a46c29a2b722493_d049fb6f-d405-4c3b-837f-5c4f25010b4b.jpg?v=1788454111","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-81st-zd-external-retaining-ring-13-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
