## Determine The Amount of Force Your Hydraulic Cylinder Will Produce

The amount of force a hydraulic cylinder will be able to generate is equal to the hydraulic pressure times the “effective area” of the cylinder.

The force produced by a double acting hydraulic piston on the rod side (1) can be expressed as

F1 = (π (d22 - d12) / 4) P1 (1)

where as

• F1 = rod force (lb, N)
• d1 = rod diameter (in, m)
• d2 = piston diameter (in, m)
• P1 = pressure in the cylinder on the rod side (lff/in2 (psi), N/m2 (Pa))

The force produced on opposite side of the rod (2) can be expressed as

F2 = (π d22 / 4) P2 (2)

where as

• F2 = rod force (lb, N)
• P2 = pressure in the cylinder (opposite rod) (lff/in2 (psi), N/m2 (Pa))

## How to Calculate Hydraulic Cylinder Tonnage

A hydraulic cylinder can exert enormous forces because of the way fluids act under pressure. With a little simple geometry you can calculate a cylinder’s force in pounds or tons. The pound force is the product of the fluid pressure in psi multiplied by the cross-sectional area of the piston. To get the hydraulic cylinder tonnage, divide the pound force by 2,000.
