A fluid bearing in which parts of the bearing land are free to move relative to the bearing member on which they are mounted, so that in use the speed of the relative movement of the two confronting surfaces that define the bearing clearance is less than the speed of relative movement of the bearing members themselves. This reduces the power losses due to shearing effects within the thin film of fluid continuously passing through the bearing clearance in contact with these confronting surfaces. The invention applies particularly to rotary bearings of journal and end-thrust type, in which the moving lands may be ring-shaped units, mounted for rotation about the bearing axis and supported by relatively friction-free bearings-for instance gas bearings-on the bearing member in which the bearing recess is formed.
