Accessories Vacuum Cups
General Guide & Overview
When it comes to material handling and gripping tasks in various industries, vacuum cups, also known as suction cups, are indispensable accessories.
Vacuum cups are manufactured using different elastomer materials such as Nitrile (NBR), Neoprene (CR, NEO, NE, N50), and Polyurethane (PUR), among others. Each material possesses unique properties such as hardness levels, temperature resistance, wear resistance, and oil/grease resistance.
Understanding the types of industrial suction cups available is crucial for selecting the most suitable option for specific applications. Flat vacuum suction cups provide stability and are ideal for handling flat or slightly curved nonporous surfaces. Oval suction cups are designed for thin and elongated surfaces, offering maximum holding force. Bellows suction cups are perfect for uneven or rough surfaces, flexible workpieces, or delicate operations.
Industrial vacuum suction cups function by creating a negative pressure or vacuum between the cup and the workpiece. This is achieved using vacuum generators such as vacuum pumps or electric vacuum generators. The vacuum cup's design and the level of vacuum determine the attachment time, release time, and holding force.
Types of Industrial Suction Cups
When it comes to material handling, different types of vacuum suction cups are available for various applications. Understanding their unique features and capabilities can help businesses make informed decisions about the most suitable suction cup for their needs.
Flat Vacuum Suction Cups
Flat vacuum suction cups are specifically designed to handle flat or slightly curved nonporous surfaces with stability and precision. Their flat shape allows for a large contact area, ensuring a secure grip. These suction cups are ideal for tasks that require holding items in place during processing, such as CNC machining or pick-and-place operations on smooth surfaces.
Oval Vacuum Suction Cups
Oval vacuum suction cups are perfect for handling thin and elongated surfaces. They can be found with both flat and bellowed lips. The flat-lipped oval suction cups provide maximum holding force, making them excellent for secure gripping of fragile or delicate objects. On the other hand, the bellowed-lipped oval suction cups offer additional flexibility, adapting to various shapes and contours. They are commonly used in industries such as packaging and electronics where precise and reliable handling is crucial.
Bellows Suction Cups
Bellows suction cups are specially designed for handling uneven or rough surfaces, flexible workpieces, and delicate operations. Their unique bellows structure allows for enhanced adaptability, enabling them to conform to irregular shapes and contours. Bellows suction cups are often preferred for applications involving materials like textiles, thin sheets, and irregularly shaped objects. Some bellows suction cups come with multiple bellows to ensure efficient handling of different materials without sacrificing stability and grip strength.
Additional Features
Some suction cups come with additional features to enhance performance and versatility. For example, suction cups may have a lip feature to prevent any leakage and maintain a reliable vacuum seal. Supporting ribs may also be incorporated into the suction cup design to increase holding force and stability during material handling tasks. Moreover, different sizes and shapes are available to accommodate a wide range of gripping needs, ensuring optimal performance in various industrial settings.
By understanding the different types of industrial suction cups, including flat vacuum suction cups, oval vacuum suction cups, and bellows suction cups, and their additional features, businesses can make informed decisions about which type of suction cup will best suit their specific material handling requirements. This knowledge enables companies to maximize efficiency, productivity, and safety in their operations while achieving reliable and secure gripping.

What are the different types of vacuum suction cups?
There are different types of vacuum suction cups available for various material handling applications. These include flat vacuum suction cups, oval suction cups, and bellows suction cups.
How do vacuum suction cups work?
Vacuum suction cups work by using vacuum generators, such as vacuum pumps or electric vacuum generators, to create a negative pressure or vacuum between the cup and the workpiece. This enables the cup to attach to the workpiece and maintain a vacuum to prevent air leakage.
What factors should be considered when selecting a vacuum cup?
When selecting a vacuum cup, it is important to consider the weight of the object being lifted, the surface area of the cup, and the required vacuum level. Proper matching of these factors ensures optimal grip and release performance.
