TB Woods 9JES Insert

The TB Woods 9JES Insert is a professional-grade, single-piece EPDM split sleeve insert engineered specifically for size 9 Sure-Flex Plus couplers. This high-performance elastomer element is designed to handle the rigorous demands of industrial pump and motor applications, providing a torque rating of 2,340 in-lbs and a maximum speed of 3,750 RPM. Utilizing a split sleeve construction, the 9JES allows for rapid installation and replacement without the need to disturb connected equipment or remove hubs from the shafts, significantly reducing downtime during routine maintenance. The EPDM rubber material offers a broad operating temperature range from -30°F to 275°F, ensuring reliable 4-way flexing action that absorbs torsional shock, vibration, and accommodates up to 1° of angular misalignment and 0.025 inches of parallel offset. This elastomeric coupling insert requires no lubrication, making it an ideal choice for clean-room or wash-down environments where power transmission efficiency and system longevity are critical.

• Split Design for Fast Retrofitting: The one-piece split construction allows for easy replacement in existing Sure-Flex Plus assemblies without decoupling the flanges.
• Broad Environmental Resilience: High-grade EPDM material provides superior resistance to heat, ozone, and atmospheric aging in demanding HVACR environments.
• Shock and Vibration Dampening: The elastic properties of the 9JES sleeve effectively isolate torsional vibration, protecting sensitive motor and pump bearings.
• High Torque Capacity: Designed to offer up to 30% higher torque capacity compared to legacy designs, supporting up to 134 HP at 3,600 RPM.

What is the difference between the 9J and 9JES inserts?
The 9J is a solid one-piece sleeve requiring equipment separation for installation, while the 9JES features a split design that allows for wrap-around installation on existing setups, making it the preferred choice for field repairs.

Can I use an EPDM insert in oily environments?
While EPDM rubber is excellent for high temperatures and outdoor exposure, it is not recommended for applications involving constant oil or grease contact. For those conditions, a Neoprene (9JNS) or Hytrel insert should be utilized.

Do I need special tools to align a size 9 Sure-Flex coupler?
No, TB Woods designs these for simple installation. Proper alignment of the 9JES insert can typically be verified using a standard straight-edge and feeler gauges across the precision-machined flange surfaces.
