Manufactured from SAE 1060-1090 spring steel with a cadmium finish, it seats into a 0.468-inch groove diameter and holds a ring thickness of 0.035 inches. The cadmium plating provides corrosion resistance in demanding service environments. Licensed trades and industrial maintenance technicians install this ring as a precision fastening element in rotating assemblies, drive shafts, and mechanical power-transmission systems. It meets military specification MS 16624-1050 and conforms to ISO 13485.2015 standards, making it suitable for applications with strict dimensional and materials traceability requirements.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring fits 1\/2-inch shafts in residential and commercial mechanical assemblies including HVAC blower motor shafts, pump assemblies, and general industrial drive components. It is sized for a 0.039-inch groove width and a 0.016-inch groove depth. Its free outside diameter of 0.77 inches and free diameter of 0.461 inches allow it to snap into properly machined grooves without secondary fasteners. Maintenance technicians and mechanical assemblers working on shaft-retained components select this ring when cadmium plating and military-spec compliance are required by the application or service specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal retaining ring style — mounts on shaft OD, no internal bore machining required\u003c\/li\u003e\n  \u003cli\u003eCadmium finish for corrosion resistance in harsh or humid service environments\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel with hardness of 66-71 HRC for consistent snap-fit retention force\u003c\/li\u003e\n  \u003cli\u003eMeets military specification MS 16624-1050 and ISO 13485.2015 for traceability-sensitive applications\u003c\/li\u003e\n  \u003cli\u003eGroove width tolerance of 0.0000 to 0.0030 inches supports tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eRing thickness tolerance of -0.0020 to 0.0020 inches ensures consistent seating depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service part for external retaining ring applications on 1\/2-inch shafts with a groove diameter of 0.468 inches, groove width of 0.039 inches, and groove depth of 0.016 inches per SAE 1060-1090 and MS 16624-1050 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExternal retaining rings require proper retaining ring pliers or snap-ring pliers sized for this ring diameter — do not use improvised tools that can distort the ring or damage the groove. De-energize and lock out all power to rotating equipment before removing or installing shaft retaining hardware per applicable OSHA lockout\/tagout procedures. Inspect the shaft groove for burrs, wear, or out-of-tolerance dimensions before installation, as an undersized or oversized groove will compromise retention force. Cadmium-plated parts should be handled with appropriate PPE per your facility safety program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inches, 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.468 inches (11.89 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.039 inches (0.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.0000 to 0.0030 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\u003eFree Diameter\u003c\/strong\u003e: 0.461 inches (11.71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.0050 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.035 inches (0.89 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: SAE 1060-1090 Spring Steel (UNS G10600-G10900)\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: Cadmium-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0009 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: MS 16624-1050\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\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 MCD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51714899542322,"sku":"SH-50ST MCD","price":5800.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d14797e278e3acbf9ea83db0d065b23.jpg?v=1788507604","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-50st-mcd-external-retaining-ring-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
