Bell-type Suction Cups Ø 40 à 100 mm, CTC Series
Presentation
The CTC Series high-performance bell-type suction cups have been specifically developed to meet the production requirements of applications in the automotive sector. The bell shape of the CTC Series suction cups gives them significant deflection compared to traditional flat suction cups and guarantees better adaptability to the profiles of parts with long lines. The internal stops ensure excellent sliding resistance and allow the gripping of parts without deformation.
The characteristics of the CTC Series suction cups optimize production in all areas of operation.

Extreme resistance to slippage and acceleration.
• Excellent adaptation to convex surfaces and angular shapes.
• High deflection compared to standard flat suction cups due to the
bell shape.
• Anti-slip cleats ensure precise positioning of oily sheets.
• Particularly suitable for use on high-speed presses, for high speeds
and handling of large parts (e.g. body side, roof, doors).
• Deformation-free gripping of thin sheets thanks to central stops.
Main Advantages
• 4 diameters for optimal adaptation to each application.
• Excellent resistance to wear and oil thanks to thermoplastic polyurethane (TPU).
• Low weight due to polyamide insert.
• Sealing lips.
• Integrated O-ring seal (male cylindrical G3/8" and square 32 versions).
• Double tightening: 2 flat 22 mm and one hollow hexagonal 6 mm.
