SMC ZP vacuum buffers connect vacuum pads to robotic arms and other lifting equipment and compensate for workpieces of different heights. Also called buffer assemblies, they connect with compatible SMC brand vacuum pads.

Schmalz FSTE vacuum buffers handle workpieces with different heights, such as curved metal sheets, and sensitive workpieces like glass sheets. Also called spring plungers, they consist of plunger rods with an integrated vacuum feed, lower damping springs to ensure soft placement of items, and threaded connections for suction cups. They are used for applications that require height compensation, or when working with delicate materials.
