Flange Type Hydraulic Cylinder

Middle Flange Type Hydraulic Cylinder

Cylinder Barrel: The main body that houses the piston and the hydraulic fluid.

Middle Flange: A sturdy mounting point located at the cylinder’s midsection for secure attachment.

Piston: A disc or short cylinder fitting closely within the barrel, separating the two sides of the hydraulic fluid.

Piston Rod: Extends from the piston through one end of the barrel, translating the hydraulic force into linear motion.

Rod Gland: Contains the seals and wipers at the rod’s exit point, preventing leaks and contamination.

End Caps: Seal both ends of the barrel, containing the hydraulic fluid and withstanding internal pressure.

Seals: Ensure fluid does not escape from the cylinder and maintain pressure.

Ports: Allow the hydraulic fluid to enter and exit, controlling the piston’s movement.


A center flange hydraulic cylinder is a type of cylinder that is characterized by a flange in the middle of the cylinder body for mounting. These cylinders typically have a sleek cylindrical appearance with the center flange providing a distinct visual break in the length of the cylinder. This flange is usually strong and pre-drilled for safe installation.

The primary function of a center flange hydraulic cylinder is to convert hydraulic energy into linear motion. This is critical in applications that require precise control of the movement of heavy loads or mechanical parts. These cylinders are usually available in industrial colors, commonly black or metallic grey, but can also be customized.

The pressure range of center flange hydraulic cylinders varies widely, but they are typically designed to operate effectively at pressures from 1,500 to 3,000 PSI. Strokes also vary and are designed to meet the specific needs of the application, whether it be a short, powerful thrust or a long, steady stretch.


Secure Mounting: The middle flange allows for a balanced and secure mount, reducing stress on the cylinder during operation.

Space Efficiency: This design is ideal for applications with limited space, as it doesn’t require end mounting.

Versatility: They can be used in various orientations, providing flexibility in system design.

Durability: Typically constructed with robust materials, these cylinders withstand tough working conditions.

Precision: They offer precise control of movement, essential for many industrial processes.


Manufacturing Machinery: For precise control in automated manufacturing lines.

Mobile Equipment: In construction and agricultural machinery where space optimization is crucial.

Material Handling: Used in conveyor systems and lifting equipment.

Engineering Vehicles: Such as in steering mechanisms of large vehicles.

Aerospace and Defense: Where precision and reliability are paramount.

Middle Flange Type Hydraulic Cylinder

The quality assurance process for Topa center flange hydraulic cylinders begins with a rigorous visual inspection. This step ensures that the appearance of the cylinder meets our cylinder standards. Next, we perform precision testing to measure the exact dimensions and alignment of each cylinder, confirming that each component fits perfectly and operates as intended.

Next, our cylinders are dynamically tested under a variety of pressure conditions to simulate actual use. This includes leak testing to ensure the integrity of the seals and the overall structural integrity of the cylinder. Cylinders are only approved for delivery if they have passed all these rigorous tests and performance and safety have not been compromised in any way.
