Product Description:
The VAS series consists of industrial vacuum suction cups engineered to provide reliable gripping, lifting, and handling of workpieces in both automated and semi-automated production environments. These suction cups come in a variety of seven diameters, ranging from 15 mm to 125 mm, allowing them to accommodate a broad spectrum of workpiece sizes and weights. Each suction cup is equipped with a fixed threaded connection—options include G1/8, G1/4, or G3/8 depending on the size—enabling direct attachment to vacuum generators, grippers, and handling systems.
To meet the diverse needs of different workpiece surfaces and environmental conditions, three distinct materials are available for the suction cups. NBR (nitrile rubber) is the standard choice for most industrial applications due to its excellent resistance to oils, abrasion, and general wear. PUR (polyurethane) is designed for longer durability and offers a softer composition, making it ideal for gently handling sensitive surfaces. Silicone (SI), known for its high temperature resistance, is particularly suited for applications in the food industry and other settings where elevated temperature tolerance is required.
The suction cups come in two different shapes to suit varying surface textures and shapes. The round flat design, known as VAS, is best suited for smooth, flat workpieces that have a refined surface finish. On the other hand, the protective bellows design, referred to as VASB, offers height compensation and flexibility. This shape is perfect for handling uneven, curved, or textured surfaces where additional shock absorption and adaptability are necessary.
Compliant with RoHS standards, the VAS series suction cups operate using atmospheric air based on the ISO 8573-1:2010 standard. They are widely applied in numerous industrial tasks such as lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning components. These capabilities make them integral components in flexible automation systems.
Features:
Versatile Diameter Options
The product is available in seven different diameters, ranging from 15 mm up to 125 mm. This wide range ensures compatibility with various workpiece sizes and weight requirements, making it suitable for diverse industrial applications.
Material Choices for Different Needs
There are three material options to choose from: NBR, PUR, and silicone. NBR is ideal for universal industrial use, offering a good balance of flexibility and durability. PUR is designed for long service life and provides gentle handling of sensitive workpieces. Silicone is tailored for high-temperature environments and food-industry applications, ensuring safety and compliance.
Two Suction Cup Designs
Users can select between two suction cup shapes to best suit their surface conditions. The round flat cup (VAS) works effectively on smooth surfaces, while the protective bellows design (VASB) is excellent for uneven or curved surfaces, thanks to its height compensation capability.
Reliable and Easy Mounting
Fixed threaded connections are available in sizes G1/8, G1/4, or G3/8, depending on the suction cup diameter. This design allows for direct mounting without the need for additional adapters, simplifying installation.
Robust Construction for Industrial Use
Built with sturdy and reliable materials, these suction cups are engineered to handle demanding industrial gripping and handling tasks with consistent performance and durability.
Material Hardness Specifications
- NBR: Shore hardness 70 ± 5, providing a good balance of flexibility and wear resistance for general-purpose gripping.
- PUR: Shore hardness 60 ± 5, a softer material designed for gentle treatment of sensitive workpieces.
- Silicone: Shore hardness 55 ± 5, offers softness and high-temperature resistance, suitable for food and heat-exposed applications.
Compliance and Environmental Standards
The products conform to LABS (PWIS) standards, specifically VDMA24364-A1-L, making them suitable for applications sensitive to paint-wetting impairments. They are classified under corrosion resistance class CRC 2, indicating moderate tolerance to corrosion in industrial environments. Additionally, all variants are RoHS compliant, reflecting an environmentally friendly design.
Operating Conditions
The standard NBR versions operate efficiently within a temperature range of -20°C to +80°C. Silicone versions extend this capability further for use in higher temperature environments. The nominal operating pressure is optimized at -0.7 bar, delivering effective vacuum generation and strong holding force.

Applications:
Flexible automation involves a variety of tasks such as lifting, equipping, moving, inserting, conveying, gripping, holding, stacking, clamping, transporting, repositioning, and turning components. These processes require adaptable solutions to handle different shapes and sizes efficiently.
In material handling, systems like pick-and-place robots, end-effectors for robots, and automated transfer lines play a crucial role. These technologies enable precise and reliable movement and positioning of items within manufacturing and processing environments.
Packaging machinery benefits from advanced gripping and placement techniques designed for cartons, films, and packaged goods. These methods ensure accurate handling and protection of products during packaging operations.
The electronic component manufacturing sector relies on specialized handling of printed circuit boards (PCBs), small parts, and delicate assemblies. Careful manipulation is essential to maintain quality and functionality throughout the production process.
In food and beverage processing, silicone variants are used that are suitable for food-contact applications as well as environments involving high temperatures. These materials ensure safety and compliance with industry standards.
Automotive manufacturing requires handling of various elements such as body panels, glass, and other components on assembly lines. Efficient vacuum gripping solutions contribute to streamlined production and reduced downtime.
General industrial gripping covers any application that demands dependable vacuum gripping of both flat and uneven workpieces. This versatility makes vacuum technology an essential tool across numerous industrial sectors.
