Hydraulic Cylinders, Rotary Actuators & Motors

Hydraulic Actuators

Hydraulic Actuators convert the energy of pressurized fluid into useful motion which can be transferred to a working linkage, platen, slide or other mechanical device to do the actual work required. Actuators are divided into three (3) basic types:

Cylinders
Convert this energy into straight line or linear motion. These can be used to move, position, compress or lift a load. They can be used in conjunction with lever arms, toggle elements or other mechanical components to describe a specific motion such as an arc.

Rotary Actuators
Convert this energy into a discrete rotary motion. That is, they can permit motion around an axis. This is particular useful in applications requiring reciprocating rotary motion, where a part must be rotated up to 180° or more, and then returned to it's original starting position.

Motors
Convert this energy into continuous rotary motion, much like an electric motor, but with the added benefit that their speed, output force and direction of rotation can be controlled using simple valves. Also, unlike electric motors, they can be stalled without harmful consequences.
