Contacting Face Seals

Pushing the outer limits of speed and vibration with your critical application?

We have two words for you. No problem.

Qualiseal’s contacting face seals are known for versatility and exceptional performance across a wide range of demanding aircraft and industrial applications. They are designed for optimum performance where high speed and vibration are the norm.

As the stationary portion of a seal assembly, contacting face seals are generally paired with a rotating mating ring, bearing or shaft. The seal face in the stationary portion provides the low-friction wear element that rides on the harder wear-resistant mating surface. The seal face and mating surfaces are typically lapped flat to within 0.0000348 inches (3 helium light bands), which provides virtually leak-tight sealing between the sealing interface.   

With the aid of Finite Element Analysis (FEA), mechanical face seal design at Qualiseal Technology is optimized to meet or exceed the most extreme unit operating conditions, with long life and reliable performance.
