The hydraulic cylinder is a device for converting a medium's pressure energy, for example hydraulic oil, into a linear drive motion. A hydraulic cylinder consists of a cylinder tube in which a piston rod with a piston moves back and forth.

A hydraulic cylinder is a hydraulic actuator that provides linear motion when hydraulic energy is converted into mechanical movement. It can be likened to a muscle in that, when the hydraulic system of a machine is activated, the cylinder is responsible for providing the motion.

In conclusion, the key benefits of hydraulic cylinders are their ability to provide a significant amount of linear force, efficient power-to-weight ratios, variable speed control, and the ability to provide power to machines in even the furthest locations away from the power generation source.
