Product Description:
The VAS series consists of industrial vacuum suction cups that are engineered to provide reliable gripping, lifting, and handling of workpieces within both automated and semi-automated production environments. These suction cups are available in seven different diameters, ranging from 15 mm to 125 mm, accommodating 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—for direct attachment to vacuum generators, grippers, and various handling systems.
To adapt to diverse workpiece surfaces and environmental conditions, the VAS series offers three distinct suction cup materials. NBR (nitrile rubber) serves as a versatile option ideal for general industrial use, delivering excellent resistance to oils, abrasion, and wear. PUR (polyurethane) is characterized by its softer texture, which not only extends the service life but also ensures gentle handling of delicate surfaces. Silicone (SI) suction cups stand out with their high-temperature resistance, making them especially suitable for food industry applications and other scenarios that demand elevated temperature tolerance.
The series features two suction cup designs. The round flat shape, referred to as VAS, is perfect for smooth, flat workpieces that have a well-finished surface. Alternatively, the protective bellows shape, known as VASB, offers height compensation and is tailored for uneven, curved, or textured surfaces where enhanced flexibility and shock absorption are necessary. Additionally, all suction cups comply with RoHS standards and operate using atmospheric air in accordance with ISO 8573-1:2010.
Typical uses of the VAS series 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. Their versatility and reliability make them an essential component in modern industrial production.

Vacuum Suction Cup Features and Specifications
The product offers seven different diameter options ranging from 15 mm to 125 mm. This extensive variety ensures compatibility with a broad spectrum of workpiece sizes and weight requirements, making it versatile for numerous industrial applications.
Customers can choose from three types of materials tailored to specific needs: NBR, which is suitable for universal industrial use; PUR, designed for long service life and gentle handling of workpieces; and silicone, ideal for applications involving high temperatures and the food industry.
Two distinct suction cup shapes are available. The round flat design (VAS) works best on smooth surfaces, while the protective bellows model (VASB) is intended for uneven or curved surfaces, providing height compensation to ensure a secure grip.
The suction cups come with fixed threaded connections in various sizes—G1/8, G1/4, or G3/8—depending on the diameter. This allows for direct mounting without the need for adapters, simplifying installation and improving reliability.
Built with sturdy and reliable construction, these suction cups are engineered to withstand demanding industrial gripping and handling tasks, offering durability and consistent performance over time.
Material Hardness and Properties
The NBR material has a Shore hardness of 70 ± 5, striking a good balance between flexibility and wear resistance, making it suitable for general-purpose gripping applications.
PUR material features a Shore hardness of 60 ± 5, which is softer and provides gentle treatment for sensitive or delicate workpieces.
Silicone material comes with a Shore hardness of 55 ± 5, offering a soft yet highly temperature-resistant solution especially suited for food-related or heat-exposed environments.
Compliance and Environmental Considerations
These suction cups comply with LABS (PWIS) standards under VDMA24364-A1-L, ensuring suitability for applications sensitive to paint-wetting impairments.
With a corrosion resistance classification of CRC 2, the design tolerates moderate corrosion stress, making it appropriate for various industrial environments.
Furthermore, the products are RoHS compliant, reflecting their environmentally friendly construction and adherence to hazardous substance restrictions.
Operating Conditions
The standard NBR suction cups operate efficiently within a temperature range of -20°C to +80°C. Silicone versions extend this capability, permitting usage in higher temperature scenarios.
The nominal operating pressure is set at -0.7 bar, optimizing the balance between vacuum generation and holding force, ensuring effective gripping performance.
