A hydraulic cylinder is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke12. It is also called a linear hydraulic motor1. Hydraulic cylinders are used in many products because they can transform a small force into a large force2. They contain a piston, and the piston is moved by injecting oil into the cylinder through a valve or by suctioning oil from the cylinder2. Hydraulic cylinders have many applications, notably in construction equipment, manufacturing machinery, and civil engineering1.
