01 Design
Our engineers are with you every step. We deisgn the cylinders per your real requires. Our engineers also use advanced calculation tolls and design software to design the hydraulic cylinders that meet your needs and requirements.
02 Turning and Milling
Turning and Machining play a key part in manufacturing process.
Our advanced CNC turning and milling machines are specifically calibrated to handle the precise machining of cylinder tubes, rods, and other key components.
Turning Process:
We perform precision turning to achieve exact dimensions, smooth surface finishes, and optimal concentricity for seamless welding and assembly. Our CNC lathes feature driven tooling capabilities, allowing us to execute complex operations, including threading, grooving, and contouring, ensuring the highest level of accuracy for hydraulic cylinder components.
Milling Process:
Complementing our turning operations, high-precision milling ensures perfectly machined mounting interfaces, ports, and other critical features. This step enhances structural integrity and functionality, meeting the rigorous demands of industries such as mining, construction, and agricultural machinery.
03 Heat treatment
Heat treatment is a crucial step in our hydraulic cylinder manufacturing process. By precisely controlling temperature and quenching techniques, we enhance the hardness, strength, wear resistance, and corrosion resistance of cylinder tubes, piston rods, and other critical components. Additionally, stress-relieving heat treatment ensures dimensional stability and durability, preventing deformation and premature wear.
04 Welding
At Stable Cylinders, we offer advanced manual welding, circular welding, and robotic welding for components up to 18 meters in size. We weld end caps, lugs, collars, connections, flanges, brackets, and various types of customised components.
Additionally, we utilise inductive heat treatment to minimise deformation. The combination of advanced technology and skilled welders enables us to deliver robust and reliable hydraulic cylinders for all types of applications.
05 Cleaning
Cleaning is vital for maintaining the cleanliness and quality of our components, pipes, and rods. We utilise custom-designed washing equipment capable of handling long and large hydraulic cylinders. Cleanliness significantly impacts hydraulic system performance and lifespan, prompting us to consider the cleaning process early in the design phase. Our equipment effectively eliminates contaminants and particles that might affect system operation. By prioritising cleaning as a core process in our production, we ensure that all parts meet strict cleanliness standards, ensuring quality and reliability.
06 Assembly
Our experienced assembly team guarantees flawless hydraulic cylinder production—no matter the size, complexity, or specialized design. With decades of hands-on expertise, we handle custom, heavy-duty, multi-stage, and non-standard cylinders, ensuring every component aligns with precision.
The teams are tailored for various sizes of hydraulic cylinders, and we use specially designed tools for precise and rapid assembly according to specifications. Heating and cooling are used to expand and shrink components during assembly. All in all we can adapt to different customer needs, regardless of the type or size of cylinder.
07 Testing
We test every hydraulic cylinder to ensure perfect function, strength, and cleanliness before delivery.
Key Tests We Perform:
✔ Functional Testing – Checks smooth operation under working conditions.
✔ Leak Testing – Uses oil or air pressure to confirm zero leaks.
✔ Cleanliness Inspection – Optical checks remove harmful contaminants.
✔ Durability Tests – Simulates real-world loads to verify long-term performance.
✔ Cycle Testing – Repeated stress tests for fatigue resistance.
Our strict ISO-certified testing process guarantees high-performing, leak-free, and long-lasting hydraulic cylinders—perfect for mining, construction, and industrial machinery.
