Motion control systems that require linear movement can be designed with a variety of different technologies. The most commonly used can be grouped into three categories: linear actuators, linear motors and precision positioning tables. Linear actuators solve a wide range of applications and are generally the lowest cost solution. They can be hydraulic, pneumatic or electromechanical, each with advantages and drawbacks that depend upon the application.
Hydraulic and pneumatic limitations
Hydraulic cylinders, for example, are used for handling extremely high loads. While they have force capabilities as high as several tons, hydraulic systems have a ...
