Festo 40 mm Bellow Nitrile Rubber (NBR) Suction Cup ESS-40-BN M6

This suction cup is a vacuum handling pad designed for pick-and-place and material handling in automated systems. It uses a flexible bellows pad to conform to irregular surfaces and connects via an M6 threaded Interface positioned on the TOP for vacuum entry. The pad is MADE from nitrile rubber suitable for general industrial environments and is intended for integration where precise, repeatable grip is required.

• M6 threaded connection enables simple integration with actuators
• Bellows-style pad accommodates uneven surfaces for secure grip
• Nitrile rubber composition resists common oils and greases
• 52.3N holding force supports reliable component transfer
• RoHS compliance aligns with restricted-substance requirements

• Suitable for automated pick-and-place of electronic components
• Ideal for end-of-arm tooling on robotic manipulators
• Used for handling small electrical assemblies during production
• Can be used for mechanical parts transfer in assembly lines

The vacuum is introduced through the top-mounted M6 connection, allowing direct pipe or fitting attachment for pneumatic supply.

The bellows geometry combined with nitrile rubber delivers elastic conformity to mildly irregular surfaces while maintaining vacuum seal integrity.

Use an M6 threaded Interface adaptor or fitting to secure the pad to standard threaded ports on end-of-arm tooling.

Design calculations should use the 52.3N holding capability as the steady-state grip Value for component retention under vacuum.
