Calculation reference

What this tool checks.

Available free-air flow is converted to working-pressure volume before estimating piston speed.

Inputs

  • Bore diameter
  • Rod diameter
  • Stroke length
  • Flow
  • Direction
  • Pressure

Outputs

  • Stroke time
  • Estimated speed
  • Actual working flow
  • Effective area

Engineering guide

Use the result with the right context.

Use your application data for a preliminary estimate, then check the result against the relevant technical or official guidance.

Calculation workflow

  1. Enter the known application values, including Bore diameter, Rod diameter, Stroke length.

  2. Run the calculation using one consistent set of units and reference conditions.

  3. Review Stroke time, Estimated speed, Actual working flow, then compare the result with the component datasheet and application margin.

Assumptions and limits

  • Use gauge pressure at the actuator and account separately for downstream back pressure.

  • Confirm mounting, side load, cushioning, duty cycle, and catalog limits before final cylinder selection.

FAQ

Common review questions.

01Tool noteWhy use this instead of the speed calculator?

This tool focuses on one direction and one target stroke, which is useful when checking a specific motion step in a machine cycle.

02Tool noteWhat can make the real stroke slower?

Undersized valves, long tubing, restricted exhaust, small mufflers, low supply pressure, high load, and cushion settings can all slow the actual stroke.

03Tool noteWhat should I verify after using the Stroke Time Calculator?

Check the entered units and reference conditions, then compare the calculated outputs with manufacturer ratings, application safety margins, transient loads, installation losses, and measured machine performance.
