Linear Actuators: ALIO Industries

Linear Actuators are actuators that create motion in a straight line, as opposed  to the circular motion of a conventional electric motor. Linear actuators can be used in machine tools and industrial machinery, in computer peripherals (disk drives and printers), in valves and dampers, and in many other applications where linear motion is required.

Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor.

A linear actuators is a piece of equipment that turns rotational motion into linear motion, through the application of linear force. This happens because a linear motor is modified in such a way as to only move in linear directions rather than rotational ones.

Types of Linear Actuators

Hydraulic actuators:

These have a hollow cylinder for the moving piston, and works by applying unequal pressure to the piston in order to move it in the direction needed.

Mechanical actuators:

Mechanical actuators convert energy through a number of means, be that wheel and axle, screw, or cam. They are notable for quite often being one-way actuators.

Magnetic actuators:

These actuators use a magnetic force to convert the electric current provided by the motor into linear motion. This magnetic force can be used to create different force strokes and movements in the actuators.

Pneumatic actuators:

Pneumatic actuators function in almost the same way as hydraulic actuators except that the gears and cylinder are controlled using compressed air to control when they move and when they stop.

Electric actuators:

An electric actuator is specifically designed to have fewer working parts than other actuators, cutting down on both maintenance and the difficulty of operating it. These actuators run directly on a current, and are therefore not able to be hand-operated, although they can sometimes be slaved to a remote control, if the user wants to be able to control them remotely.
