Product Description:
The VAS series consists of industrial vacuum suction cups specifically engineered for dependable gripping, lifting, and handling of workpieces within both automated and semi-automated production environments. These suction cups come in a variety of seven diameters, ranging from 15 mm to 125 mm, enabling accommodation of a broad spectrum of workpiece sizes and weights. Each suction cup is equipped with a fixed threaded connection—either G1/8, G1/4, or G3/8 depending on the size—allowing for direct attachment to vacuum generators, grippers, and various handling systems.
To cater to different surface types and environmental conditions, three distinct suction cup materials are available. NBR (nitrile rubber) serves as a versatile option suitable for general industrial applications, as it offers excellent resistance against oils, abrasion, and wear. PUR (polyurethane) is chosen for its extended durability and its gentle handling of sensitive surfaces, attributed to its softer material composition. Additionally, Silicone (SI) is designed for high temperature resistance, making it an ideal choice for applications in the food industry and other environments that require elevated temperature tolerance.
The VAS series also offers two suction cup shapes to meet specific application needs. The round flat design (VAS) is optimized for smooth, flat workpieces that have a good surface finish. In contrast, the protective bellows shape (VASB) provides compensation for height variations and excels in handling uneven, curved, or textured surfaces where extra flexibility and shock absorption are necessary. These suction cups comply with RoHS standards and operate using atmospheric air in accordance with ISO 8573-1:2010 guidelines.
Typical applications of the VAS suction cups include a wide range of handling tasks such as lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning components within flexible automation systems. This versatility makes them an essential component in modern industrial automation processes.
Features:
Our product range offers seven diameter options, ranging from 15 mm to 125 mm, effectively accommodating a wide variety of workpiece sizes and weight requirements. This flexibility ensures compatibility with numerous industrial applications.
There are three different material choices available to suit specific needs: NBR, ideal for universal industrial use; PUR, which provides a long service life alongside gentle handling characteristics; and silicone, designed for high-temperature environments and food industry applications.
When it comes to suction cup shapes, we provide two distinct designs. The round flat (VAS) suction cups are perfect for smooth surfaces, while the protective bellows (VASB) are engineered for uneven or curved surfaces, offering height compensation to maintain optimal contact.
The product features fixed threaded connections, available in G1/8, G1/4, or G3/8 sizes depending on the diameter chosen. This design allows for direct mounting without the need for additional adapters, simplifying installation and increasing stability.
Constructed with durability and reliability in mind, these suction cups are built to meet the demands of rigorous industrial gripping and handling tasks. Their robust design ensures consistent performance even in challenging environments.
Material properties include NBR with a Shore hardness of 70 ± 5, providing a balanced combination of flexibility and wear resistance suitable for general-purpose gripping. PUR features a softer Shore hardness of 60 ± 5, allowing for gentle treatment of sensitive workpieces. Silicone exhibits a Shore hardness of 55 ± 5, offering softness along with high-temperature resistance tailored for food-grade and heat-exposed uses.
Compliance with LABS (PWIS) standards is ensured, meeting the VDMA24364-A1-L guideline, which makes these suction cups suitable for paint-wetting impairment-sensitive applications. They also possess corrosion resistance class CRC 2, indicating moderate tolerance to corrosion in industrial settings.
Environmentally, the goods are RoHS compliant, reflecting an eco-friendly construction process. Regarding operating parameters, the temperature range spans from -20°C to +80°C for standard NBR versions, with silicone variants capable of handling extended temperatures. The nominal operating pressure is optimized at -0.7 bar, providing efficient vacuum generation and reliable holding force.

Applications:
Flexible automation encompasses a variety of functions including lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning of different components. This versatility allows for efficient handling and manipulation across many industrial applications.
In material handling, systems such as pick-and-place robots, specialized robot end-effectors, and automated transfer lines are widely used. These technologies streamline the process of moving components, improving speed and accuracy in manufacturing environments.
Packaging machinery benefits from advanced gripping mechanisms designed for the precise handling and placement of cartons, films, and packaged goods. These innovations help ensure packaging quality and reduce product damage during processing.
The electronic component manufacturing sector relies on delicate handling techniques for printed circuit boards (PCBs), small parts, and sensitive assemblies. Specialized equipment ensures these components are managed carefully to maintain their integrity.
Food and beverage processing requires materials that meet stringent hygiene and safety standards. Silicone variants are particularly suitable for food-contact applications and can withstand high temperatures, making them ideal for this industry.
Automotive manufacturing involves the handling of large and heavy components such as body panels, glass, and various assembly line parts. Flexible automation solutions contribute to efficient and precise assembly processes.
General industrial gripping applications demand reliable vacuum gripping technology to manage flat or uneven workpieces effectively. This capability supports a wide range of manufacturing and processing tasks across different sectors.
