TB Woods 6J-7/8 Flange

The TB Woods 6J-7/8 flange is a precision-engineered Sure-Flex Plus coupler flange designed for high-torque mechanical power transmission in industrial HVACR applications. Cast from high strength cast iron, this Size 6 Type J flange is bored-to-size (BTS) for a standard 7/8" shaft, featuring a 3/16" x 3/32" keyseat for secure power transfer. Engineers and technicians rely on the 4-way flexing action of the Sure-Flex system to absorb shock, vibration, and end float, significantly reducing stress on connected pumps and motors. The 6J-7/8 fixed bore flange is 100% compatible with EPDM and Neoprene sleeves, offering a maintenance-free solution that requires no lubrication. Its precision-machined face simplifies alignment tasks, allowing the use of a simple straightedge for rapid field installation. When your application demands a robust shaft coupling flange with a 6,000 RPM maximum speed rating and a 585 in-lb torque capacity, this BTS component ensures reliable performance under heavy operational loads.

• High-Strength Construction: Manufactured from premium cast iron to handle the increased power density of modern Sure-Flex Plus systems.
• Vibration Dampening: Integrated 4-way flexing action effectively isolates torsional vibration and protects sensitive motor bearings.
• Simplified Alignment: Precision-machined flange surfaces allow for accurate parallel and angular alignment without specialized laser tools.
• Ease of Installation: The bored-to-size 7/8 inch inner diameter ensures a slip-fit on standard shafts with dual setscrews (one over the keyway and one at 90 degrees) for maximum retention.

• What sleeve materials are compatible with the 6J-7/8? This Type J flange is designed for use with EPDM and Neoprene sleeves. It should not be used with Hytrel sleeves, which require Type S or C flanges.
• Is lubrication required during maintenance? No. The elastomeric design of the TB Woods 6J series eliminates the need for grease, making it ideal for clean-room or food-grade HVACR environments.
• How do I verify alignment? You can check parallel alignment by placing a straightedge across the outside diameter of the 4-inch flanges at several points around the perimeter.
