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. Both main types of hydraulic cylinders are Tie-rod and Welded. Each one of these cylinder types can have unique applications due to their designs. Tie-rod cylinders are usually set up in light to moderate duty applications and are generally designed to be repaired or re-packed if required. Welded cylinders are made for most applications and are more complex in style but are generally more difficult to repair because of the welded design. Welded cylinders are usually a better solution because of their compact design so when a more robust style is important within an application.
