Why is it best to install a cylinder with the ports at the top?

Installing a hydraulic cylinder with the ports at the top is primarily beneficial for bleeding air out after installation. When hydraulic systems are filled with fluid, any trapped air can interfere with proper operation and efficiency. By placing the ports at the top, air can easily escape since it naturally rises to the highest point in the system. This ensures that the cylinder operates efficiently and avoids potential issues such as cavitation or reduced performance caused by air pockets in the hydraulic fluid.

While there may be considerations for aesthetics, maintenance, or fluid flow, the foremost advantage of this configuration lies in the ability to effectively remove air. Maintaining a fluid system that is free of air is crucial for ensuring reliable operation and longevity of the components involved.
