TB Woods 5JN Insert

The TB Woods 5JN Insert is a single piece neoprene solid sleeve specifically engineered for size 5 Sure-Flex Plus Couplers. This flexible coupling insert is designed for high-torque power transmission, offering superior torsional flexibility and the ability to absorb shock loads while compensating for angular and parallel misalignment. Unlike standard EPDM sleeves, this neoprene coupling sleeve provides enhanced resistance to oil and chemicals, making it the industry standard for demanding HVAC and industrial pump applications where environmental contaminants are present. The solid one-piece design ensures consistent performance and simplifies installation, effectively dampening vibration to extend the service life of connected motors and driven equipment.

• Enhanced Chemical Resistance: Neoprene construction offers superior durability in environments exposed to oils, greases, and various solvents.
• Superior Misalignment Compensation: Absorbs up to 1 degree of angular misalignment and 0.015 inches of parallel misalignment without compromising structural integrity.
• High Torque Capacity: Precision molded to fit TB Woods size 5 flanges, ensuring 4-way flexing action that handles high-stress load fluctuations.
• Zero Maintenance Design: Operates without the need for lubrication, reducing downtime and lowering the total cost of ownership for commercial mechanical systems.
• Durable Torsional Damping: Protects sensitive drivetrain components by mitigating resonant vibrations and mechanical shock.

What is the maximum RPM rating for the TB Woods 5JN sleeve?
The TB Woods 5JN Insert is rated for speeds up to 7,600 RPM when paired with appropriately balanced size 5 Sure-Flex flanges, though actual operating speeds should be verified against the specific motor and load requirements.

Can I use a 5JN Neoprene insert to replace a standard 5E EPDM sleeve?
Yes, the TB Woods 5JN is a direct dimensional replacement for the 5E, but it is preferred for oily environments where EPDM would typically swell or degrade prematurely.

How do I identify when a 5JN insert requires replacement?
Inspect the sleeve for visible backing out from the flanges, excessive rubber dust (fretting), or significant hardening of the neoprene material, which indicates the coupling has reached its service life limit.
