TB Woods 8E Insert

The TB Woods 8E Insert is a high-performance EPDM split sleeve coupling designed specifically for Sure-Flex Plus size 8 couplers. This two-piece split sleeve construction, featuring a retaining ring, is engineered for rapid installation and maintenance efficiency in heavy-duty HVACR and industrial drive systems. As a direct replacement for 022194 and 68514436419, the 8E delivers a 30% increase in torque capacity compared to legacy models, providing a rated torque of 1,475 in-lb. Its advanced EPDM material is optimized for temperature extremes ranging from -30°F to +275°F, making it resilient against heat and ozone while ensuring torsional flexibility. The 4-way flexing action effectively absorbs angular misalignment up to 1°, parallel misalignment up to 0.020 inches, and end float, which significantly reduces bearing loads and vibration in the drive train. Designed for speeds up to 4500 RPM, this elastomeric coupling element requires no lubrication, ensuring clean and reliable operation for critical motor-to-pump or fan applications.

• Optimized Compatibility: Direct replacement for 022194 and 68514436419, ensuring a precision fit for all size 8 Sure-Flex Plus flanges.
• Enhanced Durability: The Sure-Flex Plus 8E EPDM compound offers superior resistance to weathering and heat compared to standard neoprene inserts.
• Shock Absorption: Superior torsional wind-up capabilities dampen vibration and protect sensitive equipment from sudden load changes.
• Reduced Maintenance: The split sleeve design allows for replacement without moving the hubs or the motor, minimizing system downtime.

• Can I use an 8E insert to replace a standard size 8 sleeve? Yes, the 8E EPDM split sleeve is backward compatible with existing Sure-Flex flanges and provides a significant upgrade in torque rating and service life.
• When should I choose EPDM over Neoprene for my coupling? EPDM is preferred for general industrial use, high-heat environments (up to 275°F), and outdoor applications due to its ozone resistance. However, if the environment involves oil or petroleum exposure, a Neoprene insert is recommended.
• What does the retaining ring do in the 8E assembly? The retaining ring is critical for two-piece split sleeves; it secures the split segments together during high-speed rotation to maintain balance and structural integrity up to 4500 RPM.
