What are vacuum suction cups?
Vacuum cups are the end components of a vacuum system used for gripping, lifting and handling workpieces through negative pressure.
They provide a simple, efficient and cost-effective handling solution for a wide variety of industrial applications, offering an alternative to more complex and expensive mechanical handling systems.
What are the benefits of using vacuum cups in industrial applications?
Vacuum cups are the final element of a vacuum system and form an efficient and straightforward solution for handling a wide range of workpieces.
They represent a practical alternative to more complicated and costly handling methods, helping to simplify automation processes while maintaining reliable performance.
What types of vacuum suction cups and vacuum grippers does SMC offer?
The properties of the workpiece to be handled are always the starting point when selecting the most suitable vacuum suction cups for each application.
In our catalogue, you will find vacuum cups and vacuum grippers available in various designs and connection orientations, shapes, materials and configurations for a wide range of applications.
Our vacuum suction cups are designed to meet all your requirements:
- Flat vacuum suction cups: For handling flat workpieces in general applications.
- Bellows suction cups: Used to compensate for height differences or to transport workpieces 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 suction cups: Ideal for high-precision handling of small and lightweight workpieces.
- Sponge suction cups: Perfect for use on irregular or uneven surfaces where vacuum loss may occur due to difficult gripping conditions.
- Non-contact vacuum grippers: Ideal for the gentle handling of workpieces of different sizes, materials and shapes. Suitable for thin, porous, perforated or pressure-sensitive parts.
What safety aspects should be considered when using vacuum suction cups in industrial environments?
Most manufacturers use a safety factor of 2 for horizontal vacuum handling systems and 4 for vertical systems. However, these values are only guidelines and often do not take into account important variables such as vacuum loss due to leakage or the porosity of the workpieces.
Experience undoubtedly plays a crucial role in this context. At SMC, we have accumulated extensive knowledge and decades of expertise in vacuum solutions. Based on this experience, we recommend applying higher safety factors 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?
Vacuum suction cups play a key role in optimising the efficiency of a vacuum system.
Correct selection of vacuum suction cups is essential to maximise system performance under different operating conditions and across various applications.
The choice of vacuum suction cups and vacuum grippers mainly depends on the following factors:
- Mass of the workpiece to be handled
- 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 tool, you can quickly and easily find the right vacuum suction cups for your application.
