Linear Actuators

Linear actuator

Linear refers to the motion of going in a straight line which can either be side to side or up and down. This act of motion is created by a hydraulic or pneumatic cylinder. Linear actuators create a straight line of motion in contrast to the motion a motor uses.

What Is A Linear Actuator?

There are many different kinds of actuators. Hydraulic actuators usually have a hollowed out piece in which a piston will fit. The piston uses force to move external objects. Pneumatic actuators use compressed air to create motion. It lets out air in the chamber and then forces it out the other side. It can pull and push the motion in either direction. Linear actuators are used similarly to that of a motor, except in a motor the motion is circular. There are many different types of linear actuators including mechanical linear actuators. Mechanical linear actuators work by the act of pulling or pushing. They convert motion through a few different methods including screw, wheel, axle and cam actuators. Some linear actuators use a rod to function properly. Each type of linear actuator has it’s own set of advantages and disadvantages. Linear actuators may use screws including acme or ball screws. There are many different types of motors used in linear actuators including DC, AC and stepper motors.

What Industries Use Linear Actuators?

Linear actuators are used in many different industries and products. Linear actuators can be used in commercial grade products and household items as well. The type of linear actuator that gets selected depends on many different aspects including the length, width and height. Other important considerations include the weight it will have to support, stroke positions, brakes and possible backlash. Linear actuators are often used in heavy machinery because they can act like a motor. Linear actuators are also used in tools, computer equipment and electronics.

Benefits

Linear actuators make straight motion possible for creating force. Linear actuators include many new features which will help to increase safety and function. Some of the new features include being water-resistant, thermal overload protection and cushion absorbing ends.
