Festo STAF Stopper Cylinder

Under impact force we understand the maximum of a force-time curve during impact/braking of the moveable mass. It is effective vertical to the movement axis of the piston rod. If one regards the elastic components as linear springs, the permitted impact energy can be calculated from the permitted impact force. This serves for selecting the correct stopper.

The stopper must not switch under this force. Depending on the mass to be stopped, it may be advisable to provide an elastic buffer in order to cushion the impact, to reduce noise and to optimize the impact energy.
