A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic Hyd Cylinder cylinders are found in almost every market and are available in a number of configurations. The two primary types of hydraulic cylinders are Tie-rod and Welded. Each one of these cylinder types can have unique applications because of their designs. Tie-rod cylinders are often installed in light to medium duty applications and tend to be designed to be repaired or re-loaded if necessary. Welded cylinders are created for most applications and so are more technical in design but are usually more difficult to repair because of the welded style. Welded cylinders are usually a better solution due to their compact design and when a more robust design is important within an application.
