A linear actuator is a type of actuator that is responsible for creating motion along a straight line, in contrast to the circular motion of an electric motor. Linear actuators are commonly used in industrial settings, such as in machinery and tools. They are also found in computer peripherals like disk drives and printers. However, this technology is crucial in many different applications and environments. For example, one type of linear actuator, the subsea actuator, is specially designed to operate in depths of up to 22,000 feet underwater and 10,000 psi.
