This hub accepts a maximum bore diameter of 2 inches and a keyway measuring 1\/2 inch wide by 1\/4 inch deep, allowing secure shaft engagement. Constructed from cast iron, it delivers the durability and rigidity expected in industrial and mechanical drive systems. With an overall length of 5.69 inches and an outer diameter of 7-1\/2 inches, this hub is sized for medium-to-large coupling assemblies. Licensed mechanical contractors and millwrights typically specify this component in motor-to-pump, HVAC drive, and general industrial drivetrain setups.\u003c\/p\u003e\n\u003cp\u003eThis flexible coupling hub is suited for rotating equipment found in commercial HVAC systems, pump drives, compressor assemblies, and general industrial machinery. The cast iron construction performs reliably across a broad range of industrial environments where moderate shock loads and continuous duty cycles are present. It is rated for operation up to 3600 RPM, covering the speed range of most standard electric motors used in trade and industrial applications. When paired with an appropriate spider insert and mating hub, it forms a complete flexible jaw coupling assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 2 inches accommodates a wide range of shaft sizes\u003c\/li\u003e\n  \u003cli\u003eKeyway dimensions of 1\/2 inch wide by 1\/4 inch deep for positive shaft drive engagement\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in industrial drive applications\u003c\/li\u003e\n  \u003cli\u003e7-1\/2 inch outer diameter and 5.69 inch overall length suit medium-to-large coupling assemblies\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM, compatible with standard single- and three-phase motor speeds\u003c\/li\u003e\n  \u003cli\u003eCoupling Size Code 10S for matching with appropriate mating components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible coupling hub for use in jaw-type flexible coupling assemblies requiring a Size Code 10S hub with a 2 inch maximum bore.

De-energize and lock out all power to the connected motor and driven equipment before handling the coupling assembly. Ensure shaft and bore surfaces are clean and free of burrs before pressing or sliding the hub into position. Consult applicable machinery safety standards and the equipment manufacturer's documentation for alignment tolerances and shaft fit specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 7-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 10S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.17 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: 68514436180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542300688690,"sku":"68514436180","price":199.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9cbb4a06a7c7cb241cba57ec44196d0_18a59fe5-41dd-4301-8bc1-73a74abc6d85.jpg?v=1785897381","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514436180-flexible-coupling-hub-2-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
