A high-speed rotor, supported by gas-lubricated foil bearings, is free from self-excited whirl and displays no loss of load capacity when vibrated at frequency equal half the rotational speed [1 ].* It is demonstrated here that in addition to tolerance of geometrical imperfections, misalignment and foreign'particles'[ 3, 4], the foil bearing performs well at elevated temperatures and accommodates appreciable temperature gradients. The foil bearing is endowed with superior wipe-wear characteristics and the flexibility of the foil accounts not only for the stability of the foil bearing, but also for its forgiveness with respect to distortion, contamination and contact.
