Hydraulic cylinders are hydraulic actuators that generate linear motion by utilizing the pressure of hydraulic fluid supplied from hydraulic pumps. In manufacturing, they are widely used for lifting, lowering, and clamping heavy objects in press machines, injection molding machines, construction machinery, and machine tools. Available in single-acting and double-acting types, various specifications can be selected based on stroke length, bore diameter, and operating pressure. Capable of high thrust and precise positioning, they are also employed in industrial robot arm drives and conveyor systems in automated production lines.
