Vacuum Cups and Suction Cups
Larger than 40mm
Suction Cups
(40mm - 188mm) for
End-of-Arm-Tooling (EOAT)
In
addition to our general purpose
vacuum cups and suction cups, ANVER offers an extensive line of small
vacuum cups and suction cups for end-of-arm-tooling. These are well suited to the
automation and handling processes of high technology industries, including
plastic injection molding sprue picker robots etc. Type, size, shape and material are
strictly determined by the end process use. Many of the cups listed below
will interchange with other manufacturers’ products. The -ESD cups on this
page are molded from
Electro-Static Dissipative Nomastat™ material. We
have more information on materials here.

The cup capacities shown
above ( *
) are
theoretical capacities based on 24"Hg at sea level with a safety factor of two (2)
and a
±
5% margin of error. This is
the US ANSI ASME Standard B30.20 for vacuum lifter specifications and is commonly used in North America
as a design capacity for vacuum components. When used in vertical
applications, take these values
and divide again by 2 to obtain a 4 to 1 safety factor per the ANSI
specifications. These are realistic working capacities when designing
equipment.
Other manufacturers use a pull-off
figure at 27"Hg to show a high capacity value for their cups. This is
accurate, but requires users to do all the math themselves to build in safety
factors. The
values are basically the same, but it is necessary to calculate the working
capacities with a safety factor via the following formula at sea
level:
Pull-off
value
(at
27"Hg) = ANVER's Listed Capacity x 2 x 1.125 (at 24"Hg)
For example:
ANVER vacuum cup number F52 has a rated capacity of 15.10 lb at
24"Hg. The pull-off capacity at 27"Hg for this cup would be
15.10 x 2 x 1.25 = 33.79 lbs. From this point, it is necessary to
calculate the safety factor based
on the vacuum level being used, and the altitude.
To ensure
safety, 80% of actual overall diameter is used when determining Load
Capacity.
