It accepts a maximum bore of 24mm and features an 8mm wide by 3.3mm deep keyway for positive shaft engagement. With an outer diameter of 3.31 inches and an overall length of 4.25 inches, this hub is constructed from sintered iron for durability under rotational stress. It is rated to 5000 RPM at the L110 coupling size code. A complete coupling assembly requires two hubs and one spider insert, which are ordered separately. Licensed HVAC, mechanical, and industrial technicians install these hubs in pump, fan, compressor, and motor drive trains.\u003c\/p\u003e\n\u003cp\u003eThis flexible coupling hub is suited for residential and light commercial mechanical systems where shaft misalignment compensation and vibration dampening are required. Typical applications include close-coupled pump and motor assemblies, blower drive systems, and compressor input shafts. The sintered iron construction handles moderate torque loads and resists wear under continuous-duty cycling. The keyway configuration provides a positive drive connection without relying solely on set-screw retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24mm maximum bore accommodates common metric shaft sizes\u003c\/li\u003e\n  \u003cli\u003e8mm x 3.3mm keyway for positive shaft-to-hub torque transfer\u003c\/li\u003e\n  \u003cli\u003e3.31 inch outer diameter and 4.25 inch overall length in sintered iron construction\u003c\/li\u003e\n  \u003cli\u003eRated to 5000 RPM at L110 coupling size code\u003c\/li\u003e\n  \u003cli\u003eFlexible coupling design compensates for minor shaft misalignment and reduces vibration transmission\u003c\/li\u003e\n  \u003cli\u003eSold individually — order two hubs and one spider for a complete coupling assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hub for L110-series flexible jaw coupling assemblies.

De-energize and lock out the drive motor before any coupling work. Verify shaft and bore dimensions before pressing or fitting the hub, and ensure the keyway and key are properly seated before applying set screws. Consult applicable ANSI and OSHA lockout-tagout standards during service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore\u003c\/strong\u003e: 24mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 8mm 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: 5000 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: 2.95 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: 68514448301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540162806066,"sku":"68514448301","price":101.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56aa581fb61c2795124d41217a78e877.jpg?v=1785847591","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514448301-flexible-coupling-hub-24mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
