Pneumatics · Preliminary sizing

Pneumatic cylinder: force, bore and air consumption

Estimate extension and retraction force, required bore, and normalised air consumption for a pneumatic cylinder.

ISO6358

Inputs

Operating gauge pressure p₍g₎ (bar(g))

bar

Piston bore / cylinder inside diameter

Piston-rod diameter

Stroke

Double strokes per minute

1/min

Force efficiency

Dead volume per chamber

cm³

Required extension force (optional)

Results

Complete the inputs and calculate.

Model

Force = gauge pressure × effective piston area × efficiency. Air quantities are reported as free air at 1.01325 bar(a) and 20 °C.

Scope

Results are preliminary engineering estimates. Manufacturer curves, loads, temperature, leakage, cushioning, and the complete safety and pressure-equipment assessment remain separate.

Standards

ISO 1219-1 and ISO 6358-1 provide symbols, terminology, and test-method context; ISO 4414 is used as a safety context. No standards compliance is certified.
