A hydraulic cylinder is controlled by directing flow to the correct chamber, metering flow for speed and managing pressure and load energy with properly selected valves. The cylinder, pump, directional valve, flow control, load-control valve and machine structure must be designed as one system.

A hydraulic cylinder bench should be designed as a restrained service fixture, not as a general-purpose table. It must support the barrel and rod without crushing them, control rotation, contain components during disassembly and keep personnel out of the line of fire.

A dump truck uses a hydraulic cylinder because a cylinder converts fluid pressure into controlled linear force that can rotate the body about its rear hinge. The hoist geometry multiplies and redirects that force, while the hydraulic circuit controls raising, holding and lowering.

Two hydraulic cylinders do not remain synchronized merely because they share a pump line. Small differences in load, friction, leakage, geometry and hose p

A telescopic hydraulic cylinder uses several nested tubular stages to produce a long stroke from a comparatively short retracted package. Pressurized oil n

A single-acting hydraulic cylinder uses pressurized oil to move in one direction. It returns through gravity, a spring or an external machine force, so the

A hydraulic displacement cylinder produces linear motion by directing pressurized fluid into a chamber where the moving member itself displaces fluid. In a

Rephasing hydraulic cylinders are matched cylinders used in a series circuit so several sections of a machine can move in sequence at approximately the sam

Surplus hydraulic cylinders and pneumatic actuators are commonly purchased by industrial surplus dealers, equipment rebuilders, repair shops, parts reselle

A pneumatic cylinder should not be used as a hydraulic cylinder unless the manufacturer has explicitly rated that exact design for hydraulic fluid
