What Is a Hydraulic Cylinder?

A hydraulic cylinder is a mechanical actuator that converts hydraulic energy into linear force and motion. It consists of a barrel, piston, and rod, which work together to generate the power needed for lifting, pushing, pulling, or holding heavy loads.

Hydraulic cylinders are used across various industries, including construction, agriculture, manufacturing, material handling, and oil & gas. Choosing the right one depends on multiple factors, including load capacity, space constraints, operating conditions, and precision requirements.

Types of Hydraulic Cylinders & Their Applications

Welded Body Cylinders

These cylinders have a compact and robust design, with the barrel welded directly to the end caps. This makes them ideal for high-pressure and heavy-duty applications where space is limited.

Best for: Construction equipment, material handling, mobile hydraulic systems.

Telescopic Cylinders

Telescopic cylinders extend in multiple stages, allowing for an exceptionally long stroke from a compact retracted length. These are commonly used where space is tight but long extension is required.

Best for: Dump trucks, cranes, heavy lifting machinery.

Single-Acting vs. Double-Acting Cylinders

• Single-acting cylinders apply force in one direction using hydraulic pressure, with a spring or gravity returning the piston to its original position.
• Double-acting cylinders use hydraulic pressure to move in both directions, offering greater control and precision.

Best for: Applications requiring precise movement and efficiency, such as automated machinery.

Hollow Rod Cylinders

Hollow rod cylinders feature a hollow piston rod, which allows for applications requiring fluid or mechanical passage through the cylinder. They are commonly used in specialized machinery where routing components through the rod is beneficial.

✔ Best for: Precision applications, specialized hydraulic systems.

Piggy Back Cylinders

Piggyback cylinders consist of two cylinders mounted in parallel, effectively doubling the stroke length without increasing overall space requirements. They are used when extra-long stroke lengths are needed but space constraints prevent using a single, extended cylinder.

✔ Best for: Material handling, lifting applications, heavy machinery.

Cushioning Cylinders

Cushioning cylinders are designed with built-in dampening systems that slow down the piston at the end of the stroke, reducing shock and impact. This helps prevent mechanical stress on machinery and extends the life of components.

✔ Best for: Applications requiring smooth, controlled stopping, such as industrial presses and conveyor systems.

Big/Large Bore Cylinders

Large bore cylinders have greater piston diameters, allowing them to produce higher force outputs at lower pressures. They are designed for heavy-duty industrial applications where significant power is required.

✔ Best for: Construction, mining, oil and gas, and large-scale manufacturing.

Key Factors to Consider When Selecting a Hydraulic Cylinder

1. Load Capacity & Force Requirements

How much weight does your cylinder need to move? The required force depends on both the bore size and the hydraulic pressure available. A larger bore diameter or higher pressure increases the force output.

Formula: Force = Pressure × Piston Area (F = PA)

2. Stroke Length & Space Constraints

The stroke length is the distance the piston travels from fully retracted to fully extended. Consider the space available for installation and ensure the cylinder fits without restricting movement.

3. Mounting Options & Stability

Mounting style affects cylinder performance and longevity. Common options include:

• Flange mounts (for high-force applications)
• Clevis mounts (for pivoting motion)
• Trunnion mounts (for angular movement)

4. Environmental Considerations

If your equipment operates in extreme conditions, select a cylinder with corrosion-resistant coatings, specialized seals, and durable materials.

For harsh environments: Use nitrocarburized surfaces or stainless steel.

5. Speed & Precision Requirements

Some applications require fast extension and retraction, while others demand slow, controlled movement. Ensure your cylinder type matches the speed and accuracy needed for your operation.

6. Material Selection: Steel vs. Aluminum

• Steel cylinders are stronger and better suited for high-pressure applications.
• Aluminum cylinders are lightweight and easier to transport, but they have lower strength limits.

Industry-Specific Hydraulic Cylinder Applications

Construction & Heavy Equipment

Excavators, loaders, and bulldozers rely on welded hydraulic cylinders for high-pressure and rugged performance. Durability is crucial for these high-load applications.

Selecting an appropriate hydraulic cylinders is of utmost importance to ensure smooth interactions and processes, especially in industries such as construction, crane manufacture, and road machinery. Hydraulic cylinders facilitate the lifting of great masses, control movement direction, and elaborate the action itself to avoid jerks. In this guide we will explain all of the most essential features and parameters of hydraulic cylinders and their applications, as well as how to select the most suitable alternative.

What Are Hydraulic Cylinders?

As mechanical actuators, hydraulic cylinders translate the pressurized hydraulic fluid into linear force and movement. Hence, they are responsible for performing the inverse operation; they take fluid energy and convert it to mechanical motion or force. This type of actuator is essential in any application requiring force to be applied steadily in a single direction of movement. Construction, manufacturing and heavy engineering are industries where these are widely used. The popularity of these devices is due to their durability, reliability and strength.

Types of Hydraulic Cylinders

1. Single-Acting Cylinders
   These cylinders provide force in one direction only, ideal for simpler applications where retraction relies on an external force like gravity.
2. Double-Acting Cylinders
   Commonly used in industries that require both push and pull forces, double-acting cylinders allow fluid pressure on both sides, ensuring better control in both directions.
3. Telescopic Cylinders
   Ideal for applications requiring extended reach, such as crane arms. Compact when retracted, these cylinders can extend to several times their length, perfect for height-related tasks.
