​Welded hydraulic cylinders

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

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.
