Air Bearing Spindle Containing Glass Journal Bearing Sleeve Coated with Tin Dioxide (SnO2)

      Disclosed is a glass journal bearing sleeve coated with tin
dioxide for use in air bearing spindles.

      Air bearing spindles require a cylindrical journal bearing
sleeves with very precise dimensions.  Such sleeves may be
economically produced from glass, where a precision metal mandrel is
used to grind the glass sleeves to the precise required dimensions.

      The glass sleeves are then coated with tin dioxide to prevent
the sleeves from developing cracks during assembly, and from wear
during normal operation.  The tin dioxide may be chemically doped to
give it semiconductive characteristics.
