T-Series (T-Flex)

ATRA-FLEX™, a U.S. Tsubaki Power Transmission, LLC brand, produces high-quality flexible couplings made in the USA for a wide range of industries and applications to solve your torque transmission and misalignment needs.

ATRA-FLEX T-Series Couplings

Reduce Cost of Maintenance and Downtime with T-Series Couplings

T5-EXPLODED-GB

For reliability and total low cost of ownership, customers turn to ATRA-FLEX flexible couplings. We are proud to provide high-quality couplings that have been proven to increase efficiency and productivity for industrial applications worldwide since 1980.

How T-Series Works

T-Series close coupled couplings consist of four parts. The ring hub, flex hub, insert, and drive ring. The ring hub and flex hub are installed on the shafts with the drive ring fitting over the flex hub. After coupling alignment, the insert is placed around the flex hub engaging the bottom lobes of the insert. The drive ring is then fitted over the insert engaging the top lobes of the insert. The drive ring is then fastened to the ring hub using high strength alloy steel socket head cap screws with high collar lock washers. The coupling will now transmit torque with silent, smooth reliable, maintenance free operation.

T-Series Features

  • Absorbs extreme torsional shock and vibration while accommodating angular, parallel, and axial misalignment without generating reactionary loads, significantly increasing bearing life.
  • Uniquely combines the stability of a compression type coupling with the safety of a shear coupling. In the event of a lockup, the insert will shear, minimizing the possibility of damaging your rotational equipment.
  • Allows up to 15″ shaft diameters and 1,570,000 in-lbs of torque in several configurations including: non-spacer, spacer, floating shaft, flywheel, limited-end float, among others.
  • No lubrication.
  • Reduced spare parts. The rugged polyurethane insert is the only spare part and can be inspected or replaced in minutes without having to move the equipment or the shaft hubs.
  • Withstands a temperature range from -60° to 350° Fahrenheit depending on insert type.
  • Wide range of inserts available to meet most torsional stiffness and torque requirements and offers very high resistance to chemicals and weather.
  • HD inserts available for 30% higher torque without changing any other components.
  • Nitrocarburized process is available for corrosion resistance as a cost-effective alternative to stainless steel.
