Hydraulic cylinders are used as linear actuators to apply unidirectional force and stroke in many Engineering applications. Hydraulic cylinders are used to create mechanical force in a linear motion. They are used to lift something, push something, press something, and many other types of work.

A single acting hydraulic cylinder, also known as a single acting hydraulic ram, operates in a single direction. It typically has a single port at the bottom of the cylinder where pressurised fluid is pumped into the system. As the fluid enters the system, it fills the cylinder and extends the piston inside.
To retract the piston, a single acting hydraulic cylinder must rely on an external force to expunge the fluid inside. This can be left to gravity if there is no immediate need to retract the piston, but a second piston can also be used to forcefully push the piston back into the cylinder. Springs can also be used if they are strong enough.
