TB Woods 6J-1 Flange

The TB Woods 6J-1 Flange is a critical power transmission component designed for high-stress HVACR applications, including industrial pump couplings and commercial blower assemblies. This Size 6 Type J Sure-Flex Plus flange is engineered from high-strength cast iron, providing superior durability and vibration dampening compared to standard sintered metal alternatives. It features a precision-machined 1-inch bore and a standard 1/4" x 1/8" keyseat, ensuring a secure, slip-fit connection on standard motor and driven shafts.

Built to handle a maximum speed of 6000 RPM, the 6J-1 coupler flange is fully compatible with EPDM, Neoprene, and Hytrel sleeves, allowing for a versatile 4-way flexing action that manages angular misalignment and parallel offset. The precision-machined outside diameter serves as a reliable reference surface, enabling technicians to verify shaft alignment using only a straightedge, eliminating the need for specialized laser tools in the field. This fixed bore coupling also includes a primary setscrew positioned directly over the keyway and a second setscrew at a 90-degree offset to maintain maximum radial security during high-torque operation.

• Durable Construction: High-strength cast iron provides excellent torsional rigidity and resistance to fatigue in continuous-duty HVACR systems.
• Simplified Alignment: Precision-machined flange faces allow for rapid visual and manual alignment checks, reducing installation time.
• Enhanced Torque Capacity: Designed for Sure-Flex Plus systems, supporting higher torque ratings and improved service life over legacy designs.
• Maintenance-Free Operation: The non-lubricated design eliminates messy grease requirements and reduces long-term maintenance overhead.

• What sleeve materials are compatible with the 6J-1 flange? This flange is designed to work with standard EPDM (JE/JES), Neoprene (JN/JNS), and high-torque Hytrel (H/HS) sleeves within the Size 6 series.
• Does this flange require special tools for installation? No, the bored-to-size design fits standard 1-inch shafts. You only need a standard hex key for the setscrews and a straightedge for alignment.
• Can this flange be used in high-heat environments? Yes, when paired with an appropriate EPDM or Hytrel sleeve, the assembly can operate effectively in temperatures ranging from -30°F to +275°F.
