Flexible Drive Systems

Kaman Specialty Bearings Flexible Drive Systems

Solutions to the most challenging power transmission applications.

Our proprietary KAflex® and Tufflex® flexible shafts and coupling systems are frequently selected for critical rotating applications that demand a level of performance and safety that cannot be achieved with conventional greased coupling systems or standard flex-element couplings. Extreme torque, excessive angular misalignment, and high operating speeds are just a few of the parameters that make customers turn to Kamatics Flexible Drive Systems.

Flexible Drive System for Aerospace

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. 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.
