Knowra Hydraulic cylinder Hydraulic cylinder A mechanical actuator that converts hydraulic pressure into linear force and motion. Its piston moves inside a cylinder as pressurized fluid enters one or both sides.
Pascal's law : Pressure applied to a confined fluid is transmitted throughout the fluid and to its container walls. It explains how pressure in the cylinder fluid acts across the piston.
Single-acting cylinder : A hydraulic cylinder powered by fluid pressure in one direction, with return motion supplied by a spring, load, or external force. It is the simplest cylinder arrangement, with powered motion in only one direction.
Hydraulic press : A machine that uses hydraulic pressure to apply a large compressive force to a workpiece. A cylinder provides the pressing force and travel.
Pneumatic cylinder : A linear actuator powered by compressed gas, usually air. It resembles a hydraulic cylinder but uses compressible gas and typically lower forces.
Piston : A movable component that separates regions inside a cylinder and transfers force through its motion. Hydraulic pressure acts on its area to create the cylinder's linear force.
Double-acting cylinder : A hydraulic cylinder that uses fluid pressure alternately on both sides of its piston for powered extension and retraction. Its two pressure ports allow powered motion in both directions.
Hydraulic excavator : A tracked or wheeled machine that uses hydraulic systems to dig, lift, and move material. Its boom, arm, and bucket movements are driven by cylinders.
Electric linear actuator : A device that produces straight-line motion using an electric motor and a mechanical transmission. It can replace a hydraulic cylinder where electrical control and simpler fluid-free installation matter.
Hydraulic seal : A component that limits fluid leakage between moving or stationary surfaces in a hydraulic system. The piston seal prevents high-pressure fluid from bypassing the piston.
Cylinder barrel : The hollow pressure-containing tube in which a hydraulic cylinder's piston travels. Its bore and strength constrain piston size, pressure, and stroke.
