A hydraulic cylinder is a mechanical actuator used to supply unidirectional force through a unidirectional stroke. Hydraulic cylinders are found in almost every market and are available in a number of configurations. The two hydraulic cylinder china 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 so are more technical in style but are generally more difficult to correct because of the welded design. Welded cylinders are typically a better solution due to their compact design so when a more robust design is important in an application.
