VACUUM CUPS
Vacuum Cup Selection Guide
Horizontal Lift = 2
Safety factor of 2 is recommended
when cup face is in horizontal position.
Vertical Lift = 4
Safety factor of 4 is recommended
when cup face is in a vertical position.
Safety Factor=2
Safety Factor=4
Force Area

Safety Factor * Lbs (Kg)
Convert "Hg TO PSI,
Divide by 2
(2Hg" = 1 PSI)
Area =
p(d /4²)
p = 3.14

As is true in most vacuum applications, there is more than one
correct answer.
In order to successfully find the best cup(s) and generators for a
specific task,
it is helpful to review the guidelines below.
Vacuum Cup Sizing
Choose the cup size, quantity, material and style based on the
size of the object being handled, its weight, orientation, surface
temperature, conditions and space available to mount the cups.
I. Determine the cup size by using the "Vacuum Cup Holding Force
Calculation:"
Force = Pressure x Area
F = the weight of the objects in lbs(kg) multiplied by the safety
factor, see below.
P = the expected vacuum level in PSI (Kpa) (2Hg" = 1 PSI)
A = the area of the Vacuum cup measured by in

Safety Factors:
Always include safety factors when calculating liing capabilities.
