Brush Seals

       Compliant brush sealing systems from Waukesha Bearings can be applied to a wide variety of rotating equipment in air, steam, or process gas applications to reduce the leakage gap between the sealing surface and rotor.

      The compliancy of a brush seal allows the bristles to deflect with minimal wear, thereby maintaining a small leakage gap over time and increasing operational efficiencies.
