Vacuum Cup Materials Information and Product
Specifications
VACUUM CUP
MATERIAL:
Chloroprene (C):
Good wear resistance properties, O-zone
resistant, -40° to 230°F (-40° to 110°C)
Polyurethane (P): Best wear resistance, super
long life, oil resistant, -58° to 248°F (-50° to
120°C)
Nitril Rubber (N): Good wear resistance
properties, oil resistant, -20° to 225°F (-29°
to 107°C)
Silicone (S): Soft material, especially good for
rough/textured surfaces, -86° to 392°F (-65° to
200°C)
Viton (V): High resistance against compression
and tension, -23° to 446°F (-30° to 230°C)
Polyurethane (Pu): Soft polyurethane, best on
textured surfaces, good wear resistance, oil
resistant, -68° to 167°F (-55° to 75°C)
Duel Durometer Polyurethane (DDP): Soft seal
with stiffer base, best on textured surfaces
with high vacuum levels, good wear and oil
resistance, -50° to 122°F (10° to 50°C)
|

Lifting
Capacity
The lifting capacity of a vacuum cup can be
theoretically determined at sea level by
using the following formula:
C=.393xD2xV
N
C= Lifting Capacity (lbs.)
D=Cup Diameter (in.)
V=Vacuum Level (in Hg)
N=Desired Safety Factor |
Safety
factor for horizontal lifting
applications should be at least (2).
Vertical lifting applications should
have a safety factor of at least (4).
NOTE:
This formula will give theoretical
lifting capacity only. Actual lifting
capacity should always be verified by
user. |
|
Sizing Vacuum
Cups
When sizing cups there are three crucial
factors to consider. These are vacuum level,
number of cups, and the desired safety
factor. Cup diameter can be determined by
using the following formula:
 |
D=Diameter
of vacuum cup (in.)
M=Mass of lifting product (lbs.)
V=Vacuum Level (in Hg)
N=Safety Factor
U=Number of Cups |
