SI UNITS, SYMBOLS AND DIMENSIONING
Lifting force of vacuum pads
How to calculate the theoretical lifting force
of vacuum pads at different vacuum.
F = Lifting force with safety factor (N)
A = Pad area (cm
2
)
t = Safety factor (horizontal contact surface: 2–4;
vertical contact surface: 4–8)
As a complement to these formulas, you can nd the lift-
ing force at different vacuum in the table below.
Note! The values you get from the table should be
multiplied by
1
t
as in the above formulas.

o be able to choose the correct dimensions on the
vacuum pads, you should know the different vacuum
pads theoretical lifting force at different vacuum levels.
Here we present formulas and a table that you can
use as a basis for your calculations.
