Fast, Stable Vacuum Gripping for Smooth Flat Surfaces
Flat vacuum suction cups are designed for rapid gripping and release on relatively smooth, flat products. Their low internal volume helps them evacuate quickly, making them well suited to high-speed lateral transfer and automated handling of materials such as sheet metal, glass and rigid plastic parts.
PneumaticHub offers flat cup options in materials such as nitrile and specialty silicone for applications with different wear, temperature, marking and food-contact requirements. Correct cup sizing and vacuum flow are important for safe, repeatable handling.
Why Choose Flat Vacuum Cups?

Frequently Asked Questions
What are flat vacuum suction cups best used for?
They are best suited to smooth, relatively flat products where fast evacuation and stable gripping are required.
Why are flat cups good for high-speed handling?
Their small internal volume can build and release vacuum quickly, supporting short machine cycle times.
Can flat suction cups handle sheet metal?
Yes. Sheet metal transfer is a common application when cup material, size and vacuum level are properly selected.
Can they be used on glass?
Yes. Flat cups are widely used for glass, with cup material chosen to minimize marking and provide reliable sealing.
When should I use a bellows cup instead?
Use a bellows cup when more compliance, height compensation or adaptation to curved or uneven parts is required.
How do I size a flat suction cup?
Calculate required holding force based on product weight and machine acceleration, then apply an appropriate safety factor.
What cup materials are available?
Common options include nitrile and silicone, with specialty compounds available for certain applications.
