What is Tie Rod Cylinder
Tie rod cylinders are another cylinder variety. They have threaded tie bolts or rods that extend the length of the cylinder tube, passing through holes in the cylinder end caps. The rods are held in place with a nut to secure the end caps to the cylinder barrel. How many threaded tie bolts there are depend on the diameter of the bore in addition to the operating pressure, but the number ranges from 4 to 20.
Features of Tie Rod Cylinder
Unmatched Strength and Durability
The tie-rod design distributes stress evenly across the cylinder, allowing it to withstand the high pressures and heavy loads commonly encountered in construction projects.
Versatility
From excavators and bulldozers to cranes and loaders, these cylinders can be customized to meet the specific requirements of each machine. This adaptability allows construction professionals to optimize their equipment’s performance and efficiency.
Simplified Maintenance and Repair
The tie-rod assembly allows for easy disassembly and reassembly, enabling technicians to quickly access internal components for inspection, cleaning, or replacement. This simplified maintenance reduces downtime and helps minimize repair costs.
Customizable Mounting Options
This flexibility in mounting configurations allows for optimal integration into construction equipment, ensuring that the cylinder operates effectively and efficiently. By selecting the appropriate mounting option for each application, construction professionals can maximize the performance of their hydraulic systems.
Better Safety Features
Tie-rod hydraulic cylinders have load-holding valves and pilot-operated check valves. These components help prevent unintentional cylinder movement and minimize the risk of injuries. By investing in tie-rod hydraulic cylinders with advanced safety features, construction companies can maintain a safer work environment.

Standard-Duty Tie Rod Cylinders
Used in industrial actuators rated to 2,500 psi, standard-duty tie rod cylinders are easy to repair as their standardized dimensions allow the convenient interchange of components from different manufacturers with the same mountings.
Heavy-Duty Tie Rod Cylinders
These cylinders can be used in hydraulic systems up to 5,000 psi due to their thicker body walls and larger rod diameters. Their additional strength and rigidity are designed to withstand heavy-duty work environments.
Parts of Tie Rod Cylinder
The barrel is designed to contain the pressure of the cylinder. This barrel is made from honed tubes which are made from Cold Drawn Seamless Tubes. This steel has to be suitable to be honed. Honing is an abrasive machining process used to produce a precision and smooth surface on the metal that is being honed. Honing is one of the main processes to manufacture a hydraulic cylinder tube. The inside surface of the tube should have a smooth inside surface, be durable and have a high precision tolerance.
The cylinder head, also known as the “blind end”. This part is inside the cylinder barrel and is not exposed to daylight, hence the name. This part encloses the pressure chamber from one end of the cylinder. The cylinder head has the option for an integrated rod sealing arrangement or an option for a seal gland which we will discuss in this article in detail.
This part encloses the pressure from the other end of the cylinder barrel. This part is also referred to as the rod end. This can be identified by an opening where the cylinder rod connects to.
The piston inside the hydraulic cylinder is used to separate the pressure zones inside the barrel. The piston is machined to fit rubber or metallic seals which can be single-acting or double-acting. The piston rod is attached through threads, bolts or nuts to transfer the linear motion. Depending on where pressure is applied on either side of the piston will cause the hydraulic cylinder to extend or retract.
Also known as the cylinder rod. This is made from hard chrome plated cold rolled steel. The rod is attached to the piston and the cylinder head. The piston rod connects the hydraulic cylinder to the machine component that is used to do work. The piston rod is made from hard chrome for its properties to be grounded and polished very well. This ensures a reliable seal which prevents leaks.
The hydraulic cylinder gland is fitted with a number of seals that prevent the pressured oil from leaking past the interface of the cylinder rod and the cylinder head. If you take the option of the seal gland this will give you the advantage of easy removal and replacement of all the seals needed to prevent leaks. The seals within the seal gland are the primary seal, secondary seal, wear bands, wiper, scrapper and the static seal.
The seals used within the seal gland are made specifically according to the cylinder working pressure, speed of the cylinder, operating temperature and the application of the hydraulic cylinder. These are dynamic seals and can be single-acting or double-acting. Hydraulic cylinders used in lower temperature environments use Elastomer seals made from nitrile rubber.
How to Choose Tie Rod Cylinder
Operating Pressure
It is essential to give more attention to the operating pressure of the tie rod cylinder. This refers to the maximum pressure the cylinder can handle without risking and undergoing any damage or malfunction. Ensure that the cylinder’s operating pressure matches or exceeds the requirements of your vehicle’s steering system to ensure better performance and safety.
Stroke Length
The stroke length of the tie rod cylinder is one of the essential parameters, defined as the distance the piston can travel within the barrel. The appropriate stroke length is necessary for achieving the desired steering response and manoeuvrability. Consider factors such as vehicle weight, turning radius, and steering geometry to determine the ideal stroke length for your application.
Seal Type
Selecting the proper seals for a tie rod cylinder can significantly affect its overall reliability and longevity. High-quality seals are needed for daily driving to prevent hydraulic fluid leakage. The most commonly used seal materials are rubber, polyurethane, and Viton, each offering varying levels of durability and resistance to heat and chemicals. Ultimately, the choice of the correct seal material will depend on the tie rod cylinder’s specific requirements.
Mounting Configuration
These cylinders come in various mounting configurations, such as trunnion mount, clevis mount, and cross-tube mount. Consider space and accessibility when choosing a mounting configuration. A properly configured mounting system will provide secure attachment points, seamless integration, and reliable performance.
Material And Construction
Tie rod cylinder durability relies on material and construction. Opt for cylinders constructed from high-quality materials such as steel or aluminium, which offer excellent strength and corrosion resistance. Additionally, rod diameter and barrel thickness should be considered to ensure robustness and longevity.
Installation And Maintenance
Follow the manufacturer’s guidelines and recommendations for installation, ensuring proper alignment and torque specifications are met. Additionally, adhere to regular maintenance intervals, such as inspecting seals for wear, checking fluid levels, and lubricating moving components.
