This hub features a 38mm maximum bore with a 10mm wide by 3.3mm deep keyway for secure shaft engagement. The hub measures 3.31 inches in outer diameter and 4.25 inches in overall length, and is constructed from sintered iron for durability under rotational load. Rated to 5,000 RPM, this hub is a component part — two hubs and one spider element are required to form a complete flexible coupling assembly.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is suited for industrial and commercial mechanical drive systems, including pump drives, compressor shafts, conveyor systems, and general power transmission equipment. It is installed by mechanical contractors, millwrights, and industrial maintenance technicians wherever a jaw-style flexible coupling is needed to connect two shaft ends while accommodating minor misalignment and absorbing torsional shock loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e38mm maximum bore with 10mm x 3.3mm keyway for positive shaft engagement\u003c\/li\u003e\n  \u003cli\u003e3.31 inches outer diameter and 4.25 inches overall length\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 5,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCoupling Size Code L110 for standard jaw coupling spider compatibility\u003c\/li\u003e\n  \u003cli\u003eSold individually — two hubs plus one spider required for a complete coupling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a component of the LOVEJOY L-series jaw flexible coupling system, Size Code L110.

De-energize and lock out the drive equipment before mounting the hub onto the shaft. Ensure the shaft is clean and within the specified bore tolerance before pressing or sliding the hub into position and securing via the keyway. Consult the equipment manufacturer specifications and applicable ANSI or OSHA lockout\/tagout procedures before beginning work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore\u003c\/strong\u003e: 38mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 10mm x 3.3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L110\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: 2.66 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: 68514441335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540630339890,"sku":"68514441335","price":101.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/168f7e2aca50d1e2ea0e3fdfb9f94d38.jpg?v=1785860529","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441335-flexible-coupling-hub-38mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
