A hydraulic cylinder is a mechanical actuator that converts hydraulic pressure into linear force and motion. Pressurized hydraulic oil moves the piston inside the cylinder barrel, resulting in controlled extension and retraction of the piston rod. Hydraulic cylinders are used for lifting, pushing, pulling, pressing, and tilting applications in industrial and mobile equipment. They provide high force output, precise movement, smooth operation, reliability, and efficient performance in demanding applications such as construction machinery, cement plants, mining equipment, hydraulic presses, and material handling systems.
