Built from cast iron, this hub features a maximum bore diameter of 1-1\/4 inches and a keyway sized at 1\/4 inch wide by 1\/8 inch deep. The outer diameter measures 4 inches with an overall length of 3-1\/2 inches. It carries a maximum speed rating of 6000 RPM, making it suitable for a range of industrial drive and mechanical power transmission setups. Installation is typically handled by mechanical contractors, millwrights, or HVAC technicians working on motor-driven equipment.\u003c\/p\u003e\n\u003cp\u003eThis flexible coupling hub fits into applications where rotational power must be transferred between shafts while accommodating minor angular, parallel, or axial misalignment. The cast iron construction supports use in commercial and light industrial equipment such as pumps, compressors, fans, and blowers. The coupling size code is 6J, which corresponds to a specific spider or insert element within the Lovejoy jaw coupling product family. It is suitable for use in both new installations and replacement scenarios on existing mechanical drive systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 1-1\/4 inches for shaft fitment flexibility\u003c\/li\u003e\n  \u003cli\u003eKeyway dimensions of 1\/4 inch wide by 1\/8 inch deep for positive torque transfer\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e4 inch outer diameter and 3-1\/2 inch overall length for compact installation\u003c\/li\u003e\n  \u003cli\u003eRated to 6000 RPM for medium- to high-speed drive applications\u003c\/li\u003e\n  \u003cli\u003eCoupling size code 6J for compatibility with matching jaw coupling components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible jaw coupling hub for use with size 6J spider inserts and mating hubs in standard jaw-type flexible coupling assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, mechanical contractor, or licensed HVAC technician. De-energize and lock out all power to the driven equipment before beginning work, following OSHA lockout\/tagout procedures. Ensure the bore and keyway are clean and free of burrs before pressing or sliding the hub onto the shaft. Verify shaft and hub alignment within the coupling manufacturer's specified tolerances before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width x Depth\u003c\/strong\u003e: 1\/4 inches x 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 6000 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: 6J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.88 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: 68514436086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540542882098,"sku":"68514436086","price":51.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9cbb4a06a7c7cb241cba57ec44196d0_4f42f57d-59a5-4d69-a77a-4cb43c7da47b.jpg?v=1785858025","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514436086-flexible-coupling-hub-1-1-4-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
