Suction Cups with 1,5 Bellows Ø 5 to 78 mm, VSA series
Presentation
VSA series suction cups with bellows combine the advantages of flat suction cups with increased deflection, flexibility and precision. Used for gripping slightly concave or convex objects.
• Flexibility
• Precision
• Deflection

For delicate gripping requiring a very fl exible lip (opening bags, gripping tins and flexible aluminum or plastic bottles, etc.), we recommend using 35 Shore A white silicone, SIB.

The possible «suction cup+fitting» combinations are available on the documentation to download here.
