Welded hydraulic cylinders
Product Description
Product Detail
I.Welded hydraulic cylinders act as main working parts in hydraulic systems, built for heavy-duty tasks.
They come with a fully welded body that does not use external tie-rods.Different from traditional tie-rod hydraulic cylinders, they connect the cylinder tube, rear end cover, oil port and mounting base through precision welding. This structure makes the cylinder more compact, and eliminates risks such as loosening and breakage of tie-rods. It has become the preferred choice for hydraulic systems of heavy machinery.
II. Core Parameters: Rigid Indicators for Extreme Working Conditions
Core Performance Parameters
- Pressure Level: Standard 16MPa-35MPa, custom up to 40MPa
- Structure Size: Bore 50mm-500mm,stroke 100mm-6000mm (customizable)
Key Components & Configuration
- Key Components: 45# precision seamless steel tube (honed inner wall); 40Cr hard chrome-plated piston rod
- Sealing System: Imported NBR/FKM seals (working temperature: -40℃ to 120℃)
- Mounting Types: Clevis, flange, foot, trunnion & custom options
III. Core Advantages: Three Highlights to Solve Industrial Pain Points
3.1 High Rigidity and Outstanding Load Resistance
The fully welded structure improves overall rigidity by more than 30%. It handles side loads and impact loads well, so it won’t warp or come loose in tough conditions.
3.2 Strong Adaptability and High Space Utilization
The compact, tie-rod-free design fits neatly into tight installation spaces. In the same space, welded hydraulic cylinders can have a bigger bore and longer stroke to deliver more pushing force.
3.3 Reliable Sealing and Clear Maintenance
Welded oil ports reduce leakage points. The front cover can be disassembled for seal replacement with standard tools. Daily maintenance is simple, which greatly reduces equipment downtime.
IV. Application Scenarios: Focus on Heavy-Duty Fields
Welded hydraulic cylinders fit right into all high-pressure, heavy-load and tough work settings:
Construction Machinery: Loader lift and tilt rams, crane outrigger cylinders, concrete pump truck arms.
Mining and Metallurgy: Mine dump truck lift cylinders, metallurgical push cylinders.
Special Vehicles: Tipper truck rams, garbage compactor cylinders, aerial lift telescopic cylinders.
New Energy and Marine: Wind turbine yaw cylinders, offshore platform lift cylinders.
Agricultural Machinery: Large harvester cylinders and other continuous working parts.
V. Selection and Customization: Precise Matching for Various Equipment
We can fully customize welded hydraulic cylinders according to your equipment and working conditions:
Thicker tube walls for high-pressure jobs
Stainless or ceramic-coated rods for corrosive areas
Single or multi-stage telescopic designs for long-stroke uses
Our full OEM & ODM service covers design and production, so every cylinder fits your machine properly.
