Festo 50 mm Bellow Silicone Suction Cup ESS-50-BS M6

This suction cup is a pneumatic handling component designed for automated pick-and-place tasks in industrial settings. It uses a flexible silicone pad formed as a bellows to conform to uneven or curved surfaces while connecting to vacuum systems via an M6 Interface with vacuum entry on top. The component is suitable for integration into machinery where controlled gripping and release of parts is required.

• 72.6N holding force enables secure part retention during transfer • Silicone bellows pad improves surface conformity for irregular items • RoHS-compliant construction minimises restricted-substance concerns • M6 connection offers compact, standardised fitting for actuators • Top-entry vacuum reduces interference with tooling and workpieces

• Suitable for automated pick-and-place of delicate electronic components • Ideal for handling small mechanical parts on assembly lines • Used with robotic end-effectors for board-level component placement • Can be used for temporary holding during electrical testing procedures

The elastomeric bellows profile increases contact area and flexibility, allowing reliable sealing on slightly curved or textured surfaces where rigid pads would lose grip.

With vacuum introduced from the top, piping and hoses can be routed away from the workpiece, simplifying end-effector design and reducing the risk of collision.

The M6 threaded Interface permits direct mounting to standard fittings and adaptors, enabling Compact assembly on cylinders, grippers, or vacuum manifolds.

The silicone pad provides chemical and temperature tolerance typical of silicone elastomers, which helps maintain compliance and grip across a range of handling conditions.
