Tb Woods TB-9JES Sure-flex Sleeve Coupling Insert Size 9 Epdm

Product Description

The TB WOODS TB-9JES is a Size 9 Sure-Flex sleeve coupling insert made from EPDM rubber, designed for flexible jaw-style shaft couplings in power transmission systems. It handles a maximum torque of 2,340 in-lb and operates at speeds up to 3,750 RPM. The one-piece split design allows the insert to be installed and replaced without disconnecting the hubs, saving time during maintenance. The EPDM compound provides chemical and oil resistance, making it suitable for harsh industrial environments. Licensed HVAC technicians, millwrights, and industrial mechanics install this type of flex element when setting up or servicing coupled drive systems.

This insert fits Size 9 JES-flange Sure-Flex coupling hubs and is rated across a wide horsepower range: 3.71 hp at 100 RPM, 44.55 hp at 1,200 RPM, 66.83 hp at 1,800 RPM, and 133.66 hp at 3,600 RPM. Typical applications include blowers, compressors, conveyors, mixers, motors, and pumps in both commercial and industrial settings. The EPDM elastomer handles angular misalignment up to 1 degree and parallel misalignment up to 0.025 inches, while absorbing shock, vibration, and end float through four-way flexing action.

Key Features

• One-piece split construction allows insert replacement without hub disassembly
• EPDM rubber is chemical resistant and oil resistant for industrial environments
• Handles angular misalignment up to 1 degree and parallel misalignment up to 0.025 inches
• Four-way flexing action absorbs shock, misalignment, vibration, and end float
• Wide operating temperature range: -30 degrees F to 275 degrees F
• Torsional stiffness of 6,875 in-lb/rad for predictable drive performance

Compatibility

Designed for use with Size 9 JES-flange Sure-Flex sleeve coupling hubs. Suitable for power transmission applications involving blowers, compressors, conveyors, mixers, motors, and pumps.

Installation Notes

Installation is performed by millwrights, industrial mechanics, or qualified maintenance technicians. De-energize and lock out the drive system before servicing the coupling. The one-piece split design allows the insert to slide into place around the shaft without removing the hubs, but proper hub alignment should be verified before torque is applied to the drive. Follow applicable ANSI and OSHA machinery guarding requirements during installation and reassembly.
