ENGINEERING GUIDE

Use the Pneumatic Cylinder Stroke Time Calculator to find extend/retract time from stroke, bore and available flow. The calculator uses Stroke, Bore diameter, Rod diameter, Reference air flow and Working pressure and reports stroke time; cycle time.

How to interpret the result

Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are stroke time; cycle time. Change one input at a time when comparing scenarios so the effect of each variable remains clear.

Formula and methodology

PneumaForge applies this verified method: t=V/Q using line-condition volume/flow. The functional engine is shared with related tools in the cylinder-flow family, while this page solves the specific intent represented by pneumatic cylinder stroke time calculator.

t=V/Q using line-condition volume/flow

Variables and inputs

  • Stroke
  • Bore diameter
  • Rod diameter
  • Reference air flow
  • Working pressure
  • Direction

Worked example

Reproducible example: start with the calculator's default values (Stroke = 500; Bore diameter = 100; Rod diameter = 40; Reference air flow = 500) and calculate the result. Then change the variable most relevant to your application and compare the new stroke time; cycle time against the baseline.

Assumptions and limits

Steady average flow; real acceleration, valve dynamics and cushioning can make measured times longer.

Engineering tips

  • Use differential pressure at the actuator rather than compressor discharge pressure when losses are material.
  • For retract force, account for rod area instead of using full piston area.
  • Check manufacturer load, cushioning and mounting limits before selecting hardware.
  • Keep the inputs used for pneumatic cylinder stroke time calculator on a consistent engineering basis before comparing alternatives.

Frequently asked questions

What does the Pneumatic Cylinder Stroke Time Calculator calculate?

It is designed to find extend/retract time from stroke, bore and available flow. The reported outputs are stroke time; cycle time.

What inputs does the Pneumatic Cylinder Stroke Time Calculator use?

The calculator uses Stroke, Bore diameter, Rod diameter, Reference air flow and Working pressure. Only use values that represent the same operating condition or design case.

What formula or method is used?

The calculation follows: t=V/Q using line-condition volume/flow. The page also states the assumptions that define where the method is valid.

Which assumptions can affect the result?

Steady average flow; real acceleration, valve dynamics and cushioning can make measured times longer.

Can I use different units?

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.
