Bellow Vacuum Pads
Our bellows suction cups enable the secure gripping and handling of workpieces with varying heights, uneven surfaces, or delicate materials. Their flexible bellows design compensates for height differences while providing gentle and reliable handling. Available in various diameters, materials, and numbers of bellows folds, they are suitable for a wide range of demanding vacuum applications.
There are 95 products.
Material Properties & Temperature Resistance
Each series of suction cups is designed and engineered for different applications. Below is a table to help you determine the ideal suction cup material:
| Material | Temp. (Short time) | Temp. (Long time) | Wear resistance | Oil resistance | Weather and ozone |
| NBR | -20°C to +110°C | -10°C to +80°C | Excellent | Excellent | Good |
| Silicone | -40°C to +200°C | -30°C to +180°C | Unsuitable | Unsuitable | Excellent |
| Polyurethane | +10°C to +50°C | +10°C to +40°C | Excellent | Excellent | Excellent |
| Natural Rubber | -20°C to +80°C | -10°C to +60°C | Excellent | Unsuitable | Fair |
| Hightemp. Silicone | -70°C to +280°C | -50°C to +230°C | Excellent | Excellent | Excellent |
| Fluorine Rubber | -10°C to +230°C | -5°C to +200°C | Excellent | Good | Good |
| EPDM | -30°C to +150°C | -20°C to +120°C | Good | Unsuitable | Excellent |
Shore hardness
When handling workpieces, the material of the vacuum pad is critical for durability, cycle time, and product integrity. The Shore hardness (Shore A for elastomers) determines how "soft" or "hard" the vacuum pad is.
| Shore-Hardness | Property | When should it be used? |
| 30°-40° | Very soft | Irregular, uneven surfaces; delicate products |
| 40°-55° | Soft | Standard applications; balanced ratio |
| 55°-70° | Hard | Smooth surfaces; fast cycles; heavy loads |
