Welded High Pressure Hydraulic Cylinders

Cylinder Barrel: The main body of the cylinder that holds the piston and is subjected to high pressure.

Piston: This key component separates the two sides of the cylinder and moves back and forth as hydraulic fluid is pumped in and out.

Piston Rod: The piston rod is attached to the piston and extends outside the cylinder to transfer the force generated to the intended application.

Piston Rod Fitting: Secures the piston rod as it slides in and out and contains seals to prevent fluid leakage.

Base: The other end of the cylinder, usually welded to the barrel, which may have hydraulic fluid ports.

Seals: Strategically placed to prevent fluid leakage and maintain pressure inside the cylinder.

Ports: They are the channels through which hydraulic fluid enters or exits the cylinder, allowing the piston to move.


Topa as one of the best high pressure hydraulic cylinders manufacturers, we are committed to producing the finest hydraulic cylinders available. Our cylinders are usually cylindrical with a visible piston rod extending from one end and a sturdy base at the other. The exterior is usually coated with a corrosion resistant material that shows the toughness and quality of the cylinder. These cylinders are made of high-strength steel or alloys that can withstand harsh conditions.

In terms of operation, fluid is pumped into both sides of the piston in the cylinder, allowing for controlled movement in both the extension and retraction directions. This double-acting feature makes them suitable for a variety of applications. These cylinders are typically available in pressure ranges from 3,000 to 5,000 psi for a variety of heavy-duty tasks. Stroke length or piston travel can be tailored to specific needs.


Durability: Made from high-strength materials, these cylinders are built to last, even under challenging conditions.

Precision Control: The double acting design allows for precise control in both extending and retracting movements.

High Pressure Capability: With a pressure range typically between 3,000 to 5,000 psi, they are ideal for heavy-duty applications.

Versatility: The adjustable stroke lengths make these cylinders suitable for a variety of tasks.

Efficiency: These cylinders convert hydraulic power into mechanical force efficiently, optimizing performance.


Construction Equipment: In bulldozers, excavators, and cranes for lifting and moving heavy loads.

Manufacturing: Used in machinery for pressing, bending, and assembling parts.

Automotive Industry: Essential for vehicle lifts and assembly processes.

Agriculture: In tractors and harvesting equipment for various farming operations.

Mining: Used in heavy-duty drilling and earth-moving machinery.

Marine Applications: In ships and docks for loading and unloading heavy cargo.

Welded High Pressure Hydraulic Cylinders

The manufacturing process for Topa high pressure double acting welded hydraulic cylinders begins with the selection of quality materials to ensure strength and durability. Components such as cylinder barrels, pistons and piston rods are expertly machined for precise dimensions and smooth operation. During the welding process, great attention to detail is paid to ensure strong, leak-proof joints. These components are assembled using systematic assembly for optimum performance and efficiency.

Next each cylinder undergoes a series of rigorous tests to ensure it meets your standards for use. This includes a pressure test to verify the cylinder’s ability to withstand and operate under high pressure conditions. Leak tests are also performed to ensure the integrity of seals and fittings.
