TB Woods 6J-1 1/4 Flange

As a technician, you know that keeping high-performance equipment online requires components that can handle real-world stress. This TB Woods 6J-1 1/4 Flange is a Size 6 Type J Sure-Flex Plus coupler hub engineered from high-strength cast iron to deliver maximum stability in demanding HVACR applications. Designed for a 1-1/4 inch bore with a standard 1/4 x 1/8 inch keyseat, this bored-to-size flange ensures a precise fit for standard shafts without the need for additional machining. Utilizing the Sure-Flex Plus 4-way flexing action, it effectively isolates shaft misalignment and vibration while providing a notable 30% increase in torque capacity compared to previous generations. This means you can often drop down a size to save space without sacrificing power. This torsionally soft coupling component operates smoothly up to 6000 RPM, making it a reliable elastomeric coupling flange for motors, pumps, and compressors where downtime is not an option.

• Enhanced Torque Capacity: Features the Sure-Flex Plus design upgrade, offering 30% more torque and higher service factors.
• Cast Iron Durability: Constructed from high-strength cast iron for improved fatigue resistance compared to sintered or aluminum alternatives.
• Precision Bore: Factory-cut 1-1/4 inch bore with integrated 1/4 inch keyway for immediate, slip-fit shaft installation.
• Misalignment Compensation: Protects bearings and seals by absorbing parallel and angular misalignment as well as end float.
• Maintenance-Free: The non-lubricated design eliminates the mess and service intervals associated with gear or grid couplings.

• Can I use this flange with a Hytrel sleeve? No, Type J flanges are designed for use with EPDM or Neoprene sleeves. Hytrel sleeves require specifically rated flanges to handle different torsional wind-up characteristics.
• How do I check alignment with this hub? The outside diameter of the 6J flange is precision-machined, allowing you to use a straight-edge across the OD to verify parallel alignment quickly.
• Is a set screw included? Yes, these flanges typically come with one set screw positioned over the keyway to lock the hub securely to the shaft.
