Calculate pneumatic cylinder force or air cylinder force from bore diameter, rod diameter and working pressure. The calculator reports extend force, retract force and effective force, with explicit loss allowance and unit conversion.
Use extend force for the full piston area and retract force for the annular area after subtracting the rod. Effective force applies only the explicit loss allowance you enter; PneumaForge does not hide friction or safety factors inside the result.
PneumaForge applies F = P×A. Extension uses the full piston area; retraction uses the annular area after subtracting rod area. The optional loss allowance is applied explicitly so theoretical and effective air-cylinder force remain distinguishable.
F = P×A; annular area on rod side; optional documented loss allowanceReproducible example: start with the calculator's default values (Bore diameter = 100; Working pressure = 6; Rod diameter = 40; Direction = extend) and calculate the result. Then change the variable most relevant to your application and compare the new extend force; retract force; effective force against the baseline.
Pressure is differential pressure across piston. Friction/spring/losses are separate explicit inputs, never hidden constants.
It is designed to find theoretical/effective cylinder force from bore and pressure. The reported outputs are extend force; retract force; effective force.
The calculator uses Bore diameter, Working pressure, Rod diameter, Direction and Explicit force loss. Only use values that represent the same operating condition or design case.
The calculation follows: F = P×A; annular area on rod side; optional documented loss allowance. The page also states the assumptions that define where the method is valid.
Pressure is differential pressure across piston. Friction/spring/losses are separate explicit inputs, never hidden constants.
Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
Yes. Air cylinder and pneumatic cylinder normally describe the same actuator type. Force is based on pressure multiplied by effective piston area, with rod area reducing retract force.
