Ideal force, speed, and time screen
Hydraulic cylinder
Inputs
Stated inside bore diameter for a double-acting cylinder.
Stated rod diameter; it must be smaller than the bore.
Uniform fluid pressure at the actuator, not a pressure-rating check.
One full linear travel used only for ideal swept volume and travel-time arithmetic.
Steady delivered flow; this screen does not model a circuit or losses.

Method
Formula, when it applies, and when it does not
Calculate ideal extension/retraction area, force, volume, speed, and travel time for one double-acting cylinder from dimensions, pressure, and flow.
Ap = πD²/4; Aa = Ap−πd²/4; F = pA; V = As; v = Q/A; t = s/v
When
- Double-acting cylinder
- Steady incompressible flow
- Uniform pressure
- No mechanical loss
Don’t
- This is ideal double-acting cylinder arithmetic using declared pressure and steady delivered flow. It excludes pressure drops, friction/seal losses, side loading, rod buckling, cushioning, compressibility, valve dynamics, acceleration, mounting, structural loads, duty cycle, temperature, component ratings, and circuit or safety design.
