Heavy duty Hydraulic Cylinder

Piston Rod: This is the moving part that is pushed out or retracted as the piston moves.

Piston: The piston is located in the cylinder and moves back and forth as hydraulic fluid is pumped into the cylinder.

Tie Rods: Typically made of steel, tie rods extend along the outside length of the cylinder barrel and are used to secure the end caps to the barrel.

End caps: These end caps are mounted on the ends of the cylinder barrel and enclose the hydraulic fluid within the barrel.

Seals: Seals are used throughout the hydraulic cylinder to prevent fluid leakage and maintain pressure.

Piston Rod Seal: This is the part of the cylinder head or cap where the piston rod protrudes from the cylinder.

Ports: Hydraulic fluid enters and exits the cylinder through these ports, usually located on the end caps.


Tie rod heavy duty hydraulic cylinders operate by the movement of hydraulic fluid to provide controlled, powerful motion. Tie rods secure the end caps to the cylinder barrel, giving structural integrity and durability. This design allows for easy disassembly and reassembly for maintenance and repair. Typically made of steel, these tie rods are critical to maintaining the structural integrity of the cylinder.

Designed to operate efficiently over a wide range of pressures, these cylinders are suitable for a variety of heavy-duty tasks. The stroke length of these cylinders can be customized to meet specific operational requirements, making them even more versatile.


Robustness: The structural integrity provided by tie rods ensures durability and longevity.

Ease of Maintenance: Tie rod construction allows for easy disassembly, facilitating repairs and reducing downtime.

Versatility: These cylinders can be customized in terms of stroke length and bore size, making them suitable for a wide range of applications.

High Pressure Tolerance: They are capable of operating efficiently under high pressure, making them ideal for heavy-duty tasks.

Precision Control: Offers accurate and controlled movement, which is crucial in many industrial applications.


Manufacturing Machinery: Commonly used in presses, injection molding machines, and other manufacturing equipment where precision and strength are key.

Construction Equipment: Employed in cranes, bulldozers, and excavators for lifting and moving heavy loads.

Agricultural Machinery: Used in tractors and harvesting machines for various farming operations.

Material Handling: Essential in conveyor systems, forklifts, and pallet jacks for efficient movement of goods.

Automotive Industry: In manufacturing and assembly lines for tasks like lifting and positioning.

Tie Rod Heavy Duty Hydraulic Cylinder

During a pressure test, each hydraulic cylinder is rigorously evaluated under controlled conditions. Cylinders are subjected to pressures beyond their normal operating range, typically up to 1.5 times their maximum rated pressure. The test is designed to identify any weaknesses in the cylinder, such as leaks or deformation. The focus is to ensure that all components, especially the tie rods, maintain their integrity under high pressure. In addition, the test evaluates cylinder performance, such as response to pressure changes and smoothness of piston movement.

Ensuring that every tie rod heavy-duty hydraulic cylinder passes the pressure test is critical to maintaining our high standards of quality and safety. This commitment to excellence ensures that our hydraulic cylinders are not only robust and durable, but can be used in a wide range of demanding industrial applications.
