Nobody likes wrinkles! But they are very desirable on these suction cups. They compensate for deviations in height, and provide good adaptation. The part is suctioned with stroke "Z". This can make one additional stroke cylinder obsolete.
The bellowed suction cups are available in oil-resistant Perbunan (NBR, black), temperature-resistant food safe Silicone (up to +200 °C, white-transparent), or a natural rubber (grey) with a soft consistency like 45 Shore, especially suitable for uneven problematic surfaces.
The suction cups can be pushed onto the adapters or vacuum ejectors very easily.

The blue model HT (high temperature material) leaves no imprints and is especially suitable for plastics, oily surfaces, and porous materials like stone and wood.

For information about the technical features refer to our material overview. Matching suction lifting cylinders are available here.
