Hydraulic Actuator

Hydraulics Online: Hydraulic actuator and equipment supplier. Major brands, direct equivalents, innovative systems design and repairs. You name it. We do it.

A hydraulic actuator is a hydraulic cylinder or hydraulic motor that converts hydraulic power into useful mechanical work; the mechanical motion produced may be linear, rotary, or oscillatory.

A linear actuator is an actuator that creates motion in a straight line, as contrasted with circular motion of a conventional electric motor. Hydraulic cylinders inherently produce linear motion; many other mechanisms are used to provide a linear motion from a rotating motor.

A hydraulic actuator or hydraulic cylinder typically involves a hollow cylinder having a piston inserted in it. An unbalanced pressure applied to the piston provides force that can move an external object. Since liquids are nearly incompressible, a hydraulic cylinder can provide controlled precise linear displacement of the piston. The displacement is only along the axis of the piston. A familiar example of a manually operated hydraulic actuator is a hydraulic car jack. Typically though, the term "hydraulic actuator" refers to a device controlled by a hydraulic pump. A hydraulic actuator can also be designed to fail-open or fail-close to prove a fail-safe feature.
