The workpiece dictates the gripping principle
Weight, shape, surface, sensitivity, dimensional variation and available contact surfaces determine whether a parallel, vacuum, soft or special gripper is best.
Stroke and force
Stroke must cover the actual product range with margin, while force is determined by mass, acceleration, coefficient of friction and the safety factor.
Electric or pneumatic
Electric grippers offer programmable position and force, while pneumatic systems remain simple, fast and robust when compressed-air infrastructure is already available.
Spare fingers and consumables
For long-term use, the availability of replacement fingers, seals, membranes and other consumable parts is equally important.
