Duo Cone Seals

Duo cone seals are a reliable sealing solution for the final drives and track rollers of earth-moving machines such as wheel loaders, articulated road trucks, bulldozers, motor graders, excavators, crop harvesters and screw conveyors. Their simple yet robust structure delivers effective sealing performance by preventing lubricant leakage，while blocking external contaminants from entering the machine’s transmission system.

At Decent Machinery, we are well equipped to supply all types of duo cone face seals compatible with the majority of aftermarket part numbers. These seals are manufactured to rigorous standards to meet the requirements of major construction machinery brands, including Caterpillar, Hitachi, Komatsu, Volvo and more.

Decent Machinery supplies duo cone seals of the highest quality. Here, we provide mechanical face seals for all types of equipment and applications. Our duo cone seals are rigorously tested and inspected with the strictest specifications in mind to guarantee that our customers are getting one of the best heavy-duty seals on the market.

Specifically designed for heavy duty, rotating applications, Decent Machinery floating seals are made from two kinds of material, one is high chromium molybdenum (FC15Cr3Mo) and the other is Nihard (high-nickel alloy) to withstand extreme wear and tear. So, if you are looking for a face seal that is going to work just as hard as you do and that will keep your equipment running longer and more efficiently, Decent Machinery is the sealing specialists for you!

All About Duo Cone Seals

Duo cones, also referred to as Face seals, are used to seal against the harsh environments that their heavy equipment was exposed to. They are a combination seal that is made out of both metal seals and a toric loader that is a soft rubber or elastomer-based ring. The Duo Cone or face seal function is primarily used to protect against leakage and contaminants from entering or leaving rotating elements (such as shafts, wet brakes, drive motors, etc.) from a mixture of internal and external environmental factors. This means that these mechanical face seals will protect the vital components of your equipment from foreign materials as they rotate.

What Else Can Face Seals Be Called?

There are several other names that the seals go by! Some of these names include Duo Cone seals, mechanical face seals, heavy-duty seals, toric seals, metal face seals, face seals, dynamic face seals or floating seals.

What Types Do Floating Seals Come In?

• O-Ring Type Face Seals: As the more common type of floating seal, a toric elastomer O-ring is used in this seal.
• Trapezoid Type Face Seals: Instead of an O-ring, the Trapezoid elastomer toric ring is used.

Both styles of seals are two metal seals that sit against each other (which is why they are also referred to as “floating” seals) with a wedged gap that allows for easy lubrication. Only one half of the duo cone seal rotates, while the other half remains static. By combining these two halves, you have a leak proof seal designed to withstand the most severe and challenging environments!

Application Advantages of Dual Cone Seals

The dual cone seal stands out among many sealing products due to its significant application advantages:

FAQs on Duo Cone Seals

Q1. What is a duo cone seal?

A: Duo-Cone seals are a special kind of sealing solution for rotating mechanical components.

Q2. What must a duo cone seal be resistant to?

A: Duo cone seals or face seals are specifically engineered for rotating applications in harsh environments where they withstand severe wear and prevent entry of harsh and abrasive external media. Moreover, they are corrosion resistant and can withstand extreme low and high operation temperatures.

Q3. What is the material of the duo cone seal?

A: These seals are composed of two metal faces and two flexible toric rings that force those faces together so that they form a tight seal. They are typically made from NBR, VMQ, HNBR, and FKM.

Q4. What is the function of a duo cone seal?

A: The duo cone seal functions to protect the shaft and inner parts against wear and tear. Moreover, the seal helps to prevent any leakage from the inner to the external part.
