Product Description:
The VASB series consists of bellows-type vacuum suction cups designed to provide reliable gripping and handling of workpieces that feature uneven, curved, or inclined surfaces. Unlike traditional flat suction cups, the unique 1.5-fold bellows design integrates height compensation and stroke capability, allowing the cup to adapt to irregular shapes while maintaining a secure seal even when the surface of the workpiece is not completely flat.
This product range includes seven different diameters, spanning from 15 mm up to 125 mm. There are three material options available to suit various workpiece needs. NBR (nitrile rubber) is the universal choice for general industrial applications, known for its excellent wear resistance and oil resistance. It comes in black as the standard color, with an additional blue version intended for applications where visual differentiation is required. Silicone (SI), offered in white, provides high temperature resistance and is suitable for the food industry. Its soft contact surface helps minimize marking on sensitive materials.
Each suction cup is equipped with a fixed threaded connection for straightforward installation—G1/8 for sizes 15 to 30 mm, G1/4 for sizes 40 to 100 mm, and G3/8 for the 125 mm cup. This enables direct mounting to vacuum generators, grippers, and handling systems without the need for adapters. The holding forces vary significantly, ranging from 7.9 N for the smallest 15 mm NBR cup to as much as 610 N for the largest 125 mm silicone cup, covering a wide spectrum of applications from light assembly to heavy workpiece manipulation.
Furthermore, all VASB suction cups comply with RoHS standards and operate by using atmospheric air in accordance with ISO 8573-1:2010 guidelines, ensuring both environmental safety and reliable performance.
Features:
The bellows feature a 1.5-fold design, which allows for height compensation and adapts seamlessly to uneven, curved, and inclined workpieces. This ensures a reliable grip in various handling scenarios.
Available in seven diameters ranging from 15 mm to 125 mm, these components are suitable for a wide spectrum of applications, from light assembly tasks to heavy material handling operations.
There are three material and color options to choose from: black NBR for general industrial purposes, blue NBR for easy visual differentiation, and white silicone designed specifically for high-temperature environments and food-industry requirements.
These products deliver high holding forces, varying from 7.9 N for the 15 mm NBR variant up to 610 N for the 125 mm silicone model, all measured at nominal operating pressure.
Fixed threaded connections are provided in different sizes—G1/8, G1/4, or G3/8—depending on the particular model. This allows for direct mounting without the need for adapters.
Each material type supports specific temperature ranges: NBR operates between -20°C and +80°C; PUR is effective from -20°C to +60°C; and Silicone withstands temperatures from -40°C up to +200°C.
The silicone options are especially suitable for the food industry, as they are approved for food contact and demonstrate resistance to high temperatures.
Featuring corrosion resistance class CRC 2, these grippers can tolerate moderate corrosion stress, making them reliable components for demanding industrial environments.
The design complies with RoHS standards, ensuring environmentally friendly construction practices.
Additionally, the products meet LABS (Paint-Wetting Impairment Substances) conformity, which makes them appropriate for applications sensitive to paint-wetting impairments.
Built with robustness and reliability in mind, these vacuum handling components are engineered to perform effectively under challenging industrial conditions.

Applications:
The handling of uneven, curved, or inclined workpieces is made possible through the bellows design, which offers flexibility and compliance in applications where traditional flat cups fail to create an adequate seal.
Flexible automation encompasses a wide range of tasks including lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning of various components. These capabilities enable efficient and versatile operations in automated systems.
In the packaging industry, gripping cartons, films, and packaged goods with irregular surfaces is a common challenge. The use of specially designed cups allows for secure handling of such items despite their uneven contours.
Electronics and precision assembly processes benefit from specialized handling of printed circuit boards (PCBs), small parts, and delicate housings. Silicone versions of the cups are available to accommodate sensitive surfaces without causing damage.
For food and beverage processing, silicone cups meet industry standards for food safety and are suitable for applications involving high temperatures, ensuring hygiene and durability in demanding environments.
In the automotive manufacturing sector, these handling solutions are ideal for managing body panels, glass components, and other parts with complex curved geometries, enhancing efficiency and product integrity.
Battery production, particularly for lithium-ion batteries, utilizes materials such as NBR and PUR in sizes ranging from 8 to 55 mm. Versions compliant with the F1A specification are available, supporting high standards required in advanced battery manufacturing systems.

Product Technical Support and Services for Vacuum Suction Cup
Our Vacuum Suction Cups are designed to provide reliable and efficient handling solutions for a variety of applications. To ensure optimal performance and longevity, please follow the guidelines below:
Installation and Usage:
Before installation, inspect the suction cup for any damage or debris. Clean the surface where the suction cup will be applied to ensure a secure seal. Avoid using the suction cup on rough, porous, or uneven surfaces as this may reduce holding strength.
Maintenance:
Regularly clean the suction cup with mild soap and water to remove dirt and contaminants. Avoid using harsh chemicals or abrasive materials which can degrade the cup material. Inspect periodically for signs of wear or damage and replace if necessary.
Troubleshooting:
If the suction cup fails to hold properly, check for surface cleanliness, ensure the vacuum source is functioning correctly, and verify that the cup is compatible with the material being handled. Adjust positioning and pressure to improve grip.
