What are vacuum suction cups?
Vacuum pads, or vacuum suction cups, are the final components of a vacuum system used to grip, lift and transport workpieces by means of negative pressure.
They provide a simple, efficient, and cost-effective solution for handling a wide variety of parts in industrial environments, offering an alternative to more complex and expensive mechanical handling systems.
What are the advantages of choosing vacuum suction cups?
Vacuum suction cups form the end element of a vacuum system and create a simple yet highly efficient method for lifting and transporting a wide range of components.
They represent an effective alternative to more complicated and costly handling methods, helping to streamline automation processes while maintaining reliable and secure gripping performance.
What types of industrial vacuum cups does SMC offer?
To ensure secure gripping of a workpiece, it is essential to select vacuum suction cups according to the properties of the part being handled and the specific requirements of each application.
In our catalogue, you will find vacuum suction cups in a variety of designs, connection orientations, shapes and materials to suit virtually any application including automated handling systems such as a vacuum gripper robot.
Our vacuum suction cups have been developed to meet all your requirements:
- Flat vacuum suction cups: For handling flat parts in general-purpose applications.
- Bellows suction cups: Used to compensate for height differences or to transport parts with inclined or sloping surfaces.
- Oval vacuum suction cups: Suitable when the workpiece has a narrow suction surface or is very long and requires precise positioning.
- Nozzle-shaped suction cups: Ideal for high-precision handling of small and lightweight components.
- Sponge-type suction cups: Perfect for use on irregular or uneven surfaces where vacuum leakage may occur due to difficult gripping conditions.
- Non-contact vacuum grippers: Ideal for gentle handling of parts of varying sizes, materials and shapes. Suitable for thin, porous, perforated or pressure-sensitive workpieces.
What safety considerations apply when using vacuum suction cups in industrial environments?
Most manufacturers apply a safety factor of 2 for horizontal vacuum handling systems and 4 for vertical systems. However, these values serve only as general guidelines and often do not take into account important variables such as vacuum leakage, workpiece porosity, or acceleration and deceleration during transfer.
Experience undoubtedly plays a crucial role in this context. At SMC, we have built extensive knowledge and decades of expertise in vacuum solutions. This experience has led us to conclude that higher safety factors should be applied to ensure the reliability of a vacuum system across all industries.
For this reason, we use a safety factor of 4 for horizontal applications and recommend a higher margin of 8 for vertical applications.
Take advantage of our specialists’ recommendations to configure a vacuum system that is both safe and energy-efficient.
What should be considered when selecting vacuum suction cups?
Industrial vacuum pads play a key role in optimising the efficiency of a vacuum system.
Correct selection is essential to maximise system performance under different operating conditions and across various applications.
The choice of vacuum suction cups depends primarily on the following factors:
- Mass of the workpiece
- Position of the workpiece (horizontal or vertical)
- Geometrical shape of the workpiece
- Material compatibility
- Surface roughness and porosity
- Accelerations and decelerations (generated inertia)
With the help of our practical selection guide, you can quickly and easily find the right vacuum suction cups for your application.
