Description
The TB Woods 3JE is a single-piece EPDM solid sleeve insert designed specifically for use with Size 3 Sure-Flex Plus flexible couplers. Engineered as a direct replacement or spare element, this sleeve insert serves as the flexible, load-bearing interface between the two coupling hubs, absorbing shock, dampening vibration, and accommodating minor shaft misalignment in rotating equipment applications common to HVAC and mechanical systems.
Key Features
- Single-piece construction for simplified installation and replacement
- Manufactured from EPDM (Ethylene Propylene Diene Monomer) elastomer for excellent resistance to heat, ozone, and weathering
- Designed exclusively for Size 3 TB Woods Sure-Flex Plus couplers
- Solid sleeve design provides consistent torque transmission and reliable performance
- Absorbs shock loads and dampens torsional vibration to protect connected equipment
- Accommodates angular, parallel, and axial shaft misalignment
- Drop-in replacement element — no special tools required for installation
Material & Construction
- Elastomer material: EPDM (Ethylene Propylene Diene Monomer)
- EPDM compound offers superior resistance to heat aging, ozone, and environmental exposure
- Solid sleeve profile for uniform load distribution across the coupling interface
- Compatible with TB Woods Sure-Flex Plus Size 3 coupling hubs
Typical Applications
- HVAC fan and blower drive systems
- Pump and motor shaft connections
- Compressor drive couplings
- General industrial power transmission applications
- Replacement element for worn or damaged Sure-Flex Plus Size 3 couplings
Why Choose TB Woods Sure-Flex Plus
TB Woods Sure-Flex Plus couplings are a trusted standard in flexible jaw coupling technology, widely used across HVAC, pump, and industrial drive applications. The sleeve insert is the sacrificial wear element of the coupling — replacing it at regular intervals protects the coupling hubs and connected machinery from damage. Stocking a replacement 3JE sleeve ensures minimal downtime when scheduled or emergency maintenance is required.
