TB Woods 6J-1 3/8 Flange

The TB Woods 6J-1 3/8 Flange is a heavy-duty, high-strength cast iron flange designed specifically for Sure-Flex Plus size 6 couplings. This bored-to-size (BTS) flange features a precision-machined 1-3/8 inch bore with a standard 5/16" x 5/32" keyseat, ensuring a secure, slip-fit connection on standard motor and pump shafts. Engineered for torsional flexibility, this Type J coupling flange utilizes a 4-way flexing action to absorb shock, vibration, and end float, significantly reducing stress on connected equipment bearings. With a max RPM of 6000 and a torque capacity of 585 in-lbs (when used with EPDM or Neoprene sleeves), it provides a low-maintenance solution for HVACR pump coupling and power transmission. The precision-machined outside diameter allows for quick alignment checks using a straightedge, eliminating the need for specialized tools in the field. This component is compatible with all Sure-Flex Plus sleeves except Hytrel, making it a versatile choice for direct-drive motor applications.

• High-Strength Cast Iron Construction: Delivers superior durability and handles high-torque loads without the risk of fracture common in lighter materials.
• Maintenance-Free Performance: The wrap-around design eliminates the need for lubrication, reducing operational downtime and field service costs.
• Precision Machined Face: Facilitates rapid alignment using simple calipers or a straightedge, ensuring optimal concentricity and reduced bearing wear.
• Interchangeable Design: Compatible with existing Sure-Flex Plus sleeve elements, allowing for seamless integration into industrial pump drives and fan systems.

• Can I use this flange with a Hytrel sleeve? No, Type J flanges are designed for use with EPDM and Neoprene sleeves; Hytrel sleeves require Type S or SC flanges due to different torque ratings and stiffness.
• Does it include the setscrews? Yes, this flange is supplied with one setscrew positioned over the keyway and a second at 90 degrees for a secure lock on the shaft.
• What is the maximum misalignment it can handle? When properly installed with a rubber sleeve, it accommodates up to 1 degree of angular misalignment and 0.015" of parallel misalignment.
