It seats in a precision groove to provide axial retention of components on shafts and spindles without the need for threads, snap grooves, or cotter pins. Made from SAE 1060-1090 steel with a cadmium finish, it delivers a hardness of 47-52 HRC and resists corrosion in demanding service environments. The three-prong E style design allows for tool-free installation and removal in many applications, making it a practical choice for production assembly and field service alike.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is used in mechanical assemblies across industrial, HVAC, and fluid-handling equipment where positive axial component retention on a shaft is required. Typical applications include motor shaft assemblies, pump components, gearboxes, and similar rotating or reciprocating machinery. It is installed by qualified mechanics and assemblers working on equipment that uses inch-dimensioned shafting. The cadmium plating makes it suitable for environments where mild corrosion resistance is needed alongside the structural performance of high-carbon steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eE style external ring seats in groove on 0.500 inch shaft diameter for positive axial retention\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 steel construction with 47-52 HRC hardness rating\u003c\/li\u003e\n  \u003cli\u003eCadmium finish provides corrosion resistance for demanding service conditions\u003c\/li\u003e\n  \u003cli\u003eThree-prong design supports fast installation and removal without special tooling in many assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets Military Specification MS 16633-1050 and ISO 13485:2015 standards\u003c\/li\u003e\n  \u003cli\u003eGroove width of 0.046 inches and groove depth of 0.052 inches for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 0.500 inch diameter shafts with a groove diameter of 0.396 inches.

Ensure the shaft groove is clean and free of burrs before seating the ring. De-energize and lock out all rotating or powered equipment before installing or removing retaining rings. Verify groove dimensions against the ring specifications prior to installation to prevent improper seating or ring failure under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: External E Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.396 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.003 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: 0.052 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.392 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.800 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 Steel (UNS G10600-G10900)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 47-52 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Cadmium-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Prongs\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: MS 16633-1050\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\u003eWeight\u003c\/strong\u003e: 0.0025 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: E-50ST MCD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51709157474610,"sku":"E-50ST MCD","price":11912.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51d381682b7fcd8c8704e747bfcbc615_fdb8240b-5526-4f1d-9231-220331af26ba.jpg?v=1788452111","url":"https:\/\/voomisupply.com\/products\/rotor-clip-e-50st-mcd-e-style-retaining-ring-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
