TB Woods 9JE Insert

The TB Woods 9JE Insert is an industrial-grade, single piece EPDM solid sleeve designed specifically for Sure-Flex Plus size 9 couplers. Engineered for high-stress power transmission, this elastomeric coupling insert utilizes a 4-way flexing action to effectively absorb shock, vibration, and end float. The EPDM rubber material offers excellent resistance to heat and ozone, maintaining performance in temperatures ranging from -30°F to +275°F. With a rated torque of 2,340 in-lbs and a maximum speed of 3,750 RPM, this sleeve provides a 30% increase in torque capacity compared to previous generations. The solid, one-piece construction ensures a secure fit within Sure-Flex Plus flanges, eliminating the need for lubrication or periodic maintenance. This component is 100% interchangeable with existing industry-standard flanges, allowing for a direct drop-in replacement that minimizes radial bearing loads and protects connected equipment from parallel and angular misalignment.

• High Torque Density: Optimized EPDM compound provides a 2,340 in-lb torque rating for demanding pump and motor applications.
• Superior Misalignment Capacity: Accommodates up to 1° of angular misalignment and 0.025 inches of parallel offset without premature wear.
• Maintenance-Free Operation: The solid sleeve design requires no lubrication, seals, or gaskets, reducing long-term overhead.
• Damping Performance: High torsional flexibility (6,875 in-lbs/rad stiffness) dampens vibration to extend the service life of bearings and shafts.

Is the 9JE insert compatible with older Sure-Flex flanges?
Yes, the 9JE Sure-Flex Plus sleeve is fully retrofittable to existing size 9 flanges, allowing you to upgrade torque capacity without replacing the entire coupling assembly.

Can this insert handle chemical exposure?
The EPDM material is highly resistant to water and variety of chemicals, though it is not recommended for applications involving constant hydrocarbon or oil contact.

How do I verify the correct fit for my size 9 coupling?
The 9JE insert features a 6-inch outside diameter and a 3-inch width, specifically designed to seat into size 9 J, S, or B type flanges.
