Single-Bellows Cups for Fast, Compliant Product Pickup
Single-bellows vacuum suction cups provide a moderate amount of vertical compliance while maintaining a compact cup profile. They are commonly used where a product needs gentle contact or where small height variations must be absorbed during pickup.
The source range includes silicone, NBR, nitrile rubber and FDA-compliant metal-detectable rubber options. Typical uses include paper and carton handling as well as extraction of molded products from injection-molding equipment.

- Compact single-bellows design
- Helps absorb small product-height variations
- Suitable for paper and carton handling
- Useful for molded-part extraction
- Multiple elastomer material options
- FDA-compliant metal-detectable options available in the range
Why Use a Single Bellows?
- A single bellows provides more compliance than a flat cup while remaining relatively stable during lateral machine movement.
- This makes the design a practical choice for many packaging, automation and molded-part handling tasks.
Common Applications
- Paper and carton handling
- Injection-molded part extraction
- Packaging machinery
- Plastic component handling
- Automated assembly
- Robotic pick-and-place
Frequently Asked Questions
What is a single-bellows vacuum cup?
It is a suction cup with one bellows section that allows limited compression between the mounting point and sealing lip.
When should I use a single-bellows cup?
Use it where some height compensation or gentler contact is useful but the extra travel of multiple bellows is not required.
What materials are available?
The source range includes silicone, NBR, nitrile rubber and FDA-compliant metal-detectable rubber.
Are these cups used for cartons and paper?
Yes. Paper and carton handling are specifically identified as common applications.
Can single-bellows cups be used for injection molding?
Yes. The source description identifies molded-product extraction as a typical use.
How does a bellows cup compensate for height?
The bellows compresses as the cup contacts the product, providing controlled vertical movement.
How do I choose cup material?
Match material to temperature, surface, wear, food-contact requirements and the product being handled.
How do I choose the cup size?
Consider product weight, available flat sealing area, required holding force, vacuum level and machine acceleration.
