Pneumatic Cylinder  Excerted Force vs. Pressure
Force excerted by pneumatic air cylinders vs. air pressure cylinder size  online calculator.
Single Acting Cylinder
The force exerted by a single acting pneumatic cylinder can be expressed as
F = p A
= p π d^{2 }/ 4 (1)
where
F = force exerted (N)
p = gauge pressure (N/m^{2}, Pa)
A = full bore area (m^{2})
d = full bore piston diameter (m)

Example  Single Acting Piston
The force exerted by a single acting pneumatic cylinder with 1 bar (10^{5} N/m^{2}) and full bore diameter of 100 mm (0.1 m) can be calculated as
F = p π d^{2 }/ 4
= (10^{5} N/m^{2}) π (0.1 m)^{2} / 4
= 785 N
= 0.785 kN

Double Acting Cylinder
The force exerted by double acting pneumatic cylinder on outstroke can be expressed as (1). The force exerted on instroke can be expressed as
F = p π (d_{1}^{2}  d_{2}^{2}) / 4 (2)
where
d_{1} = full bore piston diameter (m)
d_{2} = piston rod diameter (m)

Example  Double Acting Piston
The force exerted from a single acting pneumatic cylinder with 1 bar (10^{5} N/m^{2}), full bore diameter of 100 mm (0.1 m) and rod diameter 10 mm (0.01 m) can be calculated as
F = p π (d_{1}^{2}  d_{2}^{2) }/ 4
= (10^{5} N/m^{2}) π [(0.1 m)^{2}  (0.01 m)^{2}] / 4
= 778 N
= 0.78 kN
 instroke capacity is reduced compared to outstroke capacity  due to the rod and reduced active pressurized areal
