KAflex® maintenance-free,
non-lubricated driveshaft.

Helicopter flight maneuvers generate high misalignment between the engine and the transmission, which must be accommodated by the connecting driveshaft. Such driveshafts, which rotate at speeds over 6000 RPM, often incorporate grease lubrication and seals. Designs of this type are susceptible to loss of lubrication, which results in overheating and possible failure, a major safety concern.

The KAflex driveshaft is a mechanical drive coupling which requires no lubrication or seals, and transmits power while accommodating high angular misalignment and length change through the use of flexible rectangular frames. These frames are bolted together at the corners in a truss-like arrangement, which are attached to shaft end fittings to allow for drop-in installation in the drive line. A fail-safe feature enables the coupling to continue to transmit power even in the unlikely event of a failure in a load carrying member.

KAflex driveshafts are custom designed for specific applications and selected because they offer superior, maintenance-free performance with extended "on condition" service-life, resulting in unequaled reliability, increased readiness and cost effectiveness. They are supplied both as individual couplings or as complete driveshafts.
