It carries a coupling size rating of 5 and accepts a 7\/8-inch bore with a round keyed configuration. Bore tolerances are held to +0.0005 inches \/ +0.0015 inches for a precise shaft fit. The hub is machined from carbon steel and has an outside diameter of 3-1\/4 inches. Maximum rated speed is 7,600 RPM. The flange mates with a matched sleeve insert to complete the coupling assembly, accommodating both angular and parallel misalignment along with end float and vibration through a 4-way flexing action.\u003c\/p\u003e\u003cp\u003eThis coupling flange suits power transmission applications across a range of industrial and commercial equipment. Typical use cases include electric motor-to-pump connections, compressor drive trains, and conveyor shaft assemblies. The chemical-resistant and oil-resistant construction makes it appropriate for environments where incidental fluid exposure is expected. Installation is common in both new equipment builds and field replacement of worn or damaged coupling flanges in mechanical drive systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore round keyed design for direct shaft mounting with tight gap tolerances\u003c\/li\u003e\n\u003cli\u003e4-way flexing action absorbs shock, vibration, angular misalignment, parallel misalignment, and end float\u003c\/li\u003e\n\u003cli\u003eCarbon steel hub construction with chemical and oil resistance\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 7,600 RPM\u003c\/li\u003e\n\u003cli\u003eIncludes two set screws: one positioned over keyseat and one at 90 degrees\u003c\/li\u003e\n\u003cli\u003eRated for compressors, conveyors, motors, and pumps\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation coupling flange for size 5 sleeve coupling assemblies using keyed shafts measured in inch dimensions.

De-energize and lock out the drive motor before removing or installing any coupling components per OSHA lockout\/tagout procedures. Verify shaft diameter and keyway dimensions match the bore and keyway specs of this flange before pressing or sliding onto the shaft. Torque set screws using a calibrated hex key to the fastener manufacturer specification for the 5\/16-18 thread size; do not overtighten against the keyseat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 5\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: +0.0005 inches \/ +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: 1-3\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 29\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 7,600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMisalignment Types\u003c\/strong\u003e: Angular, Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: (2) Set Screws, 5\/16-18 thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-5J78\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383480287538,"sku":"TB-5J78","price":63.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670410.jpg?v=1782597942","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-5j78-sleeve-coupling-flange-size-5-keyed","provider":"Voomi Supply","version":"1.0","type":"link"}
