ABSTRACT:
A hydrodynamic process or gas bearing is disclosed which includes an integral thrust disk defining a plurality of foil elements, the radially outer edge of the disk being displaced from the major bearing surface to form a circumferential step having a varying height profile. The integral thrust disk may in the alternative or in addition, include a plurality of radially outwardly extending tabs to locally increase the flexural rigidity of the disk.
