A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic cylinders are found in almost every sector and are available in a variety of configurations. Both main types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can possess unique applications because of their designs. Tie-rod cylinders are usually installed in light to medium duty applications and tend to be designed to end up being repaired or re-packed if required. Welded cylinders are made for most applications and so are more complex in design but are usually more difficult to repair due to the welded design. Welded cylinders are usually a better solution because of their compact design so when a more robust style is important within an application.
