Description
The TB Woods 3JES is a single-piece EPDM split sleeve insert designed specifically for use with size 3 Sure-Flex Plus flexible jaw couplers. Engineered to deliver reliable torque transmission and vibration dampening in demanding HVAC and mechanical drive applications, this sleeve insert serves as the flexible element between the two coupler hubs, absorbing shock loads and compensating for minor shaft misalignment to protect connected equipment.
Key Features
- Single-piece split sleeve design allows installation and replacement without disturbing connected equipment or shaft alignment
- Manufactured from EPDM (ethylene propylene diene monomer) elastomer for excellent resistance to heat, ozone, weathering, and many chemicals
- Designed exclusively for TB Woods size 3 Sure-Flex Plus coupler hubs
- Provides flexible, resilient coupling element that absorbs vibration and dampens shock loads
- Compensates for angular, parallel, and axial shaft misalignment
- Drop-in replacement for worn or damaged sleeve inserts — no special tools required
- Helps extend the service life of motors, pumps, and driven equipment by reducing transmitted vibration
Application
The 3JES sleeve insert is the flexible wear element in the TB Woods Sure-Flex Plus coupling system, commonly used in HVAC fan and blower drives, pump drives, compressor drives, and other light-to-medium duty power transmission applications. The EPDM material is well suited for environments with exposure to heat and outdoor conditions, making it a popular choice in mechanical rooms and rooftop equipment installations.
