Choosing Between Electromechanical and Fluid Power Linear Actuators in Industrial Systems Design (letter)

Linear actuation plays a critical role in a wide range of products and processes in factory automation, packaging, medical devices, and many other fields. Linear actuators are commonly divided into two main types: fluid power actuators that operate on differential pressure and electromechanical actuators driven by an electric motor. The type of actuator used plays a critical role in the machine’s performance, initial cost and operating costs. This article will look at the pros and cons of each of the main types of linear actuators with the goal of providing a general guide for their selection and application.
