Selection guide for Suction cups
Metric   Imperial

Bellows

Suitable for height differences and slightly uneven or curved surfaces.


teaser_pigrip_configurable
piGRIP® Configurable suction cups
The piGRIP® is a unique configurable suction cup concept with individually optimized parts for gripping, lifting and height compensation. Also a large selection of fittings makes it ready to fit new machines and easy to retrofit existing cups. The fittings available are both threaded and push on fittings.
teaser_B_bellows_5-150
B - Bellows (5–150 mm)
Several short bellows cups in one lifting device can handle objects with height differences and varying shapes. The bellows also provide a slight lifting movement to separate thin items. Materials used are silicone, conductive silicone, semi-conductive EPDM, chloroprene, HNBR and nitrile-PVC.
teaser_B_Bellows_DURAFLEX
B - Bellows DURAFLEX® (10–110 mm)
Several short bellows cups in one lifting device can handle objects with height differences and varying shapes. The bellows also provide a slight lifting movement to separate thin items.
teaser_B_bellows_FDA
B - Bellows FDA & EU (5–150 mm)
The material is approved by  FDA (FDA 21 CFR 177.2600. ) and meets EU's regulation EU 1935/2004. Most of the cups are transparent with no addition of pigments.
teaser_b-mf--bellows_mark_free
B-MF - Bellows Mark Free (15–50 mm)
The same applications as for short bellows. Also suitable for smooth objects requiring a very clean surface. Only light weight objects should be handled when the lifting force is parallel to the surface.
teaser_bf-bellows_flat
BF - Bellows Flat DURAFLEX® (80-110 mm)
Suitable for uneven and porous surfaces such as cardboard, etc. DURAFLEX® suction cups are manufactured in a specially developed material that features the elasticity of rubber and wear resistance of polyurethane. The material of the DURAFLEX® is mark-free.
teaser_bff-bellows_flat_friction
BFF - Bellows Flat Friction (40–110 mm)
The BFF design is suitable for oily surfaces, uneven/curved surfaces or if level compensation is needed, for example in de-stacking applications. The flat inner support gives stability during movement in any orientation.
teaser_BFFT
BFFT - Bellows Flat Friction for thin-sheets (50–90 mm)
The BFFT design is the best choice for very thin metal sheets (0.6 - 0.8 mm) to avoid risk for dents. The cups work great on flat and uneven/curved surfaces or if level compensation is needed, for example in de-stacking applications.
