Product Description:
The VASB series consists of bellows-type vacuum suction cups specifically designed to ensure reliable gripping and handling of workpieces that have uneven, curved, or inclined surfaces. Unlike traditional flat suction cups, the unique 1.5-fold bellows construction offers built-in height compensation and stroke flexibility. This design allows the suction cup to adapt to irregular shapes while maintaining a secure seal, even if the workpiece surface is not completely flat.
This product range includes seven different diameters, spanning from 15 mm up to 125 mm. Customers can choose from three distinct material options tailored to meet various workpiece needs. NBR (nitrile rubber) serves as the universal choice for general industrial applications, known for its excellent resistance to wear and oil. It is available in two colors: black as the standard and blue for cases requiring visual differentiation. On the other hand, silicone (SI) is offered in white and is ideal for applications demanding high temperature resistance and suitability for the food industry. Its soft surface contact also helps minimize marking on delicate surfaces.
Each suction cup is equipped with a fixed threaded connection for straightforward installation. The thread sizes vary according to the suction cup diameter: G1/8 for sizes between 15 and 30 mm, G1/4 for 40 to 100 mm, and G3/8 for the 125 mm variant. This feature enables direct mounting onto vacuum generators, grippers, or handling systems without the need for additional adapters. Holding forces range from 7.9 N for the 15 mm NBR suction cup, up to an impressive 610 N for the 125 mm silicone model, covering a broad spectrum of applications from light assembly to handling heavy workpieces. Additionally, these suction cups comply with RoHS standards and function using atmospheric air according to ISO 8573-1:2010.
Features:
The bellows feature a 1.5-fold design, which allows for height compensation and adaptability to uneven, curved, or inclined workpieces, ensuring reliable gripping in various applications.
Available in seven different diameters ranging from 15 mm to 125 mm, these bellows cover a wide spectrum of uses, from light assembly tasks to heavy material handling operations.
There are three material and color options to choose from: black NBR for general industrial applications, blue NBR for easy visual differentiation, and white silicone designed specifically for high-temperature environments and food industry applications.
These bellows deliver high holding forces, with values spanning from 7.9 N for the 15 mm black NBR version up to 610 N for the 125 mm silicone variant, all measured at nominal operating pressure.
Fixed threaded connections are available in sizes G1/8, G1/4, or G3/8 depending on the bellows size, enabling direct mounting without the need for adapters.
The materials used have specific temperature ranges: NBR operates between -20°C and +80°C, PUR between -20°C and +60°C, and silicone from -40°C up to +200°C, catering to diverse operating environments.
Silicone versions are particularly suitable for the food industry, as they are approved for food-contact applications and exhibit excellent resistance to high temperatures.
With a corrosion resistance class of CRC 2, these bellows offer moderate tolerance to corrosion, making them ideal for various industrial settings.
They are RoHS compliant, ensuring an environmentally friendly construction, and conform to LABS (PWIS) standards, which means they are suitable for paint-wetting impairment-sensitive applications.
Overall, the bellows boast a robust and reliable construction, engineered to meet the demands of industrial vacuum handling with consistent performance.

Applications:
The bellows design offers enhanced adaptability for handling uneven, curved, or inclined workpieces. This flexible structure provides the necessary compliance in situations where traditional flat cups are unable to form a proper seal.
In the realm of flexible automation, these solutions support a wide range of operations including lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning of various components with efficiency and precision.
When it comes to packaging, the products excel at gripping cartons, films, and packaged goods that have irregular surfaces, ensuring secure handling without damage.
The electronics and precision assembly sectors benefit from specialized handling of printed circuit boards (PCBs), small components, and delicate housings. Silicone versions are available for applications requiring particularly sensitive surface contact to prevent damage.
For the food and beverage industry, silicone cups meet strict approval standards and are fully suitable for use in high-temperature processing environments, providing both safety and reliability.
In automotive manufacturing, these solutions facilitate the handling of body panels, glass parts, and other components featuring curved geometries, ensuring effective manipulation without compromising the integrity of the materials.
Battery production benefits from versions made from NBR and PUR materials, available in sizes ranging from 8 to 55 mm. Additionally, F1A-grade materials are offered specifically to meet the stringent requirements of lithium-ion battery manufacturing systems.
