A hydraulic cylinder is a mechanical actuator used to supply unidirectional force through a unidirectional stroke. Hydraulic cylinders are used in almost every industry and are available in a variety of configurations. Both primary 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 often set up in light to medium duty applications and are generally designed to end up being repaired or re-loaded if required. Welded cylinders are designed for most applications and so are more technical in design but are generally more difficult to correct because of the welded design. Welded cylinders are usually a better solution due to their compact design so when a more robust design is hydraulic cylinder china important within an application.
