Cylinder Force Calculator.

How do you calculate the extension force of a cylinder?

To find the extension force of a cylinder, use the
cylinder force formula:

Extension Force (lbs) = Piston Area x PSI

PSI = Pressure (Pounds per Square Inch)

r = Radius

Piston Area = (Pi X r^{2})

To find the retraction force of a cylinder, use the

cylinder retraction force formula:

Retraction Force (lbs) = (Piston Area - Rod Area) x PSI

Example: For a double-acting cylinder with a piston radius
of 2 inches,

a rod radius of 1 inch, 2000 psi
supplied to the base on extension,

and 2500 psi supplied
to the rod end for retraction:

Extension Force = (3.1416 x 2^{2}) x 2000
psi

Extension Force = 25,132.8 lbs

Retraction Force = Annulus x 2500 psi

Annulus = (3.1416 x 2^{2}) - (3.1416 x 1^{2})
=

Retraction Force = 23,562 lbs
