How to calculate hydraulic cylinder force?

Force F = P × A × η, where P is system pressure (MPa), A is piston area (cm²), η is efficiency (~0.9). For a 100mm bore at 16MPa: F ≈ 113 kN.

What is cylinder area ratio?

Area ratio = bore area / annular area. It determines regenerative circuit characteristics. Common ratios: 1.3-2.0.

Calculate thrust, retract force, flow rate, and piston rod buckling stability.
