With a maximum bore diameter of 1-1\/4 inches and an outer diameter of 4-1\/2 inches, this hub fits into the L190 coupling size family and handles shaft speeds up to 5,000 RPM. The sintered iron construction provides reliable strength and wear resistance in demanding industrial and trade environments. This type of coupling is typically installed by millwrights, HVAC technicians working on mechanical drive assemblies, or industrial maintenance professionals who require precise shaft alignment management.\u003c\/p\u003e\n\u003cp\u003eFlexible hub couplings in this size range are commonly used in light to medium-duty drive systems including fan and blower assemblies, pump drives, and compressor shaft connections. The L190 size designation makes this hub compatible with the corresponding spider insert and mating hub components used in standard jaw-type flexible coupling configurations. An overall assembled length of 4.88 inches suits typical inline shaft arrangements where angular and parallel misalignment must be absorbed without transmitting shock loads downstream.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 1-1\/4 inches accommodates common shaft sizes in fan and pump drives\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction offers consistent density and resistance to wear under rotational load\u003c\/li\u003e\n  \u003cli\u003eRated to 5,000 RPM for compatibility with higher-speed motor and blower applications\u003c\/li\u003e\n  \u003cli\u003eL190 coupling size code enables straightforward identification of matching spider inserts and mating hubs\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch outer diameter and 4.88 inch overall length suit standard inline drive configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub is designated as coupling size code L190 and is designed to pair with corresponding L190-series spider inserts and mating hub components in jaw-type flexible coupling assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize all drive equipment and lock out the power source before removing or installing any coupling component. Inspect shaft keyways and set screw threads before mounting the hub to ensure proper engagement and concentricity. A qualified millwright or mechanical technician should verify shaft alignment within manufacturer tolerances before operating the assembled drive. Consult applicable ANSI and OSHA mechanical power transmission standards for guarding and safety requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L190\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 5,000 RPM\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: 6.93 pounds\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: 68514412292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51541832007986,"sku":"68514412292","price":171.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/674b0dcb7ce256c262c5be658eaaef2e.jpg?v=1785886211","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514412292-flexible-hub-coupling-1-1-4-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
