Cylinder force calculator

Force is pressure times piston area. Enter a cylinder bore and the applied line pressure in bar or MPa to get the ideal output force — the quantity that, divided by mould area, becomes the effective mounting pressure.

Cylinder bore diameter

Piston diameter of the cylinder.

Applied pressure

Line pressure acting on the piston.

Force: 4,712 N
Force: 4.71 kN
≈ equivalent load: 481 kgf

Theoretical / ideal calculated values. Friction, seal losses, mechanism geometry, actual piston area, rod-side actuation and regulator behaviour alter real results. Not a certified machine specification.

The formula used

A = π × D² / 4          (piston area)
F = P × A               (force = pressure × area)
1 kgf = 9.80665 N

1 bar = 0.1 MPa = 100,000 Pa. kgf equivalent uses g = 9.80665 m/s². Ideal, loss-free force.
