Designed for a 3\/8-inch (0.375-inch) shaft diameter, the ring seats into a groove with a 0.303-inch groove diameter and holds position with three prongs for reliable axial retention. Manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating, it delivers corrosion resistance and a hardness rating of 37-43 HRC. Maintenance technicians, millwrights, and assembly professionals working with shaft-mounted components rely on this ring for fast, tool-assisted installation and removal.\u003c\/p\u003e\u003cp\u003eThis retaining ring is suited for use in rotating shaft assemblies across a range of industrial, HVAC, and mechanical applications where a compact external E-style ring is required. Its inch-measurement design fits standard 3\/8-inch shafts common in motors, pumps, and light-duty drive assemblies. The zinc-dichromate finish provides additional protection in environments with moderate exposure to moisture or mild chemicals. This part is sold individually but is subject to a minimum order quantity of 100 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE-style three-prong design for tool-assisted installation and secure axial retention on 3\/8-inch shafts\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish for corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n\u003cli\u003eSAE 1060-1090 carbon steel construction with 37-43 HRC hardness for consistent spring performance\u003c\/li\u003e\n\u003cli\u003eGroove diameter of 0.303 inches with a groove width of 0.039 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.035 inches and free outside diameter of 0.66 inches\u003c\/li\u003e\n\u003cli\u003eMeets SAE 1060-1090 and UNS G10600-G10900 standards; manufactured under ISO 13485:2015 quality system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external E-style retaining ring for standard 3\/8-inch shaft diameters in inch-measurement mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed using proper external E-ring pliers or snap ring tools to prevent ring distortion or personal injury. Always de-energize and lock out the equipment before servicing any shaft-mounted assembly. Confirm groove dimensions match the ring specifications before installation. Do not over-spread the ring during installation, as exceeding the elastic limit will reduce retention force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.303 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\u003eFree Diameter\u003c\/strong\u003e: 0.300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.660 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: 0.036 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\u003eNumber of Prongs\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: SAE 1060-1090 (UNS G10600-G10900)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 37-43 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\u003eWeight\u003c\/strong\u003e: 0.0015 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-37ST ZD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51701174731058,"sku":"E-37ST ZD","price":1476.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2f9a252b0b5e270dc857baa3a5a5de6.jpg?v=1788399305","url":"https:\/\/voomisupply.com\/products\/rotor-clip-e-37st-zd-external-e-retaining-ring-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
