Ball Bearing Ceramic Ball

Ceramic (silicon nitride) balls feature highly controlled and consistent geometry as well as an exceptionally smooth and uniform surface finish. Compared to steel, the material's lighter weight, higher stiffness, and inert properties facilitate higher operating speeds, extended bearing life, and expanded design possibilities for unique and demanding bearing applications.
Typical Applications
  • Semiconductor processing (high vacuum)

  • Medical and dental handpieces

  • Turbo molecular pumps

  • Flow meters

  • Scanners

  • Micro turbines (power generation)

  • Aircraft instrumentation

  • Machine tool spindles
