Festo VASB-30-1/8-SI-B 1377637 1.5-Fold Bellows Suction Cup

Festo VASB-30-1/8-SI-B is a round, 30 mm diameter bellows suction cup designed for handling workpieces in industrial automation. Its 1.5‑fold bellows structure allows for height compensation and gentle, flexible adaptation to uneven or curved surfaces. Made from transparent VMQ (silicone) for high‑temperature resistance and compliance with food‑industry regulations. The G 1/8 connection thread enables direct attachment to Festo vacuum components.

Applications:

• Packaging and printing machinery

• Robotic pick‑and‑place, material handling

• Handling uneven, curved, or sensitive workpieces

• Food and high‑temperature environments (silicone construction)
