With a 2.375-inch inside bore and a 5.5-inch outside diameter, this hub is built for high-torque applications where zero backlash and solid mechanical alignment are required. Machined from carbon steel, it provides the strength and durability demanded in industrial and commercial drive train assemblies. A 0.625-inch wide by 0.3125-inch deep keyway is cut into the bore, securing the hub to a keyed shaft and preventing rotational slip under load. Licensed millwrights, maintenance mechanics, and industrial technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis rigid coupling hub is suited for fixed-speed shaft coupling applications in industrial machinery, pumping systems, compressor drives, and commercial HVAC equipment where shaft misalignment is not present or has been corrected prior to assembly. The keyway configuration is compatible with standard inch-series keyed shafts. It is sold as a single hub unit, intended to be paired with a corresponding mating hub and coupling element appropriate to the drive system design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.375-inch inside bore accommodates standard inch-series keyed shafts\u003c\/li\u003e\n  \u003cli\u003e5.5-inch outside diameter for robust torque transmission capacity\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eIntegral keyway — 0.625 inches wide by 0.3125 inches deep — prevents rotational slip on keyed shafts\u003c\/li\u003e\n  \u003cli\u003eRigid design eliminates backlash and maintains precise shaft alignment\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging allows replacement or custom coupling assembly builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation rigid coupling hub for standard inch-series keyed shaft applications in industrial and commercial mechanical drive systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright or qualified maintenance mechanic. Always de-energize and lock out the drive system before removing or installing any coupling component, following OSHA lockout\/tagout procedures. The shaft and bore should be cleaned and inspected for burrs before assembly; a proper hub installation tool or hydraulic press is recommended to avoid damage to the bore or shaft. Verify shaft alignment to manufacturer tolerances before final assembly, as rigid couplings do not compensate for angular or parallel misalignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Bore Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Configuration\u003c\/strong\u003e: With Keyway\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: 69790400099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51539431194930,"sku":"69790400099","price":614.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f14646309ac3316979b61f7a36e1d3af_9ffdbcd9-8f0c-4d7f-bcb3-56d134b83c6b.jpg?v=1785840126","url":"https:\/\/voomisupply.com\/products\/lovejoy-69790400099-rigid-coupling-hub-2-375in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
