Product Description:
The VASB series consists of bellows-type vacuum suction cups designed to provide reliable gripping and handling for workpieces with uneven, curved, or inclined surfaces. Unlike traditional flat suction cups, the unique 1.5-fold bellows construction offers built-in height compensation and stroke capabilities. This design enables the suction cups to adapt to irregular shapes, ensuring a secure seal even when the surface of the workpiece is not perfectly flat.
The series includes seven different diameters ranging from 15 mm to 125 mm, accompanied by three material variants tailored to various application needs. NBR (nitrile rubber) is widely used across general industrial applications due to its excellent wear and oil resistance. It is offered in black as the standard option, with a blue variant available for situations requiring visual differentiation. Additionally, silicone (SI) suction cups come in white and are known for their high temperature resistance and suitability for the food industry. The soft silicone contact surface helps minimize marking on delicate workpieces.
Each suction cup in the VASB series is equipped with a fixed threaded connection to facilitate straightforward mounting. The thread sizes are G1/8 for suction cups sized 15 to 30 mm, G1/4 for sizes 40 to 100 mm, and G3/8 for the 125 mm diameter cups. This allows direct attachment to vacuum generators, grippers, and handling systems without the need for additional adapters. The holding force varies significantly, starting from 7.9 N for the smallest 15 mm NBR cup up to a maximum of 610 N for the largest 125 mm silicone cup, making the series versatile for tasks ranging from light assembly to heavy-duty handling.
Furthermore, the VASB suction cups comply with RoHS standards and operate using atmospheric air in accordance with ISO 8573-1:2010. This ensures both environmental compliance and dependable performance in diverse industrial environments.
Features:
The bellows feature a 1.5-fold design that allows for effective height compensation. This design also adapts well to uneven, curved, and inclined workpieces, ensuring reliable gripping in various applications.
Available in seven different diameters ranging from 15 mm up to 125 mm, these bellows cater to a wide range of tasks, from light assembly operations to heavy material handling needs.
There are three material and color options to choose from: black NBR, which is suitable for universal industrial use; blue NBR, designed for visual differentiation; and white silicone, ideal for high-temperature environments and food industry applications.
The bellows provide high holding forces, with values ranging from 7.9 N for the 15 mm NBR model to as much as 610 N for the 125 mm silicone variant, all measured at nominal operating pressure.
Fixed threaded connections are available in G1/8, G1/4, or G3/8 sizes depending on the bellows dimension, allowing for direct mounting without the need for adapters.
The materials used offer specific temperature ranges: NBR can withstand temperatures from -20°C to +80°C, PUR from -20°C to +60°C, and silicone from -40°C up to +200°C, providing versatility for different operating environments.
Specifically, the silicone versions are suitable for food industry use, being approved for food-contact applications and resistant to high temperatures, ensuring compliance with hygiene standards.
These bellows have a corrosion resistance class (CRC) of 2, which indicates moderate tolerance to corrosion stresses commonly found in industrial environments.
Environmentally, the product is RoHS compliant, guaranteeing an eco-friendly construction. Additionally, it conforms to LABS (PWIS) standards, making it suitable for applications sensitive to paint-wetting impairment substances.
Overall, the robust and reliable construction of these bellows makes them well-suited for demanding industrial vacuum handling tasks, ensuring long-lasting performance and operational safety.

Applications:
When dealing with uneven, curved, or inclined workpieces, traditional flat cups often fail to create a proper seal. In such cases, bellows design offers the necessary compliance, ensuring a secure grip and effective handling even on irregular surfaces.
Flexible automation encompasses a wide range of tasks including lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning of components. This versatility enhances productivity across various industries.
In the packaging sector, specialized gripping solutions handle cartons, films, and packaged goods that have irregular surfaces. This capability is crucial for maintaining product integrity during processing and transit.
The electronics and precision assembly fields benefit from handling delicate items such as printed circuit boards (PCBs), small parts, and fragile housings. Silicone versions are available to accommodate sensitive surfaces without causing damage.
Food and beverage processing requires hygienic and durable materials. Silicone cups comply with food-industry regulations and are suitable for applications involving high temperatures, making them ideal for this sector.
Automotive manufacturing involves the handling of body panels, glass components, and parts with complex curved geometries. Advanced gripping solutions ensure secure and gentle handling throughout the production process.
For battery production, particularly lithium-ion battery manufacturing systems, NBR and PUR versions are available in sizes ranging from 8 to 55 mm, meeting the F1A material specification. This ensures compliance with industry standards and optimal performance.
