Hydraulic Cylinder - Force from Pressure

Push / pull force of a hydraulic cylinder given working pressure, bore and rod diameter - the fundamental cylinder sizing equation.

HydraulicCylinderForce
Push force
785.4kN
Pull force
589.0kN
Formula, assumptions, and limits

Standard marine deck-machinery pressures 210–350 bar. Column-buckling check separately for long stroke rods. Differential cylinders have push:pull ≈ 1.3:1 for typical bore/rod geometry.
