Hydraulic Linear Actuator Design Considerations

While there are many types of Linear Actuators ranging from the simple “roller screw” model to sophisticated electro-mechanical, pneumatic, piezoelectric, and hydraulic, a linear actuator generally refers to devices that convert rectilinear or electro-rotational motion into linear motion.  Hydraulic linear actuators refer to those classes of devices where an unbalanced fluid pressure applied to the piston can generate a large force that can move an external object.  While gas cylinders are useful in certain
