Qualiseal Contacting Face Seal

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.

Features & Benefits

  • Achieve low leakage rates while managing axial shaft movement
  • Easy, fast installation minimizes downtime and maintenance costs
  • Designed to tolerate pressure reversals
  • Can utilize either an O-ring on the outer diameter in a slip fit application or can be designed to press-fit into the seal bore of your unit
  • Unbalanced or balanced designs
  • Several elastomeric compounds, metal bellows or spring energized secondary sealing options are available for a variety of fluid and temperature applications
  • Take-apart or unitized seal design
  • Seal designs incorporate seal face material grades to encompass a wide range of applications, including high-pressure velocity (PV) or extreme vibration applications
