Choose force, pressure, bore geometry or hydraulic speed, enter the displayed inputs, and select the answer unit. Hydraulic modes distinguish full bore area from rod-side annular area.

Use the effective piston area for the side being pressurized.

Ideal force and speed: opposite-side gauge pressure is zero; friction and losses are excluded. This does not establish a cylinderโ€™s rated pressure or safe load.

Cylinder Pressure Formula

The following formula is used to calculate the Cylinder Pressure. 

Pc = Fc / Ac
  • Where Pc is the Cylinder Pressure (N/m^2)
  • Fc is the cylinder force (N) 
  • Ac is the cylinder area (m^2) 

To calculate ideal cylinder pressure, divide force by the effective area: full bore area for extension or annular area for retraction. Opposite-side gauge pressure is assumed zero; friction and other losses are excluded. This estimate does not establish rated working pressure or a safe load.

How to Calculate Cylinder Pressure?

The following two example problems outline how to calculate the Cylinder Pressure.

Example Problem #1:

  1. First, determine the cylinder force (N). In this example, the cylinder force (N) is given as 400.
  2. Next, determine the cylinder area (m^2). For this problem, the cylinder area (m^2) is given as 15.
  3. Finally, calculate the Cylinder Pressure using the equation above: 

Pc = Fc / Ac

Inserting the values from above and solving the equation: 

Pc = 400 / 15 โ‰ˆ 26.666667 (N/m^2)


Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

cylinder force (N) = 560

cylinder area (m^2) = 50

Entering these values yields:

Pc = 560 / 50 = 11.2 (N/m^2)
