Magnetic fluid seals

  • Magnetic fluid seals
  • Magnetic fluid seals are seals using magnetic fluids, which have the characteristic of being drawn to magnets.

    Unlike conventional oil seals and mechanical seals, magnetic fluid seals are seals that maintain clean sealing performance achieved by fixing a magnetic fluid around the rotating shaft with a magnet to make fluid O rings.
    They are used as dust seals for hard disk drive manufacturing equipment and as vacuum seals for semiconductor manufacturing equipment and liquid-crystal display manufacturing equipment, which must be operated in a clean environment.
