Series HV

Robot Vacuum Grippers, Suction Cups & Vacuum Generators

HITREE HV series covers single vacuum suction cups for robots and complete multi-cup vacuum grippers. Vacuum handling is the fastest way to pick flat, smooth parts such as sheet metal, glass, panels and cartons, with no risk of jaw marks.

Types

Vacuum Suction Cups & Generators range

Vacuum suction cups for robots, vacuum generators and complete multi-cup vacuum grippers for sheet metal, cartons, glass and panels.

Flat suction cups

Low height and high lateral stability for flat, rigid surfaces such as sheet metal, glass and boards.

Bellows suction cups

1.5 or 2.5 folds adapt to curved and uneven surfaces and compensate for height differences.

Multi-cup vacuum grippers

Aluminum profile frame with several cups, built to your part size, for panels, cartons and car body parts.

Vacuum generators

Compressed-air vacuum ejectors that create vacuum right at the tool, with no electric pump. Fast response and low weight on the robot.

Spring buffers & holders

Level compensators and cup holders that protect the cup and part when the robot lands on the surface.

HV series — theoretical holding force per cup (horizontal lift, −60 kPa, no safety factor)
Cup diameter	Type	Effective area	Holding force	Materials
Ø 10 mm	Flat / bellows	79 mm²	4.7 N	NBR, Silicone
Ø 20 mm	Flat / bellows	314 mm²	19 N	NBR, Silicone, PU
Ø 30 mm	Flat / bellows	707 mm²	42 N	NBR, Silicone, PU
Ø 40 mm	Flat / bellows	1,257 mm²	75 N	NBR, Silicone, PU
Ø 60 mm	Flat / bellows	2,827 mm²	170 N	NBR, Silicone, PU
Ø 80 mm	Flat	5,027 mm²	302 N	NBR, PU
Ø 100 mm	Flat	7,854 mm²	471 N	NBR, PU

Holding force = vacuum × cup area. Divide by a safety factor of at least 2 for horizontal lifting and at least 4 for vertical (shear) lifting.

Values shown are typical. Ask us for the datasheet of the exact model before you order.

Features

Why choose HITREE HV series

Three cup materials

NBR for oily sheet metal, silicone for food and high temperature, PU for wear resistance and long life.

No marks on the part

Soft lips and anti-mark compounds for painted, polished and glass surfaces.

Light weight

Aluminum frames keep the end effector light, so you can use a smaller robot or run faster.

Easy replacement

Cups thread onto standard fittings and change in seconds during maintenance.

Applications

Typical applications

Sheet metal loading for press brakes and lasers
Carton and bag palletizing
Glass and panel handling
Car body part transfer

Selection

How to choose

Match the surface
Flat cups for flat rigid parts, bellows cups for curved or uneven surfaces and height differences.
Match the material
Oily parts need NBR, food contact needs silicone, abrasive surfaces need PU.
Size the cups
Total holding force ÷ safety factor must exceed the part weight plus acceleration forces.

FAQ

Vacuum Suction Cups & Generators: common questions

How do I calculate the holding force of a vacuum suction cup?

Multiply the vacuum level by the effective cup area. At −60 kPa a Ø 40 mm cup gives about 75 N in theory. Then divide by a safety factor of 2 to 4 depending on lift direction.

Flat or bellows suction cup?

Flat cups are stiffer and more precise on flat parts. Bellows cups follow curved surfaces, absorb height differences and give a small lifting motion when vacuum is applied.

Can you build a complete vacuum gripper for my part?

Yes. Send the part size, weight and material, and we design the frame, cup layout and vacuum circuit.

Which vacuum source should I use?

Compressed-air ejectors suit most robot cells because they are light and need no electrical pump. For porous parts with high leakage, a vacuum pump or blower is better.
