TB Woods 3JE Insert

The TB Woods 3JE Insert is a critical elastomeric component engineered for high-performance power transmission in Sure-Flex Plus size 3 coupling assemblies. Constructed from high-grade EPDM rubber, this one-piece solid sleeve provides a maintenance-free solution for absorbing severe shock, vibration, and 4-way misalignment. Designed for rigorous industrial environments, the 3JE EPDM sleeve offers excellent resistance to heat, steam, and chemicals, ensuring operational stability across a temperature range of -30°F to +275°F. With a maximum speed of 9200 RPM and a rated torque capacity of 78 in-lb, this robust insert facilitates smooth torque transfer while protecting connected equipment from premature wear caused by shaft misalignment. This EPDM solid sleeve insert is ideal for centrifugal pumps, fans, and compressors where torsional flexibility and vibration damping are required for reliable drivetrain performance. By utilizing the TB Woods 3J, technicians can achieve optimal alignment tolerance, handling up to 1 degree of angular misalignment and 0.010 inches of parallel misalignment without the need for lubrication.

• Shock Absorption: Features a 4-way flexing action that neutralizes torsional shock and prevents damage to motor bearings and driven equipment.
• Chemical Resistance: The EPDM material is highly resistant to indoor and outdoor weathering, moisture, and common industrial chemicals.
• Maintenance-Free: Eliminates the requirement for grease or consistent monitoring, as the elastomeric design requires no lubrication.
• High Speed Stability: Balanced for precision operation at speeds up to 9200 RPM, making it suitable for high-speed HVACR applications.
• Reliable Fit: Specifically molded for Sure-Flex Plus size 3 flanges, ensuring a secure, slip-free interface under high-torque loads.

Is the 3JE sleeve compatible with older Sure-Flex flanges?
Yes, the Sure-Flex Plus 3JE is 100% retrofittable to existing industry-standard flanges, allowing for a direct upgrade to the 30% higher torque capacity offered by the Plus series.

What is the difference between EPDM and Neoprene inserts?
While both offer the same 78 in-lb torque rating for size 3, EPDM is preferred for its superior heat and chemical resistance, whereas Neoprene is generally selected for applications involving oil exposure.

When should I use a solid sleeve versus a split sleeve?
The one-piece solid sleeve (JE) is the standard choice for new assemblies with accessible shafts, providing maximum structural integrity for the coupling element.
