A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic cylinders are found in almost every sector and so are available in a variety of configurations. The two main types of hydraulic cylinders are Tie-rod and Welded. Each of these cylinder types can have unique applications due to their designs. Tie-rod cylinders are usually set up in light to medium duty applications and are generally designed to become repaired or re-packed if necessary. Welded cylinders are designed for most applications and so are more complex in style but are usually more difficult to repair due to the welded style. Welded cylinders are typically a better 
solution due to their compact design and when a more robust style is important in an application.
