Calculate bore size, stroke length, working pressure, force output, and oil volume
Enter cylinder bore and working pressure to calculate the theoretical output force. Force = Pressure × Area
Force (kN) = Pressure (bar) × π × (Bore (mm) / 2)² × 10
Enter cylinder bore and required force to calculate the necessary working pressure.
Pressure (bar) = Force (kN) × 10 / (π × (Bore (mm) / 2)²)
Enter required force and available pressure to calculate the minimum cylinder bore size needed.
Bore (mm) = 2 × √(Force (kN) × 10 / (Pressure (bar) × π))
Enter cylinder bore and stroke length to calculate the oil volume required for one full stroke extension.
Volume (L) = π × (Bore (mm) / 2)² × Stroke (mm) / 1,000,000
Common standard bore sizes for hydraulic cylinders (mm and inches):
