The TBWOODSTB6J138 TB-6J138 is a finished bore sleeve coupling flange designed for close-coupled shaft connections in mechanical power transmission applications. 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.
This 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.
Designed as an OEM-style replacement or new-installation component for TB-6J series sleeve coupling assemblies requiring a size 6 finished bore flange.
Installation 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.
