Working Principle
Extension
Pressure is applied to the fluid port. The largest-diameter stage (the barrel or first stage) extends first, followed in sequence by the successively smaller stages, each pushing outward from the inside of the previous one. As each stage extends, the piston area diminishes, which leads to a corresponding reduction in the available output force.
Retraction
Pressure is applied to the rod-side port. The smallest stage (the innermost stage) retracts first, with the larger stages following in sequence. This process demands precise porting and pressure management to ensure smooth operation.

Key Design Features and Types
Single-Acting vs. Double-Acting
Single-Acting: It usually retracts by relying on the load’s gravity or external spring force and is commonly used in lifting applications.
Double-Acting: Both extension and retraction are controlled by hydraulic or pneumatic pressure, delivering more precise operational control.

Number of Stages
Typically, it has 2 to 6 stages, with the specific count determined by stroke length and space constraints of the application.

Force Decay
The output thrust decreases as each stage extends, due to the reduction in the effective piston area. This is a critical calculation factor during the cylinder selection process.
