With a 19mm maximum bore and a 6mm x 2.8mm keyway width and depth, this hub accommodates a range of shaft sizes and keyed configurations. The outer diameter measures 1.75 inches and the overall assembled length is 2.12 inches. Constructed from sintered iron, the hub delivers solid, consistent performance in industrial and HVAC mechanical drive setups. A complete flexible coupling requires two hubs and one spider element — this listing covers a single hub only. Licensed mechanics and industrial technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is suited for light-to-medium duty power transmission applications such as pump drives, fan assemblies, blower shafts, and compressor couplings. The sintered iron construction makes it appropriate for dry or lightly lubricated environments. It is commonly found in commercial HVAC mechanical rooms, industrial equipment rooms, and pump station installations where shaft-to-shaft alignment and vibration dampening are required. The L075 coupling size code identifies the appropriate spider element to pair with these hubs for a complete assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19mm maximum bore accommodates a range of shaft diameters\u003c\/li\u003e\n  \u003cli\u003e6mm x 2.8mm keyway width and depth for keyed shaft connections\u003c\/li\u003e\n  \u003cli\u003e1.75 inch outer diameter and 2.12 inch overall length for compact installations\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction provides durability in mechanical drive environments\u003c\/li\u003e\n  \u003cli\u003eCoupling size code L075 — order two hubs and one spider for a complete coupling assembly\u003c\/li\u003e\n  \u003cli\u003eRated up to 10000 RPM maximum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub corresponds to coupling size code L075. A complete flexible coupling assembly requires two hubs (68514441323) and one compatible L075 spider element. Designed as an OEM-style replacement or new-installation hub for L075-class flexible coupling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright, industrial mechanic, or HVAC technician. Shut down and lock out all connected machinery before removing or installing coupling components. Ensure the shaft bore and keyway are clean and free of burrs before pressing the hub into position. Verify shaft alignment after assembly to prevent premature spider wear and vibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore\u003c\/strong\u003e: 19mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 6mm x 2.8mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L075\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sintered Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: LOVEJOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68514441323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51539310739762,"sku":"68514441323","price":22.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8c77ee34d1cad3175233945978e2021.jpg?v=1785838175","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441323-flexible-coupling-hub-19mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
