A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic hydraulic cylinder china cylinders are used in almost every market and so are available in a number of configurations. The two primary types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can possess unique applications due to their designs. Tie-rod cylinders are often set up in light to moderate duty applications and are generally designed to be repaired or re-packed if necessary. Welded cylinders are designed 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 and when a more robust style is important in an application.
