Pneumatic Suction Cups

Pneumatic suction cups are devices that use negative fluid and gas pressure to act as grippers in automated or manual handling applications. They can help you move everything from pipes and sheet metal to bricks, bottles and bags in many industries including food, packaging, metalworking and electronics.




Pneumatic suction cups can be modelled so they fit unusual shapes and are constructed from materials such as Silicon, Nitrile Rubber (NBR), Fluorine etc.




How do pneumatic suction cups work?




When a suction cup contacts the surface of an object, it activates a vacuum generator (such as a blower, vacuum ejector or vacuum pump) that draws air from the space between the cup and the item. As soon as the atmospheric pressure is greater than the pressure between the object and the cup, atmospheric pressure presses the suction cup against the item, holding it firmly.




Types of pneumatic suction cups




Pneumatic suction cups come in two general shapes: flat (suited for handling workpieces with flat or slightly curved surfaces) and bellows (suited to handle parts with uneven surfaces).
