A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic cylinders are used in almost every industry and are available in a number of configurations. The two main types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can have unique applications because of their styles. Tie-rod cylinders are usually installed in light to moderate duty applications and are generally designed to become repaired or re-loaded if necessary. Welded cylinders are designed for most applications and are more complex in design 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 in an application.
