TB Woods 4JE Insert

The TB Woods 4JE flange insert is a single-piece, solid construction EPDM sleeve specifically engineered for Sure-Flex Plus size 4 couplings. This high-performance elastomer provides excellent torsional flexibility and is designed to handle angular misalignment, parallel offset, and axial movement in power transmission systems. As a veteran-grade elastomeric coupling insert, the 4JE is ideal for applications involving high humidity or atmospheric spray, offering superior resistance to water and heat compared to standard neoprene alternatives. When performing a Sure-Flex Plus coupling replacement, utilizing the 4JE ensures optimal vibration dampening and shock load protection, effectively isolating the motor from the driven equipment. The solid sleeve design facilitates a simplified TB Woods 4JE installation, allowing for quick maintenance cycles without the need for lubrication. This size 4 EPDM insert is rated for a wide operating temperature range, maintaining structural integrity and material memory during continuous duty cycles in commercial and industrial HVACR environments.

• Superior Torsional Flexibility: Absorbs shock loads and dampens motor vibration to extend the service life of bearings and seals.
• High Resistance: EPDM material provides excellent resistance to heat, ozone, and moisture, making it suitable for demanding mechanical rooms.
• Four-Way Flexing Action: Accommodates all types of misalignment including angular, parallel, and end float without mechanical wear.
• Interchangeability: Fully compatible with existing size 4 TB Woods Sure-Flex flanges for seamless field integration.
• Low Maintenance: No lubrication or periodic greasing is required, reducing long-term operational costs for contractors.

What is the difference between EPDM and Neoprene in size 4 inserts?
EPDM (JE) inserts like the 4JE offer better heat and moisture resistance and are generally the standard for HVACR applications, whereas Neoprene (JN) is better for environments with high oil or grease exposure.

How do I identify if I need a solid (JE) or split (JES) sleeve?
Solid sleeves like the 4JE are used when the flanges can be moved enough to slide the insert over the shaft during installation. Split sleeves are used for "close-coupled" installations where the equipment cannot be moved.

Can I use a 4JE insert with flanges from other brands?
The TB Woods 4JE is specifically designed for Sure-Flex Plus size 4 coupling flanges. While some dimensions may appear similar, performance and fitment are only documented for TB Woods assemblies.
