Extra Compliance for Irregular Packaging and Product Surfaces
Multiple-bellows vacuum suction cups provide greater vertical travel and flexibility than single-bellows designs. They can compress substantially during product contact, helping the cup adapt to uneven packages, variable heights and less predictable surface geometry.
The source range is particularly suited to food packaging and is available in NBR, silicone, FDA-compliant silicone and metal-detectable silicone, with listed diameters from 20 mm to 90 mm.

- Diameters from 20 mm to 90 mm
- NBR rubber options
- Silicone rubber options
- FDA-compliant silicone options
- Metal-detectable silicone options
- High compliance for uneven product surfaces
Why Choose Multiple Bellows?
- The additional bellows travel allows the cup to adapt to larger product-height differences and more irregular packaging than a flatter cup design.
- This makes multiple-bellows cups especially useful when packages deform or when the product surface is not consistently flat.
Common Applications
- Food packaging
- Bags and flexible packages
- Cartons and containers
- Packaging machinery
- Robotic pick-and-place
- Product sorting and transfer
Frequently Asked Questions
What is a multiple-bellows vacuum cup?
It is a suction cup with several flexible bellows sections that provide increased vertical compliance.
Why are multiple bellows useful for packaging?
They can deform to follow uneven or variable-height product surfaces, which helps when handling flexible or irregular packages.
What diameter range is listed?
The source range lists diameters from 20 mm to 90 mm.
What materials are available?
The source range includes NBR, silicone, FDA-compliant silicone and metal-detectable silicone.
Are multiple-bellows cups suitable for food packaging?
Yes. Food packaging is specifically identified as a key application in the source description.
What is the difference between single and multiple bellows?
Multiple bellows generally provide more vertical travel and flexibility, while single bellows provide a smaller amount of compliance.
Can they compensate for product-height variation?
Yes. Their compressible design is intended to accommodate variation in product height and approach position.
How do I select the right cup?
Consider product weight, package flexibility, surface shape, cup size, material, vacuum level and machine acceleration.
