Selecting a style of
vacuum suction cup is
determined primarily by the product to be lifted.
Flat Vacuum Suction
Cups (listed
below) are typically designed to handle flat or slightly curved
surfaces. They offer fast attach/release times due to their small internal volume and are
good for handling heavy, horizontal loads. Flat vacuum suction cups with cleated bottoms to prevent
puckering are useful for handling flat, flexible loads such as cardboard and sheet metal.
Single (1.5)
Bellows Vacuum Suction Cups are ideal for
handling loads with uneven surfaces and irregular shapes. The bellows design compensates
for product irregularities and varied heights. They have longer attach/release times than
flat cups and are less suitable for lifting vertical loads.
Double (2.5)
Bellows Vacuum Suction Cups can be used in the
same applications as single bellows cups, but can accommodate greater product
irregularities and height variations. Double bellows cups are recommended only for
horizontal lifting of loads.
Flat
Vacuum Suction Cups Flat vacuum suction cups attach quickly due to the small volume
of air to be evacuated. They feature patterned knobs on the bottom to maximize capacity
and are excellent for holding flat, flexible materials without deformation. Relatively
stiff, the cup bodies retain their shape well in production applications. They are
excellent for use on fast cycle transfer systems. Use on flat or slightly curved surfaces,
and for horizontal or vertical lifting.
Vacuum Cup Materials:
The
standard materials are Nitrile (NBR) and Translucent Silicone (SIT).
