Overview
Comprehensive range of VUOTOTECNICA vacuum cups and accessories for industrial gripping, handling and clamping of flat, curved and irregular surfaces. Product families include cup-shaped, bellows, elliptical, star (SV), MAXIGRIP, VMG134, vulcanised-on support cups, foam cups and specialised series for packaging, food and fragile parts.

General features of rubber compounds
Comparative data on common compounds used in vacuum cups (commercial abbreviation, properties, temperature range, hardness, chemical resistance and food suitability). Typical standard compounds: N (natural rubber), A (oil‑resistant rubber), S (silicone). Special compounds include BENZ (chlorine/oil resistant), OF/Geranium (foam), NF (neoprene foam), SB (EPDM foam).

Vacuum cups with supports (small diameters)
Traditional cup-shaped cups for small components with flat or slightly curved surfaces. Typical diameters 4–9 mm. Cold‑fit on nickel‑plated brass or anodised aluminium supports with male threaded pin; easy replacement.

• Example product codes: 010410, 010510, 010610, 010707, 010810, 010907S, 000801, 000802

Vacuum cups with supports (10–45 mm)
Widely used for flat or slightly convex/concave surfaces. Diameters 10–45 mm. Supports in nickel‑plated brass or anodised aluminium; options for special compounds on request.

• Example product codes: 011010, 011210, 011510, 011810, 012010, 012210, 012515

Star Vacuum cups (SV series)
SV series for handling flat, flexible objects without deformation. Internal reinforcement sectors form a star-shaped bearing surface combining flexible lip and reinforced support. Can be fitted on male or female threaded aluminium supports.

• Example product codes: SV20SR, SV25SR, SV30SR, SV40SR, SV50SR

Maxigrip cups
Designed for robotic and automotive applications: round/oval, flat or bellows types, often with vulcanised support. BENZ compound offers high chlorine/oil resistance and a wide temperature range (approx. -40 to +170°C); design facilitates grip on oily/wet surfaces.

• Example product codes: VRP40A, VRP50A, VRP60A, VRP80A, VRP100A

Suction cups for packaging and films
Series for thin, lightweight and delicate items (plastic/paper bags, flow packs). Thin lip and internal cleats distribute vacuum to avoid deformation. Para compounds recommended for gentle adhesion.

• Example product codes: 011409, 0008240, 081409, 081410

Round flat and cleated cups
For wood, plastic panels, thin glass, marble and ceramic tiles. Low, slightly tilted lip and internal cleats reduce sucked air volume and prevent surface swiping. Cold‑fit on anodised aluminium supports; ring nut locking available.

• Example product codes: 017624, 019024, 0111024, 0115036

Vulcanised support cups
Used in automotive for moulded/drawn sheet metal. Ground lip for immediate grip and perfect vacuum seal; support vulcanised to the cup. BENZ often used for resistance to forming oils.

• Example product codes: 085040, 087540, 0810040, 0810050

Foam rubber cups (GERANIUM / NF neoprene)
Foam cups grip very rough surfaces while keeping elasticity over many cycles. Available with self‑adhesive backing for quick fixing. Working temperature examples: GERANIUM (OF) -40 to +80°C; NF neoprene -20 to +80°C.

• Example product codes: 014215, 016415, 019215, 0008147

Vacupredator and bags/packs cups
For gripping bags, packs and flexible containers. Anodised aluminium bodies with internal slotted plate and foam seal adapt to creases and prevent perimeter vacuum loss. Lifting force calculated for at least -75 kPa with safety factor 3.

• Example product codes: VP12OF1015, VP22OF1515, VP0612OF1015

VMG134 – suction cup for structured tiles
High‑density foam cup for textured tiles with anodised Anticorodal support. Self‑adhesive side, four attachment holes and two sealed vacuum connections; available in EPDM (SB), GERANIUM (OF) and NF neoprene variants.

• Example product codes: 01134134, VMG134, 0008479

Bellows, reinforced bellows and multi‑bellow cups
Bellows-type cups compensate for height variations and grip on inclined or delicate surfaces (baked goods, eggs). Double/reinforced bellows for heavy packaging; available cold‑fitted or vulcanised.

• Example product codes: 012030S, 013045S, 014055S, 015065S

Supports, adapters and accessories
Wide range of supports (nickel‑plated brass, anodised aluminium, galvanised steel), adapters (GAS↔metric, NPT), threaded grub screws with calibrated holes, anti‑slip supports, filters, O‑rings and fittings. Supports match internal cup profile and provide male/female axial pins for suction and fastening.

• Example accessory codes: 000801, 000802, 000803, 000804, 0008215

Special and application‑specific cups
Special shapes address sector needs: egg handling, grinding wheels, tight‑tolerance clamping for glass processing, Bernoulli non‑contact cups for fragile foils/semiconductors and custom solutions for specific tasks.
