Bellows Suction Cups

Bellows vacuum cups are used when it is necessary to compensate for varying workpiece heights, to handle parts with uneven (concave, convex, or textured) surfaces, or easily damaged parts. A lifting effect during evacuation can be used to help separate a top sheet from those stacked below. Bellows suction cups can conform to curved or uneven workpieces such as pipes, bottles, containers, cylinders, car body components, flexing cardboard boxes, etc. Bellows vacuum cups provide height compensation and a ball-joint motion through a limited angular range.

Bellows vacuum cups have a relatively wide sealing lip that lays against the workpiece surface without scrubbing radially outward as the cup collapses under vacuum. This helps prevent the marring of highly finished surfaces such as injection molded plastic parts or for delicate item
