TB Woods 6JES Insert

Installing a TB Woods 6JES Insert is the standard procedure for technicians maintaining high-performance Sure-Flex Plus Couplers. This single piece EPDM split sleeve insert is engineered as the primary replacement for 68514436701, offering a 30% increase in torque capacity over standard models. The split sleeve design allows for rapid installation and field replacement without needing to disassemble coupling flanges or move connected equipment, significantly reducing downtime. Constructed from industrial-grade EPDM rubber, this elastomeric coupling element provides excellent 4-way flexing action, effectively absorbing parallel misalignment up to 0.015 inches and angular misalignment up to 1°.

The Sure-Flex Plus 6JES is specifically designed for size 6 coupling configurations used in demanding HVACR pump and compressor applications. It maintains a torque rating of 585 in-lbs and is rated for speeds up to 6,000 RPM. The material properties of the EPDM insert ensure reliable performance across a broad temperature range from -30°F to +275°F, making it resilient against environmental factors like ozone and moisture. For contractors looking to optimize power transmission efficiency, this TB Woods 6JES ensures a clean, quiet, and lubrication-free operation.

• Reduced Downtime: The split sleeve architecture allows for "drop-in" replacement without pulling the motor or pump.
• Equipment Protection: High torsional flexibility dampens shock loads and vibration, extending the life of your bearings and seals.
• Chemical & Thermal Resistance: High-grade EPDM is ideal for outdoor or high-heat environments where standard rubber fails.
• Interchangeability: Fully compatible with existing Sure-Flex flanges, eliminating the need for full system upgrades.

Is the 6JES compatible with older 6E sleeves?
Yes, the 6JES is the direct Sure-Flex Plus upgrade for the older 6E series, offering improved torque density and a split sleeve for easier maintenance.

What is the maximum torque capacity of this insert?
This Size 6 EPDM sleeve is rated for 585 in-lbs of torque, which is a 30% increase over previous iterations.

Can I use this in an oil-laden environment?
No, EPDM is not recommended for applications where it will stay in contact with petroleum products. In those cases, a Neoprene (JNS) or Hytrel (H) sleeve should be used.
