Hydraulic cylinder calculator

Pick one calculation: force, flow and power, inch speed, or buckling. Force and flow stay in metric units. Speed uses inches and gpm and is not converted to mm/s. Buckling uses only the unit system you select.

Calculation
Force

Bore and rod are millimeters. Pressure is N/mm2 only. Pump bar is not used in this calculation.

Force

Push force 19634.9541 N

A = (pi / 4) * D^2. Force = P * A.

Pull force 14726.2156 N

Annulus = (pi / 4) * (D_bore^2 - D_rod^2).

Metric tonnes 2.0022 t

Metric tonnes = force_N / 9806.65

Only the selected calculation is shown. Steel E is used only when you enter it for buckling. Inch speed is not converted to mm/s.
