Engineers who understand and can take advantage of the differences between fluid power and electromechanical power can build machines that produce higher quality output with lower lifecycle costs, particularly in applications where precise control of large forces and smooth motion are required. The key to unlocking the benefits of hydraulic power is understanding the system requirements, selecting and sizing hydraulic system elements appropriately and tuning the motion controller for optimal performance. The most common use of hydraulic power is linear motion and the major components of a typical linear system are shown in Figure 1.
