With a coupling size of 3 and an outside diameter of 2-1\/16 inches, this carbon steel flange mounts directly to a keyed round bore shaft with a bore diameter of 1\/2 inch and a bore tolerance of +0.0005 inches to +0.0015 inches. It pairs with a matched sleeve insert to complete the coupling assembly. Rated to a maximum speed of 9,200 RPM, this flange is built for demanding rotating equipment applications installed by mechanical and industrial service technicians.\u003c\/p\u003e\n\u003cp\u003eThis sleeve coupling flange is suited for use in both light industrial and commercial applications involving compressors, conveyors, motors, and pumps. It handles angular and parallel misalignment through a 4-way flexing action that also absorbs shock, vibration, and end float. The flange is compatible with inch-measurement keyed shafts and is a common choice in pump and motor close-coupling configurations where tight shaft engagement and chemical and oil resistance are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbon steel hub construction with chemical and oil resistance for harsh service environments\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\u003eFinished bore with 1\/16-inch keyway width and 1\/8-inch keyway depth for secure keyed shaft engagement\u003c\/li\u003e\n  \u003cli\u003eIncludes two set screws — one over keyseat and one at 90 degrees — threaded 1\/4-20\u003c\/li\u003e\n  \u003cli\u003eRated to 9,200 RPM maximum speed for high-cycle rotating equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with inch-measurement round keyed shafts on compressors, conveyors, motors, and pumps requiring a size 3 sleeve coupling assembly with a matched sleeve insert.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a millwright or mechanical technician. Disconnect and lock out all power to the drive system before mounting or removing coupling flanges. Verify shaft and bore dimensions and keyway alignment before pressing or sliding the flange onto the shaft. Follow applicable ANSI and OSHA machinery guarding standards when coupling assemblies are installed in rotating equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 9,200 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1\/2 inch\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\u003eOutside Diameter\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round Keyed\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, 1\/4-20 thread\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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\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-3J12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383777788210,"sku":"TB-3J12","price":37.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670381.jpg?v=1782607165","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-3j12-sleeve-coupling-flange-3-coupling-size","provider":"Voomi Supply","version":"1.0","type":"link"}
