Industrial Vacuum Cups Contact Us

Vacuum cups provide a simple method of holding an object in a fixture or transporting an object from one position to another without danger of marring the surface finish of the object. Since vacuum cups are the first components to be selected within the design of a vacuum system, the design work begins there and then proceeds to other system components. EDCO manufactures vacuum cups in all sizes to meet your project’s exact specifications.

At EDCO USA, we design and test our own industrial vacuum cups. This allows us to fully understand vacuum suction cup capabilities. We provide high quality vacuum suction pads at reasonable prices, while providing personable, one-on-one customer service that is second to none.

Our vacuum pads offer the proven performance that you need to provide successful product transportation without the concern of surface damage.

Bellows Vacuum Suction Cups

Bellows vacuum suction cups are used when it is necessary to compensate for varying workpiece heights, to handle parts with uneven (concave, convex, or textured) surfaces, or easily damaged parts. Bellows vacuum cups can conform to curved or uneven workpieces such as pipes, bottles, containers, cylinders, car body components, flexing cardboard boxes, and more.

Double-Bellows Vacuum Suction Cups

Double-bellows vacuum suction cups provide a longer stroke than single-bellows vacuum cups for greater ability to compensate for varying workpiece heights. This increased ability to compensate for varying heights does come at the cost of stability.

Multi-Bellows Vacuum Suction Cups

Multi-bellows vacuum suction cups are made with shallow-fold bellows plus a thin, shallow sealing lip that allows it to conform to flexible packaging and other thin workpieces. The shallow-fold bellows cannot withstand deep vacuum unless it is fully collapsed. 

Bellows Flat Vacuum Suction Cups

Bellows flat vacuum suction cups combine a top bellows section with a slightly dished larger diameter flat-style cup having a heavy pattern of bottom cleats. Bellows flat vacuum pads are suitable for flat or gently curved surfaces.

Deep Vacuum Suction Cups

Deep vacuum suction cups are used for highly curved or irregular surfaces and can even seal against corners, edges, and spherical workpiece. Deep suction pads are unsuitable for use on flat surfaces because the lip will be overstretched, and the resultant scrubbing could leave marks on the workpiece.

Flat Vacuum Suction Cups

Flat vacuum suction cups are like universal cups except they have cleats on the bottom which serve as traction surfaces and support the workpiece being lifted to prevent or limit deformation. Flat cups have high stability and traction but a very short stroke. They should be used primarily for flat workpieces or sheet goods such as cardboard, corrugated board, and dry sheet metal. 

Flat-Concave Vacuum Cups

Flat-concave vacuum cups have a dished bottom plus conforming cleats for use with flat or slightly domed or convex workpieces. These industrial suction cups have slight angular compensation ability so they should always be picked up perpendicular to a flat workpiece surface.

Oval Suction Cups

Oval suction cups come in two styles. Oval concave (OC) vacuum cups are like universal cups except the cup is elongated to provide a larger surface area and thus a stronger grip. Whenever possible, use several round vacuum cups instead of oval suction pads since round vacuum cups are more forgiving of mounting misalignment and workpiece deflection.

Universal Vacuum Cups

Universal vacuum cups are like flat vacuum cups except they have no bottom cleats. As a result, deflection is higher than flat vacuum cups and the cup area exposed to vacuum becomes smaller as vacuum level deepens and the cup lips flatten out. Thin workpiece materials can be drawn in toward the cup center and essentially seal of vacuum from the universal vacuum cup lips so that the effective area becomes so small that the cup cannot pick up the workpiece safely.

Egg Vacuum Cups

Egg vacuum cups are double-bellows cups with a conical lower lip designed to gently grip eggs in a wide range of sizes. Common applications are sorting, incubation, rejection, or inoculation of eggs. Egg vacuum pads come in one material: brick-red, 30 Shore-A silicone rubber.

How Do Vacuum Cups Work?

Vacuum cups are made of rubber and included a flared lip to form a flexible seal against a workpiece allowing the cup to be evacuated with a vacuum pump. Several cups can be connected to a central pump or a small vacuum pump could be used for each cup.

When the vacuum cup is evacuated, an attraction force is developed that holds the cup to the surface of the workpiece. For a vertical cup axis, this attraction force is the lifting capacity. If the load is perpendicular to the cup axis (shear load), the attraction force must be multiplied by the appropriate coefficient of friction to determine an allowable shear load. In either case, an additional factor-of-safety must be applied for prudent design. When rapid movement occurs in automation systems, a designer must consider the combined magnitude of both lifting and shear loads when selecting components.

  2. Intermittent service temperature. Intermittent service temperature may possibly be higher. Determine via testing under actual conditions.
  3. Weight of Nitrile / TPV cup without fitting is tabulated. Use the ratio multiplier for other materials.
  4. The terms "non-staining" and "non-marking" refer only to the cup material. Airborne aerosols that attach to the cup surface or direct cup contact with dirty surfaces can result in residue transfer marks. Proper maintenance is important. Use only soap and water to wipe cups clean after installation and periodically afterward to remove airborne contaminants.
  5. EDCO products are made with synthetic, rubber-like materials. As such, EDCO products do not contain latex.
  6. All figures for shear load are 18 inHg using a 0.5 coefficient of friction. Adjust coefficient of friction to suit your conditions then apply a generous factor of safety (3:1 or greater) to shear loads.
