Manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating for corrosion resistance, this ring measures 0.468 inches in groove diameter and 0.035 inches in ring thickness. Hardness is rated at 66-71 HRC, making it suitable for applications that demand consistent spring-back and reliable seating under load. Machinists, assemblers, and maintenance technicians working in industrial and mechanical assembly environments install this type of ring using standard snap-ring pliers.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is used wherever a shaft-mounted component must be locked axially in place, including gear assemblies, motor shafts, pump impeller stacks, conveyor systems, and general mechanical subassemblies. It fits shafts with a nominal diameter of 1\/2 inch (0.500 inches) and is intended for installation into a groove with a width of 0.039 inches and a depth of 0.016 inches. The zinc dichromate finish provides a baseline level of corrosion protection suitable for indoor or lightly protected environments. This part is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production or MRO stocking programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal design seats in shaft groove for reliable axial component retention\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 carbon steel construction with hardness of 66-71 HRC\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish provides corrosion resistance for standard service environments\u003c\/li\u003e\n  \u003cli\u003eGroove diameter of 0.468 inches with a tolerance of -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.035 inches with a tolerance of -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 1\/2-inch diameter shafts (0.500 inches nominal) requiring an external retaining ring groove with a width of 0.039 inches and a depth of 0.016 inches per SAE and UNS G10600-G10900 groove specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires external snap-ring pliers sized for a 1\/2-inch shaft ring. Verify that the shaft groove dimensions match the ring specifications before installation, and inspect the groove for burrs or damage that could prevent proper seating. De-energize and lock out any machinery before servicing components retained by this ring. Do not over-spread the ring during installation, as exceeding the elastic limit of the material will compromise retention force and require ring replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.468 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.461 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.005 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.039 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: 0.016 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.035 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\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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-50ST ZD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51693501350194,"sku":"SH-50ST ZD","price":1718.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34331e50a8ad745e1a46c29a2b722493_57909467-2de3-4cb7-a93b-bcf48291ae65.jpg?v=1788313278","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-50st-zd-external-retaining-ring-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
