TB Woods 12E Insert

When your Sure-Flex Plus size 12 system requires a field-serviceable elastomer, the TB Woods 12E insert delivers the highest torque density in its class. This EPDM split sleeve coupling is specifically engineered for high-demand HVACR and industrial pump applications where downtime is not an option. Unlike single-piece units, the two-piece 12E sleeve features a split design with a steel retaining ring, allowing for rapid installation or replacement without having to disturb the alignment of your motor or driven equipment.

The Sure-Flex Plus 12E is rated for a maximum torque of 9,360 in-lbs and can handle speeds up to 2,800 RPM. Its 4-way flexing action absorbs angular misalignment up to 1° and parallel misalignment up to 0.032 inches, significantly reducing radial loads on your bearings. The proprietary EPDM compound is optimized for a wide thermal operating range of -30°F to +275°F, making it ideal for standard coupling hubs and spacer flanges alike. This insert is a direct drop-in for any size 12 E-type coupling assembly, providing 30% more torque capacity than older generation sleeves.

• Rapid Field Servicing: The two-piece split sleeve with retaining ring allows for installation without moving the hubs or heavy machinery.
• Torsional Flexibility: Provides 7° to 21° of torsional wind-up to dampen shock loads and protect sensitive gearboxes.
• Low Maintenance: Requires zero lubrication and is resistant to dirt, moisture, and common industrial contaminants.
• Interchangeable Design: Fully compatible with existing TB Woods Sure-Flex flanges for a seamless performance upgrade.

• Can I use the 12E insert to replace a solid JE sleeve? Yes, the 12E is a two-piece alternative to the 12JE. It provides the same EPDM material performance but adds the convenience of a split-sleeve design for easier replacement.
• Is the retaining ring included with the 12E sleeve? Yes, the 12E EPDM insert ships with the necessary steel retaining ring to secure the two halves during operation at high speeds.
• What is the difference between EPDM and Neoprene for size 12? EPDM (12E) is the standard for most HVACR applications due to its superior temperature range and environmental resistance, whereas Neoprene (12N) is preferred for applications involving significant oil or petroleum exposure.
