What Is the Pneumatic Cylinder Thrust & Air Consumption Calculator?
Pneumatic cylinders convert the potential energy of compressed air into linear mechanical force and motion.
Thrust force is governed directly by piston surface area multiplied by pneumatic pressure.
How Does the Pneumatic Cylinder Thrust & Air Consumption Calculator Work?
Computes extension piston area and rod-annulus retraction area.
Multiplies area by pressure to calculate thrust in pounds and Newtons.
Calculates compressed air volume and normalizes to standard atmospheric SCFM.
Pneumatic Cylinder Thrust & Air Consumption Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Extension force acts on the full piston face; retraction force is reduced by the cross-sectional area of the piston rod.
How to Use the Pneumatic Cylinder Thrust & Air Consumption Calculator
- Enter bore diameter, rod diameter, and stroke length in inches.
