Silicon Carbide Bearing Applications:

Silicon carbide (SiC) bearings excel in demanding environments where traditional bearings fail. Key applications include:

  • High-Temperature: Industrial furnaces, kilns, heat treatment.
  • Corrosive Environments: Chemical processing, oil & gas, marine.
  • High-Speed: Machining, turbomachinery, aerospace.
  • Semiconductor Manufacturing: Wafer processing equipment.
