* The gripping force is the arithmetic sum of the individual forces created at the fingers at “F” distance at max pressure.
* Closing and opening times are purely the times that the base jaws are in motion. Valve switching, hose filling, PLC/CNC reactions, and other potential delays are not included and must be taken into consideration when determining cycle times.
