Double Acting Cylinders

A double acting cylinder is an essential piece of equipment for any business that relies on hydraulic power. But what are double acting cylinders, and how do they work?

This guide will explain everything you need to know about double acting cylinders, including their advantages and disadvantages. We’ll also provide a comparison between single and double acting cylinders, so you can decide which type is right for your business.

So, if you’re ready to learn more about double acting cylinders, let’s get started!

1. What Are Double Acting Cylinders?

The double acting cylinder is a type of pneumatic or hydraulic cylinder in which compressed fluid is used to push the piston in both directions. This allows for linear actuation in both directions, as opposed to the single acting cylinder, which can only push the piston in one direction.

Double acting cylinders typically have a larger bore than single acting cylinders and can produce more force. They are also more versatile, as they can be used for applications that require linear actuation in both directions.

2. A Quick History

Double acting cylinders have been used for centuries to create a powerful force that can move an object in one or more directions. Though technology has evolved over the years, the general concept remains the same. Here’s a quick look at the history of double acting cylinders.

17th Century

The first double acting cylinders were created in the 17th century by English inventor Thomas Savery. These early cylinders were used to pump water out of mines. The double acting cylinder allowed for a much more powerful force than a single-acting cylinder, making it possible to pump water from greater depths.

18th Century

In the 18th century, double acting cylinders began to be used in steam engines. Scottish engineer James Watt was the first to use double acting cylinder pump in a steam engine. His design was more efficient than earlier designs and quickly became the standard.

19th Century

As double acting cylinders became more common, they were used for a variety of applications. In the 19th century, they were used in locomotives and steamboats. They were also used in pumps, compressors, and other machinery.

Today

Today, double rod hydraulic cylinders are still used in a variety of applications. This includes everything from construction equipment to automotive engines. They are an essential part of many machines and will continue to be used for years to come.

3. How Does It Work?

A double-acting cylinder work by having a port on each end that is connected to a pressure source. As the pressure in one side of the cylinder increases, it causes the piston to move in that direction.

This, in turn, decreases the pressure on the other side of the piston, causing it to move in the opposite direction. The double-acting cylinder can be used to create linear or rotary motion, depending on how it is configured.

4. Main Components

A double acting cylinder has several key components that work together to produce linear motion. These components include:

Piston

The piston is the central component of the cylinder and contains a seal that separates the two chambers within the cylinder. The piston is connected to the rod, which extends from the cylinder to create linear motion.

Piston Rod

The piston rod is attached to the piston and extends from the cylinder. The rod is typically made of steel or another strong material that can withstand high temperatures and pressures.

Tie Rod

Tie rods are used to connect the two ends of the cylinder together. They help to support the weight of the piston and rod and prevent the cylinder from moving during operation.

Barrel

The barrel is the pressure-tight cylindrical body of a double acting cylinder. It houses the piston and sealing elements, and provides a means of attachment for the rod(s) or other linear actuator components.

Cap End

The cap end is the closed end of the double acting cylinder. It houses the rod seal and gland and provides a place for mounting the cushions. The cap end also contains the ports that provide air to enter and exit the cylinder.

Rod End

The rod end of a double acting cylinder is the part that connects to the load. It typically has a male thread or a clevis mount. The rod end contains a seal to prevent fluid from leaking out of the cylinder.

These are the main components of a double acting cylinder. Each serves a specific purpose and works together to create linear motion.

5. Key Features and Benefits

There are many features and benefits that dual action hydraulic cylinders offer. Here are some of the key ones:

Higher Force Output

Double acting cylinders can produce double the force of a single acting cylinder of the same size. This is because they use both sides of the piston to generate force, rather than just one.

Faster Actuation

With double acting cylinders, both the extension and retraction phases of the stroke are much faster because the air can flow in either direction. This is due to the double acting cylinders having two ports that allow for air to enter and exit on both sides of the piston.

Reversibility

Because double acting cylinders can act in both directions, they are able to easily change the direction of their force. This makes them very versatile and suitable for a wide range of applications.

Higher Efficiency

Double acting cylinders are more efficient than single acting cylinders because they don’t rely on gravity to return the piston to its original position. Instead, they use the air pressure that is exerted on both sides of the piston.

Smooth Operation

Small double acting hydraulic cylinder provides a smoother operation. This is because the force is applied evenly throughout the stroke, both in the extension and retraction phases.

These are just some of the key features and benefits that double acting cylinders offer. With so many advantages, it’s no wonder they are so popular choice for a wide range of applications.

7. The Difference Between a Single and Double Acting Cylinder

There are two different types of cylinders: single acting and double acting. There are a few key differences between the 2 types that set them apart. Here are the key differences between them:

Single Acting Cylinder	Double Acting Cylinder
used for light-duty applications	used for more heavy-duty applications
have a piston that is only actuated on one side	have a piston that is actuated on both sides
produce force in one direction	produce force in both directions
can only be retracted by an external force, such as gravity	can be retracted by the internal force of the piston
typically less expensive than double acting cylinders	more expensive because they require more parts and are more complex

#1 Application

Single acting cylinders are typically used for light-duty applications whereas double acting cylinders are used for more heavy-duty applications. This is because double acting cylinders can produce more force than single acting cylinders.

#2 Design
