Maxigrip cups (round flat and bellows)

• Designed as alternative for robot-automotive field; round/oval, flat and bellows-type; supports vulcanised onto cup.
• Flexible outer lip combined with bellows features allows adaptation to flat, concave, convex surfaces without deforming thin objects.
• Internal design facilitates drainage of oil and water; high friction coefficient for oil-covered metal sheets and wet glass or marble.
• Made with exclusive BENZ compound: hardness 60-75°Sh, working temperature -40 to +170°C, stain-resistant, excellent abrasion, water and chlorine-containing oil resistance.

• Product codes: VRP40A VRP50A VRP60A VRP80A VRP100A VRP125A VRS40 VRS50 VRS60 VRS80 VRS100 VRS125

Suction cups for handling plastic films, flow packs and packaging

• Series designed for thin, lightweight, delicate objects (plastic or paper bags).
• Especially thin lip for adaptation to shape changes; internal cleats distribute vacuum evenly and prevent thin materials from being deformed or sucked into central hole.
• Para compound recommended for best adhesion and gentleness on material.
• Product codes include: 011409 0008239 0008240 081409 081409F 011410 ...

Round flat vacuum cups with supports (various sizes)

• Designed for wooden or plastic panels, thin glass or marble sheets, fragile metal sheets, ceramic tiles.
• Low, strong and slightly tilted lip avoids swiping; internal cleats reduce air volume to be sucked and create supporting surface preventing deformation and slipping.
• Cold fitted onto anodised aluminium support and locked by ring nut. Larger cups may include M8 threaded hole for insertion of grub screw to reduce air to be suctioned.
• Product codes examples: 017624 019024 0111024 0115036 0008108 ...

Vacupredator cups for gripping bags, packs and flexible containers

• Designed to grip flexible containers (paper/plastic) containing powders, granulated products, liquids, etc.
• Made of anodised aluminium, equipped with slotted plate and special foam rubber seal to adapt to creases and prevent perimeter vacuum losses.
• Calculated lifting force for vacuum at least -75 KPa with factor of safety 3.
• Product codes: VP12OF1015 VP22OF1515 VP0612OF1015 VP0916OF1030 VP0921OF1030 VP1520OF1030 VP2030OF1530 VP3040OF1530

VMG134 suction cup for structured tiles

• Designed for automatic sorting machines handling textured tiles; shape and material ensure secure grip on uneven/rough surfaces.
