Double acting hydraulic cylinder is a type of actuator that uses hydraulic pressure to produce force in both extension and retraction strokes. It features two ports—one for fluid to enter and extend the piston, and another for fluid to enter and retract it—allowing for precise bidirectional control. This design provides consistent power in both directions and is ideal for applications requiring push-and-pull motion, such as in construction machinery, industrial presses, and mobile equipment. Double acting cylinders offer greater versatility and efficiency compared to single acting types, making them suitable for more demanding and dynamic hydraulic systems.
