A hydraulic cylinder is a mechanical actuator used to supply unidirectional force Hyd Cylinder china through a unidirectional stroke. Hydraulic cylinders are found in almost every industry and are available in a variety of configurations. Both main types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can have unique applications because of their designs. Tie-rod cylinders are usually 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 made for most applications and so are more technical in style but are generally more difficult to correct because of the welded style. Welded cylinders are usually a better solution because of their compact design so when a more robust design is important within an application.
