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 so are available in a number of configurations. Both primary types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can possess unique applications due to their styles. Tie-rod cylinders are often set up in light to moderate duty applications and are generally designed to become repaired or re-packed if necessary. Welded cylinders are created for most applications and are more technical in design but are usually more difficult to correct because of the welded design. Welded cylinders are typically a better solution due to their compact design and when a more robust style is hydraulic cylinder china important in an application.
