Working Principle
Extension
Pressure is applied to the fluid port. The largest-diameter stage (the barrel or first stage) extends first, followed by the successively smaller stages, each pushing outward from the previous one. As each stage extends, the piston area reduces, leading to a corresponding decrease in output force.
Retraction
Pressure is applied to the rod-side port. The smallest stage (the innermost) retracts first, followed by the larger stages. This requires precise porting and pressure management for smooth operation.
Key Design Features and Types
Single-Acting vs. Double-Acting
Single-Acting:Retraction relies on the load’s gravity or an external spring, commonly used in lifting applications.
Double-Acting:Extension and retraction are both controlled by hydraulic or pneumatic pressure, providing more precise control.
Number of Stages
Typically has 2 to 6 stages, determined by the application’s stroke length and space constraints.
Force Decay
Output thrust decreases as each stage extends due to reduced effective piston area. This is a critical calculation factor during cylinder selection.
