Technical Overview

The Festo VASB-55-1/4-PUR-B is a high-performance suction cup complete assembly designed for vacuum-based handling systems. It features a round bellows shape with 1.5 convolutions, enabling a 20mm height compensation for irregular workpieces. Constructed with a durable Polyurethane (PUR) suction cup and a robust die-cast zinc screwed plug, this unit is engineered for moderate corrosion stress (CRC 2) and operates within a wide temperature range from -20 to 60 °C. It provides a significant holding force of 110 N at nominal operating pressure and connects via a G1/4 vacuum port.

Industrial Applications

1. Automotive Painted Panel Handling

End-of-arm tooling (EOAT) on robotic arms lifting and moving curved automotive body panels before the painting process. The polyurethane construction offers high wear resistance, while the bellows design accommodates panel curvatures.

Problem Solved

Prevents surface contamination and adapts to curved, uneven automotive panels without losing vacuum seal. The LABS (PWIS) conformity VDMA24364-A1-L ensures no paint-wetting impairment substances are left on the panels, while the 20mm height compensation manages the curved geometries of stamped parts. A holding force of 110 N securely lifts the metal sheets.

2. End-of-Line Cardboard Carton Palletizing

Automated palletizing system gripping porous and slightly uneven corrugated cardboard boxes. The suction cup utilizes its 55mm diameter and 1.5 convolutions to conform to carton surfaces that might be sagging or unevenly taped.

Problem Solved

Corrugated cardboard often has irregular heights and abrasive surfaces. The 20 mm height compensator allows the vacuum cup to securely grasp cartons with varying dimensions, while the tough PUR material with 60 +/- 5 Shore hardness resists the highly abrasive nature of cardboard, extending maintenance intervals.

3. Warm Injection-Molded Plastic Part Extraction

Robotic extraction system safely removing newly formed, delicate plastic enclosures from an injection molding machine using the 1.5 convolution bellows for a gentle touch.

Problem Solved

Freshly molded plastic parts are often warm, fragile, and not perfectly flat. The -20 C to 60 C ambient temperature rating safely handles warm parts. The 1.5 convolutions act as a cushion during initial contact to avoid stressing the fragile plastic, and the -0.7 bar nominal operating pressure ensures reliable extraction without deforming the component.
