Vacuum Cup Materials Information and Product Specifications

VACUUM CUP MATERIAL:

Chloroprene (C): Good wear resistance properties, 0-zone, -40º to 230ºF (-40º to 110ºC)
Polyurethane (P):  Best wear resistance, super long life, oil resistant, -58º to 248ºF (-50º to 120ºC)
Nitril Ruber (N): Good wear resistance properties, oil resistant, -20º to 225ºF (-50º to 120ºC)
Silicon (S): Soft Material, especially good for rough/textured surfaces, -86º to 392ºF (-65º to 200ºC)
Viton (V): High resistance against compression and tension, -23º to 446ºF (-30º to 230ºC)
Polyurethane (Pu): Soft polyurethane, best on textured surfaces, good wear resistance, oil resistant, -68º to 167ºF (-55º to 75ºC)
Dual Durometer Polyurethane (DDP): Soft seal with stiffer base, best on textured surfaces with high vacuum levels, good wear and oil resistance, -50º to 122ºF (10º to 50ºC)
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
