Stamped from SAE 1060-1090 steel and heat-treated to a hardness of 37-43 HRC, this ring delivers reliable axial retention in moderate to demanding applications. The phosphate finish provides baseline corrosion resistance and improves lubricant retention. With a groove diameter of 0.303 inches and a ring thickness of 0.035 inches, the ring is engineered for precise fit in standard E-ring grooves. This part is installed by mechanical assemblers, maintenance technicians, and field service professionals working with shafted components across industrial and commercial equipment.\u003c\/p\u003e\u003cp\u003eThis retaining ring is suited for use on 3\/8-inch diameter shafts where an external E-style ring is the specified fastener. The three-prong E-ring design allows for tool-free or needle-nose installation and removal, making it practical in tight assemblies. Typical applications include small motors, pump shafts, gearboxes, conveyor components, and any mechanism requiring a low-profile external retaining feature. The phosphate finish is appropriate for light-duty corrosive environments or applications where a secondary lubricant or coating will be applied.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE-style external ring fits 3\/8-inch shaft diameter with 0.303-inch groove diameter\u003c\/li\u003e\n\u003cli\u003eSAE 1060-1090 steel construction with hardness of 37-43 HRC for reliable retention strength\u003c\/li\u003e\n\u003cli\u003ePhosphate finish improves corrosion resistance and lubricant adhesion\u003c\/li\u003e\n\u003cli\u003eThree-prong design enables straightforward installation and removal with standard tools\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.035 inches with tight tolerance for consistent groove fit\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\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external E-style retaining ring for 3\/8-inch shafts with a groove diameter of 0.303 inches, conforming to SAE 1060-1090 and UNS G10600-G10900 fastener standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove E-style retaining rings using appropriate external ring pliers or needle-nose pliers to avoid deforming the prongs or ring body. Ensure the shaft groove is clean and free of burrs before seating the ring. Always de-energize and lock out equipment before servicing any shafted component. Do not reuse a ring that has been removed, as repeated installation cycles can 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 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\u003eMaterial\u003c\/strong\u003e: SAE 1060-1090 Steel (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: Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Prongs\u003c\/strong\u003e: 3\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: 0.00148 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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 PA B100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51691354194226,"sku":"E-37ST PA B100","price":956.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84fe942497c45d4eb21d59fc4388db26.jpg?v=1788283659","url":"https:\/\/voomisupply.com\/products\/rotor-clip-e-37st-pa-b100-external-e-style-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
