This hub serves as one of two required hub components in a complete coupling unit, transferring torque between shafts while accommodating minor misalignment and reducing shock loads on connected equipment. Machined to a 2.38-inch outside diameter and carrying a size 1050 coupling designation, this hub is suited for industrial drive applications where durable, repeatable coupling performance is required. Installation is performed by qualified mechanical technicians working on rotating equipment assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hub is used in industrial power transmission systems where grid-type flexible couplings are specified. A complete coupling assembly requires two hubs, one grid element, and one cover — all ordered separately. Typical applications include pump drives, compressor drives, and conveyor systems in commercial and industrial facilities. The alloy steel construction makes this hub appropriate for moderate-to-heavy duty torque transmission environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction for strength and wear resistance in demanding drive applications\u003c\/li\u003e\n  \u003cli\u003e2.38-inch outside diameter matches size 1050 coupling specifications\u003c\/li\u003e\n  \u003cli\u003eGrid-style coupling hub design accommodates angular and parallel shaft misalignment\u003c\/li\u003e\n  \u003cli\u003eSold individually — complete coupling requires two hubs, one grid, and one cover\u003c\/li\u003e\n  \u003cli\u003eSize 1050 designation allows 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 hub for size 1050 grid-type flexible coupling assemblies requiring a 2.38-inch outside diameter alloy steel hub.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanical technician with the driven and driving equipment fully de-energized and locked out per applicable LOTO procedures. Verify shaft diameter and keyway dimensions against the hub bore before pressing or fitting. A complete coupling assembly requires two hubs, one grid element, and one cover — confirm all components are on hand before beginning installation. Consult the coupling manufacturer assembly instructions for proper grid lubrication and cover torque guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 1050\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Coupling Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.23 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: 69790405234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540502348082,"sku":"69790405234","price":148.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b41dfd4707bbbd15c3d1ea28514c899.jpg?v=1785856732","url":"https:\/\/voomisupply.com\/products\/lovejoy-69790405234-flexible-coupling-hub-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
