TF Flexible shafts The spring flexible shafts for the transmission of rotational motions are characterized by a big flexibility, a remarkable strenght and an exceptional endurance; they can function in continuous with a high speed and shock-damping is good. The application field is very wide: instruments remote control, transmission of a mechanical rotating power, connection of two not aligned elements, control of overhead parts, etc. They can be used in both directions of rotation. It is advisable to choose a left spring shaft to turn clockwise, and a right spring shaft to turn counterclockwise: the maximum torque is lower than 30%. Usually are available left spring shafts. The spring shafts are usually protected by a flexible steel sheating and have on the end part steel coupling terminals (complete fexible shaft). Available lenghts till 5 meters.
