This hub features a 19mm maximum bore and a 6mm wide by 2.8mm deep keyway for secure shaft engagement. The hub measures 1.36 inches in outer diameter and 2 inches in overall length, making it a compact component suited for tight drive train configurations. Constructed from sintered iron, it offers consistent dimensional accuracy and adequate strength for moderate-duty rotating equipment applications. Two hubs and one spider element are required to complete a full flexible coupling assembly.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is used in mechanical drive systems where a flexible element is needed between two shafts to accommodate slight angular, parallel, or axial misalignment. Typical applications include pump drives, compressor drives, conveyor systems, and light industrial machinery. The L070 coupling size code designates the hub family and determines compatibility with the appropriate spider insert. Licensed mechanical contractors and industrial maintenance technicians are the typical installers for this type of component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19mm maximum bore accommodates a range of shaft sizes up to that diameter\u003c\/li\u003e\n  \u003cli\u003e6mm x 2.8mm keyway width and depth for positive keyed shaft connection\u003c\/li\u003e\n  \u003cli\u003e1.36 inch outer diameter and 2 inch overall length for compact installation footprint\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction provides consistent dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eRated to 14000 RPM maximum for high-speed drive applications\u003c\/li\u003e\n  \u003cli\u003eCoupling size code L070 for spider and mating hub selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub is part of the L070 coupling size family. Two hubs of this part number paired with one appropriately rated spider element are required to complete a functional flexible coupling assembly. Consult the LOVEJOY L070 series selection guide to confirm spider durometer and torque rating for the specific application.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of flexible coupling hubs is typically performed by licensed mechanical or industrial maintenance technicians. Disconnect and lock out all power to the drive system before mounting or removing any coupling components. Ensure shaft and bore surfaces are clean and free of burrs before pressing or sliding the hub onto the shaft. Do not operate the coupling above the rated maximum RPM, and verify proper spider installation between the two hubs before returning the drive system to service.\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: 1.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sintered Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 14000 RPM\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: 68514441319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540448346418,"sku":"68514441319","price":20.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f3ffa4690ef460cdc388224ebbb6ad2.jpg?v=1785855474","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441319-flexible-coupling-hub-19mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
