A foil bearing allows bi-directional rotation of a shaft. The foil bearing includes a plurality of thin compliant foils secured to a housing, and spring segments underlying the foils. Each spring segment has a first stiffness profile in a first zone and a second stiffness profile in a second zone. The first stiffness profile allows rotation in one direction, and the second stiffness profile allows rotation in an opposite direction.
