HomeCalculatorsHydraulic Cylinder Velocity

Hydraulic Cylinder Velocity

v = Q / A - extend / retract velocity from pump flow and cylinder area.

Hydraulics
Extend velocity
0.050m/s
Retract velocity
0.073m/s

Formula, assumptions, and limits

$$v = \frac{Q}{A}$$

Retract stroke is faster because of reduced area on the rod side. Return-flow to tank from retract = $Q_{\text{ret}}$ · $A_{\text{ext}}$ / $A_{\text{ret}}$, which can exceed pump flow - size return filters accordingly.
