Vacuum suction cups
Vacuum technology
Aventics vacuum suction cups are available in three form families: flat round suction cups FSR series (75-300 mm diameter), flat standard suction cups FSG (95-150 mm), and bellows suction cups BSG/BSA (85-150 mm). Materials include NBR (standard compressed air), MQ (silicone rubber, food-grade), PUR (soft, for sensitive surfaces), and HNBR (for high-temperature applications). Connections range from G1/4 to G1. The IN (internal connection) and EX (external connection) versions determine whether air is routed inside or outside the gripper arm.
| Series | Form | Diameter mm | Materials |
|---|---|---|---|
| FSR | Flat, round | 75, 100, 150, 225, 300 | CR, MQ, HNBR |
| FSG | Flat, standard | 95, 120, 150 | NBR, MQ |
| BSG | Bellows | 85, 110, 150 | NBR, MQ, PUR (IN/EX) |
| BSA | Bellows, asymmetric | 85 | PUR (IN/EX) |
Material selection is governed by workpiece surface condition, temperature, and media compatibility. NBR is the standard material for dry compressed air and general industrial applications. MQ (silicone rubber) is food-grade and heat-stable to approximately 180 °C. PUR offers high flexibility for sensitive or uneven surfaces. HNBR is suitable for elevated temperatures and oily environments. Bellows suction cups (BSG/BSA) compensate for angular deviations and height differences without an external angle compensator unit. The internal connection (IN) enables cleaner line routing through the gripper arm.
Typical applications: Handling of PCBs and SMD components in electronics production (NBR, MQ), gripping of glass panes and ceramic tiles (FSR, large diameters), transport of food packaging and food items (MQ, food-grade), handling of painted and polished metal surfaces in automotive finishing (PUR), and pick-and-place operations in printing and packaging automation.
