Sized at coupling size 6 with a 4-inch outside diameter and a 7\/8-inch round keyed bore, this flange mounts directly to a keyed shaft with tight bore tolerances of plus 0.0005 to plus 0.0015 inches. It pairs with a matched sleeve insert to complete the coupling assembly. The cast iron hub body delivers durability in demanding mechanical environments. Rated to 6,000 RPM maximum speed, it accommodates both angular and parallel misalignment while absorbing shock, vibration, and end float through a 4-way flexing action. Licensed mechanical tradespeople and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe TB-6J78 coupling flange suits a broad range of rotating equipment in both light industrial and commercial settings. Typical applications include compressors, conveyors, motors, and pumps where a reliable close-coupled shaft connection is required. The flange is chemical resistant and oil resistant, making it appropriate for wet or chemically active environments such as pump rooms and process equipment areas. Two set screws are included, positioned one over the keyseat and one at 90 degrees, securing the flange to the shaft without additional hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore design with 7\/8-inch round keyed bore for direct shaft mounting\u003c\/li\u003e\n  \u003cli\u003e4-way flexing action absorbs shock, vibration, misalignment, and end float\u003c\/li\u003e\n  \u003cli\u003eAccommodates both angular and parallel shaft misalignment\u003c\/li\u003e\n  \u003cli\u003eCast iron hub construction with chemical and oil resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 6,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eIncludes two set screws pre-positioned for secure keyed shaft retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a coupling size 6 OEM-style sleeve coupling flange for use with compatible matched sleeve inserts on keyed shafts in compressor, conveyor, motor, and pump drive train assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright or industrial maintenance mechanic. De-energize and lock out all connected equipment before mounting or removing coupling components in accordance with applicable OSHA lockout\/tagout procedures. Verify shaft and bore dimensions and keyway fit before final assembly. Do not exceed the rated maximum speed of 6,000 RPM in the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 6,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Tolerance\u003c\/strong\u003e: plus 0.0005 inches \/ plus 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Flange Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMisalignment Type\u003c\/strong\u003e: Angular and Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: 2 Set Screws (5\/16 inches-18 thread, one over keyseat and one at 90 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Properties\u003c\/strong\u003e: Chemical Resistant, Oil Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA (subject to change)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC\u003c\/strong\u003e: 31163003\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: TB WOODS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TB-6J78\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383517741362,"sku":"TB-6J78","price":80.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670427.jpg?v=1782599161","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-6j78-sleeve-coupling-flange-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
