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.
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.
A-Series is the original patented ATRA-FLEX design. The A-Series close coupled couplings consist of four parts, two flex hubs, insert, and ring. The flex hubs are installed on the shafts with the ring fitted over the flex hub. After coupling alignment, the insert is placed around the flex hubs engaging with the bottom lobes of the insert. The ring is then fitted over and engaged with the insert. No fasteners or special tooling is required. In the event of a lockup, the insert will shear, minimizing the possibility of damaging your rotational equipment. The rugged polyurethane insert is the only spare part and can be replaced and inspected in minutes without having to move the equipment or the shaft hubs. The inserts are available in a range of hardness to meet most torsional stiffness and torque requirements and offer very high resistance to chemicals and temperature shifts.
