GIMATIC VG.GX Multi-Bellows Polyurethane Suction Cups Review: Specs, Price and Applications
The GIMATIC VG.GX series consists of multi-bellows polyurethane suction cups designed to compensate for height differences and to handle items with porous and uneven surfaces.
The polyurethane material offers exceptional elastic memory. Cups are available in 50 Shore hardness (green) or as a two-colour 30/60 Shore version that combines a soft sealing lip with a robust body.
Quick Verdict
A strong choice for bags, cartons and irregular products where a flat cup cannot seal. The dual-hardness version balances sealing and stability.

Design and Operating Principle
Each bellows fold acts as a spring, so a multi-bellows cup can compress significantly to absorb differences in product height and adapt to tilted surfaces. When vacuum builds, the bellows contract and lift the part slightly, which helps separate stacked items.
Polyurethane is more wear-resistant than many rubbers and keeps its shape after repeated compression, which is what elastic memory refers to. That extends cup life on abrasive cardboard and plastic films.
The two-colour 30/60 Shore design uses a soft lip to seal on rough or flexible surfaces while the harder body resists collapsing under load, improving lateral stability during fast moves.
Integration and Selection
Choose cup size and count from part weight, acceleration and surface porosity; porous products need a vacuum generator with enough flow. Use the 30/60 version where sealing is difficult.
Allow for bellows compression in the robot approach height so the cups contact the product consistently.
