Structurally, it is mainly composed of cylinder barrel, piston, piston rod, front and rear end caps, and tie rods. The tie rod connects the front and rear end caps with the cylinder barrel, playing the role of fixing and strengthening the structure. The cylinder barrel is usually made of high strength steel, and the interior is precision machined to ensure the smooth movement of the piston. The piston is connected to the piston rod to convert hydraulic energy into mechanical energy and realize linear motion.

The working principle is that the pressure of hydraulic oil acts on the piston, pushing the piston to move in the cylinder barrel, thus driving the piston rod to extend or retract. When the hydraulic oil enters the rodless chamber of the cylinder, the piston rod extends; when the hydraulic oil enters the rod chamber, the piston rod retracts.

Tie rod cylinder has many advantages. It has a simple structure, easy installation and relatively low cost. Due to the fixed role of the tie rod, the cylinder has good stability and reliability. At the same time, the sealing performance of the tie rod cylinder is better, which can effectively prevent hydraulic oil leakage. It is widely used in a variety of mechanical equipment, such as engineering machinery, machine tools, injection molding machines, etc., to achieve linear motion drive and control.
