Air Cylinder Force Calculator (Pneumatics)
Pneumatic cylinder force calculator. Computes push and pull output force in pounds force (lbf), Newtons (N), and kgf based on bore diameter, rod diameter, air pressure (PSI), and seal efficiency.
Air Cylinder Force Calculator (Pneumatics)
Calculate the theoretical and effective push (extension) and pull (retraction) force of single and double acting pneumatic cylinders.

Bore area minus rod areaPneumatic Cylinder Physics
Force generated equals pressure multiplied by the surface area ($F = P \times A$). Notice that on retraction, the rod occupies space inside the air chamber, reducing the available surface area. This is why pneumatic cylinders always exert slightly less pull force than push force.
How to Use Air Cylinder Force Calculator (Pneumatics)
Enter Bore & Rod Sizes
Input cylinder bore diameter and piston rod diameter in inches.
Set Pressure
Input operating air pressure in PSI (typically 80-100 PSI for shop air).
View Extension & Retraction Forces
Inspect push force, pull force, and piston surface areas.
