Cat® Duo-Cone™ Seals Deliver Long Life and Durability

Cheap seals are a bad deal. That’s because as much as 40% of your Cat® equipment’s drivetrain consists of wear items like gears, bearings and friction material. But with high-quality Cat Duo-Cone™ seals, your drivetrain can handle the stress of heavy-duty applications like mining.

Cat® drivetrain components are part of an always-improving system design, built by Caterpillar specifically for Cat mining equipment. They’re made to handle the stresses, operating speeds and temperature ranges of Cat machines working in demanding mining applications. But even drivetrains this powerful can be taken out of commission by a single failed seal.

Seals play a critical role in your drivetrain. They keep grease and oil in, and dirt, grit and water out. That’s why one low-quality seal can cripple a machine in minutes.

But Cat Duo-Cone™ seals are different. They’re made specifically with Cat equipment in mind. Plus, they’re designed to work and wear as a system. That means you get better performance and predictability and more hours between rebuilds — lowering the cost of production and ownership across the board.

Cat Duo-Cone seals are designed to handle the speed and pressure of heavy equipment. They’re built to last longer than competitor seals when put into critical components such as:

  • Axles

  • Pumps

  • Rollers

  • Idlers

  • Final drives

  • Undercarriages

To tailor to your specific needs, Caterpillar also provides manufacturing options such as:

  • Different rubber materials to tolerate various temperatures and oils

  • A range of metal ring materials that tailor a seal to its environment. This includes materials exclusive to Caterpillar, such as Ni-Hard and C6, the alloy of choice in large diameter wheel applications.

  • Sized radial cross sections to balance space claim and absorb system motion, ranging from 25mm to 940mm (The bigger the cross section, the longer the life.)

 

BUILT TO LAST

Caterpillar designed and built your machine’s drivetrain — no one knows it better. It’s designed to exacting standards, using only the highest quality proprietary components. Since patenting the Duo-Cone seal in 1965, the focus has been on perfecting the quality of the product and producing the best seals. That’s why Cat Duo-Cone seals are the only choice for keeping your machine in top condition.  

Your Cat dealer can equip your drivetrain with the best possible seals for a long, dependable life. Ask your Cat dealer about drivetrain solutions with Cat Duo-Cone seals.
