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 are available in a hydraulic cylinder china number of configurations. Both primary types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can possess unique applications because of their designs. Tie-rod cylinders are often set up in light to medium 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 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 important within an application.
