The present invention provides a foil journal bearing including at least one support pad mounted inside a journal sleeve, and onto which foils are mounted. The support pad is mounted to the journal sleeve in a manner allowing it to tilt in response to foil loading variations and shaft misalignment.

The present invention provides a foil journal bearing including at least one support pad mounted inside a journal sleeve, and onto which foils are mounted. The support pad is mounted to the journal sleeve in a manner allowing it to tilt in response to foil loading variations and shaft misalignment. The present invention further provides a foil thrust bearing including at least one support pad mounted to a thrust plate and onto which the foils are mounted. The support pad is similarly mounted in a manner allowing it to tilt. The support pads in either configuration may be tapered in thickness to provide an optimized compliant backing for the foils.
