Flat Suction Cups

Flat vacuum 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. The cleats limit deflection and maintain a larger exposed area to vacuum for a firm grip on the workpiece.

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 vacuum cups will not work well with thin workpieces such as plastic sheet goods or flexible packaging.

Flat vacuum cups have very little angular compensation ability so they should always pick up perpendicular to a flat workpiece surface.
