With a maximum bore diameter of 1-1\/8 inches and an outer diameter of 4-1\/2 inches, this coupling accommodates moderate-to-large shaft assemblies where misalignment damping and vibration absorption are required. The sintered iron construction provides solid load-bearing capacity in demanding service environments. At an overall length of 4.88 inches and a rated maximum speed of 5,000 RPM, this hub is suited for industrial motors, pumps, compressors, and HVAC equipment drives where reliable torque transfer is critical. Installers and maintenance technicians working on mechanical drive trains will find this a direct-fit hub component.\u003c\/p\u003e\n\u003cp\u003eThis flexible hub coupling is used in industrial and commercial mechanical drive applications where rotational power must be transferred between two shafts with some tolerance for angular, parallel, or axial misalignment. Typical installations include motor-to-pump couplings, blower drive assemblies, and compressor connections in both HVAC mechanical rooms and general industrial settings. The hub pairs with a matching spider insert and mating hub to form a complete jaw-style flexible coupling assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 1-1\/8 inches accommodates a range of shaft sizes\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch outer diameter suits medium-to-large drive assemblies\u003c\/li\u003e\n  \u003cli\u003e4.88 inch overall length provides adequate engagement depth for secure shaft coupling\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction offers durability under continuous rotational load\u003c\/li\u003e\n  \u003cli\u003eRated to 5,000 RPM for use with standard industrial and HVAC drive motors\u003c\/li\u003e\n  \u003cli\u003eSize code L190 for straightforward cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket flexible hub coupling for mechanical drive assemblies requiring a maximum bore of 1-1\/8 inches and size code L190 jaw-style coupling hubs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with mechanical power transmission components. Disconnect and lock out all power to the drive system before removing or installing coupling components. Ensure the bore, keyway, and set screw are properly aligned and secured before returning the drive to service. Consult applicable equipment service documentation and relevant ANSI or OSHA standards for shaft coupling installation requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-1\/8 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\u003eCoupling Size Code\u003c\/strong\u003e: L190\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: 68514412290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542194684210,"sku":"68514412290","price":171.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/068f48aabb5be86c816149bd751a99e2.jpg?v=1785894777","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514412290-flexible-hub-coupling-1-1-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
