Qualiseal® Contacting Face Seals

Pushing the outer limits of speed and vibration with your critical application? We have two words for you. No problem. Qualiseal® Technology 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.
