T-FLEX ® MILLENNIUM ® M-SERIES T-SERIES

The T-Series uniquely transmits torque while accommodating misalignment without generating reactionary loads, increasing bearing life. Torque transmission capabilities up to 2,041,000 in.-lbs and shaft diameters to 20.00”. Coupling types range from close The ATRA-FLEX ® M-Series flexible couplings are designed to accommodate a wide range of industrial applications, offering a torque capacity up to 3,610,000 in-lbs and can handle shaft diameters up to 16 inches. These couplings feature a unique twist-and-lock ring that eliminates the need for fasteners or special tools, facilitating easy installation and maintenance. The rugged polyurethane insert effectively absorbs torsional and reversing applications. The T- Series has no metal- to-metal contact and in the event of a lock up, the insert will shear without damaging the connected equipment. Lubrication free and access to the insert without moving the connected equipment means replacing inserts with ease in minutes vs hours compared to lubricated coupling maintenance. shock and vibration while accommodating angular, parallel, and axial misalignment, thereby enhancing equipment longevity. Additionally, the couplings operate lubrication free, have no metal-to-metal contact and can withstand temperatures ranging from -60°F to 350°F. For applications requiring corrosion resistance, options include stainless steel components or a cost-effective nitrocarburized process known as OnyxShield ™ , as an alternative. Learn More at
