ABSTRACT:
A short-stroke clamping element for exerting a clamping or holding force on a workpiece has a bar-like form with its length direction normal to the direction of the clamping force to be produced. There is an internal pressure space that is put under pressure for operation of the device. The pressure space is sealed off peripherally and extends essentially along the full length of the clamping element. At least one of the sides of the element forms a claiming face constituted by a wall that is able to be moved outwards by admitting compressed air to the pressure space.
