A hydraulic cylinder is a mechanical actuator used to provide unidirectional force through a unidirectional stroke. Hydraulic cylinders are used in almost every market 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 because of their styles. Tie-rod cylinders are often installed in light to moderate duty applications and are generally designed to be repaired or re-packed if necessary. Hyd Cylinder Welded cylinders are designed for most applications and are more technical in design but are generally more difficult to repair due to the welded style. Welded cylinders are usually a better solution due to their compact design and when a more robust design is important in an application.
