Piab DURAFLEX XP Single Bellow Suction Cups Review: Specs, Price and Applications

The Piab DURAFLEX XP single bellow suction cups come in diameters from 10 to 110 mm and use a dual-durometer construction: a firm bellows combined with soft, flexible lips that blend rubber's elasticity with polyurethane's wear resistance.
They are well suited to uneven and porous surfaces, leave no marks and contain no Paint Wetting Impairment Substances (PWIS). Compared with multi-bellows cups, they have a lower building height and higher lifting force per cup, and stay stable at higher robot speeds.
Quick Verdict
A versatile everyday cup that combines low height, high force and stability, ideal for fast injection molding take-out and precise placement.

Design and Operating Principle
A single bellow gives some height compensation while keeping the cup short and stiff. That stiffness means the part does not swing during fast moves, so the robot can accelerate harder and still place parts accurately in fixtures.
Higher lifting force per cup means fewer cups may be needed, which lowers initial cost, simplifies the tool and reduces weight.
PWIS-free material is essential in automotive paint shops and for parts that will be painted later, because silicone and similar substances cause paint defects. Good sealing reduces leakage, allowing smaller vacuum pumps and lower energy costs.
Integration and Selection
Select diameter from part weight and acceleration, and use the lower height in tight spaces such as inside molds. Size the vacuum generator for the reduced leakage.
Check the cup fittings against the gripper's mounting system.
