Subject field(s)
  • Bearings and Bearing Systems (Mechanical Components)
DEF

A type of hydrodynamic bearing.

CONT

The shaft [of a foil bearing] is supported by a compliant, spring loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air), lifts the foil from the shaft so that there is no contact. The shaft and foil are separated by the viscous properties of the working fluid. A high speed of the shaft with respect to the foil is required to initiate the air gap.
