It mounts directly to a compatible keyed shaft using tight gap tolerances, maintaining precise shaft alignment and torque transfer. At a coupling size of 6 and an outside diameter of 4 inches, this cast iron flange pairs with a matched sleeve insert to complete the coupling assembly. Rated to 6,000 RPM maximum speed, it is suited for moderate- to high-speed rotating equipment. Millwrights, mechanical contractors, and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis flange is used in industrial and commercial mechanical systems where shaft-to-shaft coupling is required, including pumps, compressors, fans, and general power transmission setups. The close-coupled design keeps the assembly compact, reducing bearing load and minimizing shaft deflection. It is appropriate for both new installations and replacement work on existing equipment using the TB-6J series sleeve coupling system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore design for direct mounting to keyed shafts\u003c\/li\u003e\n\u003cli\u003e6 coupling size with 4 inch outside diameter\u003c\/li\u003e\n\u003cli\u003e6,000 RPM maximum rated speed\u003c\/li\u003e\n\u003cli\u003eCast iron construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eMates with a matched sleeve insert for a complete coupling assembly\u003c\/li\u003e\n\u003cli\u003eTight gap tolerances support precise shaft alignment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for TB-6J series sleeve coupling assemblies requiring a size 6 finished bore flange.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the driven equipment before beginning shaft work. Ensure the mating shaft is clean, properly keyed, and within the bore tolerance of the flange before pressing or sliding the flange into position. Always use the matched sleeve insert specified for this coupling size to complete the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Finished Bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TBWOODSTB6J138\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TB-6J138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51525447221554,"sku":"TB-6J138","price":85.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e47c891173961560103ac9446ea74650.jpg?v=1785473972","url":"https:\/\/voomisupply.com\/products\/tbwoodstb6j138-tb-6j138-sleeve-coupling-flange-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
