eng.hydraulic-cylinder-force Calculator
Calculates hydraulic cylinder force, pressure, and flow rate from bore diameter, rod diameter, and system pressure. Hydraulic cylinder push force = π/4 × bore² × pressure — the annulus area on the rod side means retraction force is less at the same pressure.
Inputs
Bore Diameter Mm
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Rod Diameter Mm
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Pressure Bar
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
Stroke Type
Reference formula or conversion factor shown for context.
Results
cylinder force (kN)
Sample size or count used in the calculation.
stroke type
The classification or type assigned based on the inputs.
area used (cm²)
The computed two-dimensional surface area.
bore area (cm²)
The computed two-dimensional surface area.
annulus area (cm²)
The computed two-dimensional surface area.
F = P × A
