Calculation of the holding forces
The calculation of holding forces can only be about theoretical values. In practical applications, many factors, such as the size and
shape of the suction cup, the surface finish and the rigidity of the workpiece (deformation) play a decisive role. That is the reason
why we recommend a safety factor (S) of at least 2. When swiveling workpieces during the handling task, a safety factor of 2.5 or
higher has to be used, in order to cope with the resulting turning forces.
