Most hydraulic systems will operate satisfactorily using a variety of fluids. These include engine oil, automatic transmission fluid and oil formulated specifically for the hydraulic compartment. But which type of fluid is best for a particular application?

Where does hydraulic fluid enter and exit a cylinder?

The neck gland material would be chosen during design, with seals on both the rod and the tube. Hydraulic fluid needs to enter and exit the cylinder via ports, with one port at either end of the cylinder tube and the hydraulic piston between the two ports.

How does a single acting cylinder accept pressurized fluid?

Single-acting cylinders, Figure 2, accept pressurized fluid on only one side of the piston; volume on the other side of the piston is vented to atmosphere or returns to tank. Depending on whether it is routed to the cap end or rod end, the pressurized fluid may extend or retract the cylinder, respectively.

What should be specified in a hydraulic cylinder?

There are subordinate functions to be considered when specifying a hydraulic cylinder, such fluid type, column strength and material construction. However, 90% of cylinder applications are not exotic, and simply identifying force and mounting requirements will suffice, leaving all else standard.
