1 — Cylinder Geometry

ISO 15552 Preset Bore D

Rod d

Friction loss (%)

Cap-side area: — mm² Rod-side area: — mm² Area ratio: —

2 — Force Calculator

Cap-side Pₐ

Rod-side Pᵇ

Direction

Extension Retraction

—

F = Pₐ·A_cap − Pᵇ·A_rod (extension). Effective = theoretical × (1 − friction%).

3 — Required Pressure

Target force

Cap-side Pₐ

Rod-side Pᵇ

Direction

Extension Retraction

—

Fill in the target force and one known pressure. The calculator solves for the missing one. Friction is applied to the target force.

4 — Bore Sizing

Target force

Available pressure

Direction

Extension Retraction

—

Calculates minimum bore for the target force. For retraction, uses standard ISO rod sizes. Suggests next ISO 15552 bore.

5 — Air Consumption

Stroke

Cycles / min Supply pressure

—

Free air per double stroke (extend + retract) using Boyle's law. Atmospheric pressure = 1.01325 bar.
