Flexible shaft is an innovative old component in the modern mechanical domain. With flexible shafts various problems can be solved in a reliable and cost efficient way. It is often used in mechanical remote controls to move a slide or turn a valve in a distance or in a hazardous environment. On the other side, it gives freedom for grinding operations from heavy drives or for delicate work. The suhner group, a worldwide leader in flexible shaft manufacturing and with more than 100 years experience, has come up now with its new catalogue, which contains all the basic information and a wide selection of products to supply solutions in all flexible shaft applications. With that handbook it is easy to select the right flexible shafts for applications like medicine, machine building, home appliance and others. The selection considers the important design points for solutions like the transmittable torque, the bending radius or the torsion all deflection. All that points have to be answered to get a smooth running transmission of rotary power.
