TB Woods 11E Sleeve

The TB Woods 11E Sleeve is a professional-grade two-piece EPDM split sleeve designed for seamless integration with size 11 Sure-Flex Plus Couplers. Engineered for high-torque industrial applications, this split rubber insert utilizes a 2-piece design and a retaining ring to allow for rapid installation without the need to decouple the hubs from the shaft. This EPDM coupling element delivers a robust 5,890 in-lb torque rating and supports operating speeds up to 3,600 RPM, making it a standard for contractors managing pumps, blowers, and compressors. The specialized 4-way flexing action effectively dampens torsional vibration and accommodates up to 1 degree of angular misalignment and 0.032 inches of parallel misalignment. Optimized for durability, this elastomeric coupling insert operates efficiently in temperatures ranging from -30°F to +275°F, providing superior ozone and heat resistance in demanding HVACR and industrial environments.

Key Benefits:

• Reduced Downtime: The two-piece split design allows for fast replacement without moving the motor or the driven load.
• Shock Absorption: Advanced 4-way flexing action protects connected equipment by absorbing shock and misalignment.
• Maintenance-Free: These elastomeric sleeves require no lubrication, reducing long-term operational costs for contractors.
• High Performance: The Sure-Flex Plus series provides a 30% higher torque capacity than standard EPDM sleeves.

Common Questions:

• Can I use an 11E EPDM sleeve to replace a size 11 Hytrel sleeve? No, EPDM and Hytrel materials have different torque ratings and stiffness; always match the sleeve material to the original system specification to prevent coupling failure.
• Is the retaining ring included with the 11E insert? Yes, the 11E sleeve is a 2-piece assembly that includes the necessary retaining ring to secure the sleeve at high RPMs.
• How do I verify the size for my Sure-Flex coupler? Check the flange for an embossed size 11; this sleeve is exclusively compatible with size 11 flanges from TB Woods.
