With a maximum bore diameter of 1-1\/8 inches, an outer diameter of 3-3\/4 inches, and an overall length of 4-1\/2 inches, this hub is sized for mid-range drive applications. Constructed from sintered iron, it offers consistent dimensional accuracy and adequate wear resistance for industrial and mechanical service environments. The coupling is rated to a maximum of 5000 RPM, making it suitable for moderate- to high-speed shaft connections. HVAC equipment technicians, mechanical contractors, and industrial maintenance personnel are the typical installers of this type of hub coupling.\u003c\/p\u003e\n\u003cp\u003eThis flexible hub coupling is used in mechanical power transmission applications where shaft-to-shaft torque transfer is required with some capacity for angular, parallel, or axial misalignment. Typical installations include HVAC fan assemblies, pump drives, compressor drive trains, and general industrial machinery. The L150 coupling size code identifies this hub within the standard jaw-style flexible coupling series, allowing pairing with the appropriate spider insert for the application load requirements.\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 up to that dimension\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 inch outer diameter and 4-1\/2 inch overall length suit mid-range drive assemblies\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction provides dimensional consistency and durability in drive service\u003c\/li\u003e\n  \u003cli\u003eRated to 5000 RPM maximum for moderate- to high-speed applications\u003c\/li\u003e\n  \u003cli\u003eCoupling size code L150 for standard spider insert compatibility\u003c\/li\u003e\n  \u003cli\u003eSold as a single hub unit; spider element selected separately based on load class\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub coupling carries the L150 coupling size code and is designed for use within the standard jaw-type flexible coupling system, requiring a matching L150-series spider insert. Verify bore diameter and keyway requirements against the driven shaft before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanical contractor or maintenance technician. Disconnect and lock out all power to the drive system before mounting or removing any coupling component in accordance with OSHA lockout\/tagout procedures. Ensure shaft surfaces are clean and free of burrs before pressing or sliding the hub into position, and confirm hub set screws or keyways are properly engaged before returning the drive to service. Do not exceed the rated 5000 RPM maximum speed for this coupling.\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 (OD)\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 5000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L150\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: 4.15 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: 68514412109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51544061051186,"sku":"68514412109","price":122.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f31b76e90cb4d970d256351255ff0bb1.jpg?v=1785923454","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514412109-flexible-hub-coupling-1-1-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
