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