It accepts a maximum bore of 25mm and includes an 8mm wide by 3.3mm deep keyway for positive shaft engagement. The hub measures 2.11 inches in outer diameter and 2.12 inches in overall length, and is constructed from sintered iron for durability under rotational load. Rated to 9,000 RPM, this hub suits high-cycle industrial and commercial drive applications. Two hubs and one spider element are required to form a complete flexible coupling assembly. Mechanical technicians and industrial service professionals install this component as part of motor-to-load coupling systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is used in applications where shaft misalignment absorption and vibration dampening are needed between a driver and driven component. Typical installations include pump drives, compressor drives, conveyor systems, and other rotating equipment found in commercial HVAC, industrial, and mechanical service environments. The sintered iron construction handles the torsional demands of continuous-duty operation. Because two hubs and one spider are required for a complete coupling, confirm the mating hub size code matches before ordering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25mm maximum bore accommodates a range of shaft diameters\u003c\/li\u003e\n  \u003cli\u003e8mm x 3.3mm keyway provides positive rotational engagement\u003c\/li\u003e\n  \u003cli\u003e2.11-inch OD and 2.12-inch overall length in a compact profile\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 9,000 RPM for high-speed drive applications\u003c\/li\u003e\n  \u003cli\u003eCoupling Size Code L090 for hub-to-hub and spider compatibility reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the L090 coupling size family. Two hubs of matching size code and one compatible spider element are required to complete the assembly. Verify bore, keyway dimensions, and size code against the mating hub and spider before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical or industrial service technicians. De-energize and lock out all power to the drive system before removing or installing coupling components, following applicable LOTO procedures. Ensure shaft and bore dimensions are within tolerance before pressing or sliding the hub into position. Do not operate the coupling assembly without the spider element seated between both hubs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore\u003c\/strong\u003e: 25mm\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: 2.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 9,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L090\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: 0.63 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: 68514441464\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51538795266354,"sku":"68514441464","price":29.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2db9120f1937cc1c0a484f11a1cc95b7.jpg?v=1785826828","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441464-flexible-coupling-hub-25mm-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
