Trunnion Mounted Cylinder

If you use trunnion-mounted cylinders in your business, then you know how important they are for a variety of tasks. From moving heavy loads to providing precise control in manufacturing applications, these cylinders play a vital role. But what do you really know about them? 

In this ultimate guide, we’ll explore everything there is to know about trunnion-mounted cylinders, from how they work to the different types available on the market. We’ll also provide some tips on choosing the right cylinder for your needs and the steps to take when importing them from a manufacturer.

So, if you’re ready to learn more about trunnion-mounted cylinders, then let’s get started!

1. What Is Trunnion Mounted Cylinder?

Trunnion-mounted cylinders are heavy-duty pivoting cylinders with pintles attached to the head, cap, or intermediate position. This allows for more stability and higher pressure than a traditional rod-end cylinder. The result is a smoother, more powerful operation that can be used for a variety of applications.

The trunnion mounted telescopic cylinder is supported on both ends, rather than just one. This added support helps to keep the barrel from wobbling or bending under high pressure, which can cause problems with seals and other components. These cylinders are often used in applications where precision and power are essential.

2. How Does It Work?

A trunnion-mounted cylinder is a type of hydraulic cylinder that uses two pivot points to create linear motion. The piston is mounted on a trunnion, which rests in a bearing and allows the piston to rotate. This rotation creates the linear motion needed to power hydraulic machinery.

The basic operation of a trunnion-mounted cylinder is similar to that of any other hydraulic cylinder. The piston rod is attached to the piston, which moves in and out of the barrel as pressurized fluid is admitted or released from the chamber.

The difference lies in how the barrel is mounted: on a fixed mount, it would be bolted or welded in place; on a trunnion mount, it can pivot around the mounting pin, allowing for greater flexibility in alignment with the load vector.

3. Main Components

A trunnion-mounted cylinder has 6 main parts. Let’s go over them one by one.

Cylinder Body

The cylinder body is the longest part of the trunnion-mounted cylinder. It’s where the piston and other components are housed. The cylinder body typically has a diameter of 2 to 12 inches.

Rod

The rod is the part of the trunnion-mounted cylinder that connects the piston to the trunnion. It is usually made of high-strength steel to withstand the high pressures of hydraulic fluid.

Piston

This part of the cylinder is what actually moves the load. The piston is connected to the rod, and it has a seal that prevents fluid from leaking out of the cylinder.

Trunnion

The trunnion is the part of the trunnion-mounted cylinder that allows it to rotate. It’s a round, cylindrical piece that’s attached to the base of the cylinder.

Base

The base is the part of a trunnion-mounted cylinder that sits on an open surface. It’s typically 6 inches in diameter and made with durable material to support heavy tools or machinery.

End Caps

The end caps are the parts of the trunnion hydraulic cylinder that seal the ends of the cylinder body. They prevent fluid from leaking out and keep debris from getting inside the cylinder.

4. Key Features and Benefits

When it comes to choosing the right hydraulic cylinder for your particular application, it is important to consider all of the features and benefits that each type of cylinder has to offer. Here are the most important features and benefits of trunnion mounted cylinder that you should keep in mind:

High-Degree in Side Load Protection	Thanks to the fact that the trunnion is mounted on the side of the cylinder, rather than on the top or bottom. This gives the cylinder added stability and helps to protect it from damage caused by side loads.
Improved Rod Sealing	The side-mounting of the trunnion also helps to improve the sealing around the rod, which in turn helps to prevent leaks and extends the life of the cylinder.
Compact Design	Trunnion mounted hydraulic cylinders are typically smaller and more compact than other types of cylinders, making them ideal for applications where space is limited.
Simplified Mounting Options	Trunnion cylinders are the perfect choice for those looking to mount their cylinder quickly and easily. They only require two mounting points, which makes it easy when compared with other types of systems that often require four or more screws into different surfaces to get them mounted properly.
