In modern hydraulic systems, the tie-rod hydraulic piston rod (MOB Series) plays a crucial role. As one of the core components of a hydraulic cylinder, it not only transmits power but also impacts the overall performance and reliability of the system.
The tie-rod hydraulic piston rod (MOB Series) is a hydraulic cylinder piston rod assembly with a tie-rod connection design. The front and rear covers of this type of cylinder are connected by four tie-rods, hence the name tie-rod cylinder or four-tie-rod cylinder. Due to its often square shape, it is also called a square cylinder. The MOB Series specifically represents lightweight tie-rod hydraulic cylinders with a rated working pressure of 7 MPa, complementing the HOB Series (heavy-duty tie-rod cylinders) rated at 14 MPa.
The design of the Tie-Rod Hydraulic Piston Rod (MOB Series) combines structural simplicity with practical functionality. Its core features include:
The MOB Series utilizes four screws to connect the cylinder barrel and front and rear covers, which are then tightened with lock nuts. This design not only simplifies the structure but also makes installation and maintenance extremely convenient—simply loosen the lock nuts to remove the front cover and replace seals and other accessories.
Due to its relatively low operating pressure (7 MPa), the MOB Series cylinder components, such as the thinner barrel, smaller piston rod, cast front and rear covers, and relatively inexpensive, low-pressure seals, offer significant cost savings compared to cylinders of similar specifications.
The MOB lightweight tie-rod hydraulic cylinder offers a variety of mounting options, including flanges, single lugs, double lugs, foot mounts, and hinged shafts. The piston rod can also be fitted with accessories such as fisheye joints and I-type joints. This flexibility allows it to adapt to the installation requirements of various mechanical equipment.
The Tie-Rod Hydraulic Piston Rod (MOB Series) is suitable for operating environments with a pressure range of 0-7 MPa. It offers excellent low-speed performance and stable cushioning. Cylinder diameters typically range from φ32 to φ100 mm, but some models also offer inner tube diameters of 32-125 mm. A wide range of stroke options is available, from 10 mm to 2000 mm, with some even reaching 3000 mm, making it suitable for long-stroke applications.
Raw Material Selection: First, high-quality alloy steel is selected, ensuring its chemical composition meets industry standards to provide the necessary strength and toughness.
Heat Treatment: Through heat treatment processes such as quenching and tempering, the material’s internal structure is improved, enhancing its hardness and wear resistance to withstand high-load operating conditions.
Forming: Precision machining techniques are used to shape the alloy steel into the desired piston rod shape, ensuring accurate outer diameter and length.
Surface Treatment: Chrome plating or other coatings are used to create a smooth, wear-resistant surface for the piston rod, enhancing its corrosion resistance.
Quality Inspection: Each piston rod undergoes rigorous inspection before shipment, including dimensional inspection, mechanical property testing, and corrosion resistance testing, to ensure compliance with industry standards.
The Tie-Rod Hydraulic Piston Rod (MOB Series) is widely used in various industries due to its affordability and applicability:
It is widely used in the hydraulic systems of machinery and equipment such as machine tools, textiles, plastics, and agriculture. It is particularly suitable for applications with low system pressure and where cost-efficiency is a priority.
It can be used as a replacement for pneumatic cylinders. When a pneumatic system requires more stable movement or lacks sufficient pneumatic force, the MOB cylinder provides an ideal alternative.
The MOB Series is also widely used in various types of machinery, including construction machinery, mining machinery, metallurgical machinery, and construction machinery, as well as automated production assembly lines, robots, and opening and closing systems.
The MOB Series Tie-Rod Hydraulic Piston Rod supports a variety of customization and special configurations to meet specific needs:
High-temperature operating conditions: High-temperature seals are available.
Stroke control: A travel switch can be added or a magnetic sensing cylinder can be constructed (using a stainless steel cylinder, a copper piston, and a magnetic switch).
Motion control: A cushioning function can be added.
Special configurations: A dual-rod cylinder (MOD Series) is available.
Some suppliers also offer custom services. For large quantities, custom molds can be made, while for smaller quantities, turning can be used.
Selection, Installation, and Maintenance Recommendations
When selecting a Tie-Rod Hydraulic Piston Rod (MOB Series), consider factors such as operating pressure, required thrust/pull force, stroke length, installation space, and operating environment. During installation, ensure the mounting surface is clean, level, and rigid enough to support the cylinder and its load. Proper hydraulic connections and the use of recommended seals are crucial to preventing leaks.
Routine maintenance includes:
Regular Inspection: Visually inspect the piston rod surface for scratches, corrosion, or signs of leakage.
Lubrication: Use an appropriate lubricant according to the manufacturer’s recommendations.
Seal Replacement: If leaks are detected, inspect and replace worn or aged seals promptly.
The MOB Series design simplifies maintenance; internal parts can be replaced by simply loosening the lock nut.
With technological advancements and changing market demands, the development trends of the Tie-Rod Hydraulic Piston Rod (MOB Series) will be reflected in the following areas:
New Material Application: We will continue to research and develop new, high-performance alloy materials to enhance the wear and corrosion resistance of the piston rod to meet even more demanding operating environments.
Smart Manufacturing Technology: The introduction of smart manufacturing technology to improve production efficiency and pipe quality control will become a key direction for industry development.
Environmental Protection and Sustainable Development: During production, companies will prioritize environmental protection, adopting clean production processes and material recycling mechanisms to meet the requirements of sustainable development.
Demand for Customized Products: With the diversification of the market, customer demand for customized tie rod hydraulic piston rods is increasing, requiring manufacturers to flexibly adjust their production strategies to meet this demand.
Application of New Technologies: With the continuous advancement of hydraulic system technology, MOB series piston rods will find more applications in emerging fields such as smart devices and robotics.
