Part of the EC050 series with size code ES075, this hub accepts a minimum bore diameter of 0.25 inches and measures 0.75 inches in both outside diameter and overall length. It uses a set screw retention style and is rated for up to 5 in-lb of torque. Technicians in HVAC, mechanical, and industrial applications install this hub as one half of a two-piece flexible coupling system to transmit rotational motion between shafts while accommodating minor misalignment.\u003c\/p\u003e\u003cp\u003eThis hub is suited for light-duty coupling applications in residential and commercial mechanical systems where compact size and corrosion resistance are priorities. Its anodized aluminum construction keeps weight low at 0.03 pounds while providing a durable, oxide-hardened surface. The set screw style allows for straightforward shaft retention without specialized tooling. It is commonly paired with a matching flexible coupling insert and opposing hub to complete the drive assembly in small motor or pump configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAnodized aluminum construction for corrosion resistance and reduced weight\u003c\/li\u003e\n\u003cli\u003eSet screw retention style for secure, tool-accessible shaft locking\u003c\/li\u003e\n\u003cli\u003e0.75 inches OD and 0.75 inches overall length for compact installation envelopes\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.25 inches fits common small-shaft applications\u003c\/li\u003e\n\u003cli\u003eRated to 5 in-lb torque for light-duty drive applications\u003c\/li\u003e\n\u003cli\u003ePart of the EC050 series, size code ES075\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation screw hub for EC050 series flexible coupling assemblies requiring the ES075 size code with a 0.25 inches minimum bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, plumber, or mechanical contractor. De-energize and lock out all power to the drive system before handling any coupling components. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Tighten the set screw to the fastener manufacturer's specification using the appropriate hex key and verify coupling alignment before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EC050\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: ES075\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Screw Hub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Set Screw Type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Anodized Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 5 in-lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: LOVEJOY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68514456626\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51538886820146,"sku":"68514456626","price":129.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/675f96caabb1547f77b0f0b3cfa05631.jpg?v=1785828831","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514456626-flexible-screw-hub-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
