ABSTRACT:
A gas supported bearing includes a first stationary bearing element having a longitudinal axis and a first bearing surface. A second rotating bearing element is coaxially aligned with respect to the first bearing element and includes a second bearing surface. A pneumatic load ramp is formed in one of the bearing surfaces to apply an asymmetric load to either bearing element to eliminate bearing whirl instability.
