Linear actuators are simple electromechanical devices that turn electrical power into linear motion instead of rotational actuators. Linear actuators tend to be more compact, accurate, and reliable than rotary actuators, making them the ideal solution for many applications that involve linear motion. Linear actuators also have the distinct advantage of requiring fewer gears or other components to convert rotary motion into the desired amount of linear motion. For example, some jackscrews need several gears to generate one inch of linear motion. Linear actuators need only two or three components at most. Linear actuators can turn a simple push or pull into an arc that'll extend as far as your arm will allow. In fact, the versatility and simplicity of linear actuators make them a favorite among industry professionals.
