💡Hydraulic cylinders typically operate at 100–350 bar — up to 175× higher than pneumatics. At 200 bar and Ø80mm bore a cylinder delivers over 100 kN (10+ tonnes). Always verify rod buckling for long strokes.
F [N] = A [cm²] × p [bar] × 10
P P → F p × A
Input
Cylinder bore iInternal bore diameter of the hydraulic cylinder in millimetres.
mm
Rod diameter iPiston rod diameter in millimetres. Typically 50–60% of bore diameter.
mm
Working pressure iHydraulic working pressure in bar. Typical range: 100–350 bar.
