Festo VASB-30-1/8-SI-B Vacuum Suction Cup 30mm 25N 1/8" G Silicone

Overview
The Festo VASB-30-1/8-SI-B (part number 1377637) is a high-performance 1.5‑bellows suction cup from the VASB series, designed for reliable gripping of workpieces with uneven, curved, or smooth surfaces in automated handling applications. Featuring a 30 mm suction diameter and a transparent VMQ (silicone) pad, this cup delivers excellent flexibility, temperature resistance, and sealing performance. The 1.5‑bellows design provides height compensation up to 13.9 mm, making it ideal for pick‑and‑place, packaging, and robotic handling tasks where workpiece height varies.

The suction cup is fitted with a male G1/8 thread for direct connection to standard vacuum systems and supports a wide operating pressure range from 0 to 0.95 bar (vacuum operation down to –0.95 bar). With a holding force of 25 N at nominal operating pressure and a low suction cup volume of just 6.18 cm³, the VASB-30-1/8-SI-B ensures rapid evacuation and short cycle times. The silicone material offers a Shore hardness of 60 ± 5, providing an optimal balance between grip and adaptability, while the transparent colour allows visual inspection of workpiece contact.

The cup operates reliably over an extreme temperature range of –40 °C to +200 °C, making it suitable for applications in hot or cold environments, including food processing, glass handling, and electronics assembly. The connection is positioned on top of the cup, enabling easy integration into existing vacuum tooling. The VASB-30-1/8-SI-B is RoHS compliant and manufactured in Germany to Festo‘s renowned quality standards.

Key Features

Technical Specifications

Applications
Ideal for automated pick‑and‑place systems, packaging machinery, material handling, food processing (dry goods, baked items), glass and electronics handling, injection moulding part extraction, and robotic gripper systems. The 1.5‑bellows design and silicone material make it particularly suitable for gripping slightly curved, fragile, or high‑temperature workpieces where surface contact needs to be gentle yet secure.
