Pneumatic cylinders continue to provide a valuable and preferred option for linear actuation in many applications. To achieve these unprecedented levels of effectiveness, all portions of the cylinder design must be balanced to reach the desired performance and cost ratio.
As you can see from the cutaway cylinder in Figure 1, pneumatic cylinders have a large number engineered components working together. One of the critical areas of engineering required for achieving this performance is good sealing system design. To achieve the necessary sealing system effectiveness, engineers for a variety of components involved in a pneumatic cylinder need to work together to reach the right balance for each application. Looking at the output of linear actuator is a great place to start to begin to understand the factors to be balanced for an effective linear actuator.
