Hydraulic cylinder
open-in-new
<p>A hydraulic cylinder (also called a linear <a href="/facts/Hydraulic_motor/vvF2RMGs">hydraulic motor</a>) is a mechanical <a href="/facts/Actuator/mF9qVJJR">actuator</a> that is used to give a unidirectional <a href="/facts/Force/533Q1uzq">force</a> through a unidirectional stroke. It has many applications, notably in construction equipment (<a href="/facts/Engineering_vehicles/e2uMkvnK">engineering vehicles</a>), <a href="/facts/Manufacturing_machinery/XPHaqz0p">manufacturing machinery</a>, <a href="/facts/Elevator/ug3nh0o8">elevators</a>, and <a href="/facts/Civil_engineering/avh5kEq2">civil engineering</a>. A hydraulic cylinder is a hydraulic actuator that provides <a href="/facts/Linear_motion/Vom0QwWe">linear motion</a> 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. </p>
