A hydraulic cylinder is a mechanical actuator used to supply unidirectional force through a unidirectional stroke. Hydraulic cylinders are used in almost every market and are available in a variety of configurations. The two primary types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can have unique applications because of their styles. Tie-rod cylinders are often installed in light to moderate duty applications and tend to be designed to be repaired or re-packed if required. Welded cylinders are made for most applications and are more technical in design but are usually more difficult to repair because of the welded design. Welded cylinders are typically a better solution due to their compact design so when a more robust design is important in an application.
