Description
The TB Woods 10JES is a single-piece EPDM split sleeve insert engineered specifically for use with size 10 Sure-Flex Plus flexible jaw couplings. Designed as a direct replacement or new-installation coupling element, this insert provides reliable torque transmission while absorbing shock, vibration, and misalignment between connected shafts — making it an ideal choice for HVAC fans, blowers, pumps, and other mechanical drive applications.
Key Features
- Single-piece split sleeve design for easy installation and replacement without disturbing shaft alignment or connected equipment
- Manufactured from EPDM (Ethylene Propylene Diene Monomer) elastomer for excellent resistance to heat, ozone, and environmental aging
- Compatible exclusively with TB Woods size 10 Sure-Flex Plus coupler hubs
- Absorbs torsional shock and vibration to protect connected drive components
- Accommodates angular, parallel, and axial misalignment
- No lubrication required for maintenance-free operation
Application
The 10JES insert is the flexible element that connects the two hubs of a Sure-Flex Plus coupling assembly. The split sleeve construction allows the insert to be installed or removed radially — without moving shafts or hubs — minimizing downtime during maintenance. EPDM material makes this insert well-suited for HVAC mechanical rooms and outdoor environments where exposure to heat and ozone is a concern.
