KAflex Drive Systems

Aerospace drive system applications present some of the most challenging and demanding power transmission requirements for flexible coupling elements. In an effort to avoid potential drive shaft problems, these flight-critical applications earned the Kamatics’ KAflex® and Tufflex® driveshaft systems their pedigree and reputation for safety that our drive shaft suppliers are looking for. For close to four decades, our maintenance-free couplings have been the first choice for helicopter main-shaft and tail rotor driveline locations; applications where failure is not an option as component malfunction can mean loss of life.
