Abstract
A journal foil air bearing supports a load along the radial direction of a rotating shaft. The bearing includes a top foil, a bump foil, and a base foil. The top foil faces the shaft, while the bump foil acts as an elastic member surrounding the top foil. The base foil, a circular pipe member, houses the bump foil. A separation preventer, protruding from the base foil without touching the shaft, restrains the bump foil from moving along the shaft's longitudinal direction. This design prevents the bump foil from escaping during operation, which maintains bearing performance and mitigates secondary damage from contact with other components.
