Built from cast iron, this hub features a maximum bore diameter of 5\/8 inches and a keyway measuring 3\/16 inches wide by 3\/32 inches deep. The outside diameter is 3-1\/4 inches with an overall length of 2.88 inches. It is rated to a maximum of 7,600 RPM, making it suitable for moderate- to high-speed drive applications. Licensed mechanics and millwrights typically install these components in pump, blower, compressor, and HVAC equipment drive trains.\u003c\/p\u003e\u003cp\u003eThis flexible coupling hub fits into a wide range of industrial and commercial mechanical drive systems. It is well-suited for use in pump drives, fan assemblies, and compressor couplings where a keyed shaft connection is required. The cast iron construction handles the demands of continuous-duty rotating equipment. This hub corresponds to Lovejoy coupling size code 5J and is sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum bore diameter of 5\/8 inches for compatibility with small-to-mid shaft sizes\u003c\/li\u003e\n\u003cli\u003eKeyway dimensions of 3\/16 inches wide by 3\/32 inches deep for positive keyed shaft engagement\u003c\/li\u003e\n\u003cli\u003eCast iron construction provides durability in continuous-duty mechanical drive applications\u003c\/li\u003e\n\u003cli\u003e3-1\/4 inch outside diameter and 2.88 inch overall length for compact installation\u003c\/li\u003e\n\u003cli\u003eRated to 7,600 RPM maximum for moderate- to high-speed drive systems\u003c\/li\u003e\n\u003cli\u003eCoupling size code 5J for cross-reference and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit flexible coupling hub for mechanical drive assemblies requiring a 5\/8 inch bore keyed hub with Lovejoy size code 5J specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright. Disconnect and lock out all power to the drive system before removing or installing any coupling component. Ensure the mating shaft, keyway, and spider element are inspected and in good condition before assembly. Consult applicable ANSI or equipment manufacturer alignment specifications to verify shaft alignment before returning the drive to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 3\/16 inches x 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter (OD)\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 7,600 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: 5J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 68514436058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540647444786,"sku":"68514436058","price":48.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9cbb4a06a7c7cb241cba57ec44196d0_2eeb889e-050e-47e9-baf9-95c8651760df.jpg?v=1785860823","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514436058-flexible-coupling-hub-5-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
