4. General purpose

It's obvious that a vertical cylinder with no side load, exiting upwards at low speed (the body acts as a settling tank) in a clean atmosphere, will have lower wear than a cylinder placed in severe operating conditions. We can therefore deduce that the best use of a cylinder will be obtained for an optimal layout, with reduced forces on the guides, the absence of clamping forces from joints without sufficient freedom at no load and under load, suitable filtration and sufficient maintenance of the cylinder itself and its joints so that they pivot without requiring abnormal torque.

Filtration of hydraulic circuits of recent design is becoming widespread, at around 30 µm. While this is an improvement on the still recent past, it is still far from sufficient to ensure long-lasting service for moving parts. If we consider that cylinders often spend their life at a standstill,...
