This hub features an 11mm maximum bore with a 4mm wide by 1.8mm deep keyway, a 1.36-inch outer diameter, and an overall length of 2 inches. Constructed from sintered iron, it offers reliable strength and wear resistance for industrial and mechanical drive applications. A complete flexible coupling assembly requires two hubs and one spider insert, each ordered separately.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is suited for light-to-medium duty power transmission setups in industrial machinery, pumps, compressors, and mechanical drive systems. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on equipment requiring flexible shaft-to-shaft connections. The compact dimensions make it appropriate for space-constrained drive train configurations. Always order two hubs and one spider to complete the assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11mm maximum bore accommodates standard metric shafts\u003c\/li\u003e\n  \u003cli\u003e4mm x 1.8mm keyway for positive rotational drive engagement\u003c\/li\u003e\n  \u003cli\u003e1.36-inch outer diameter and 2-inch overall length for compact fitment\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRated up to 14,000 RPM for high-speed drive applications\u003c\/li\u003e\n  \u003cli\u003eCoupling Size Code L070 for cross-reference and spider selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in flexible jaw-type coupling assemblies with Coupling Size Code L070.

Disconnect and lock out all power sources before handling shaft components. Ensure shaft and bore dimensions are verified prior to pressing or sliding the hub onto the shaft. Do not exceed the rated maximum RPM, and confirm spider element material is appropriate for the operating load and environment before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore\u003c\/strong\u003e: 11mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 4mm x 1.8mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 14,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sintered Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L070\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: 68514441453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51543624646962,"sku":"68514441453","price":17.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdd457ccdb0172b6c11a523c2b0fc9f1.jpg?v=1785921027","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441453-flexible-coupling-hub-11mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
