PCT No. PCT/GB95/00955 Sec. 371 Date Oct. 25, 1996 Sec. 102(e) Date Oct. 25, 1996 PCT Filed Apr. 26, 1995 PCT Pub. No. WO95/29346 PCT Pub. Date Jan. 21, 1995A hydrodynamic fluid film bearing in which a plurality of circumferentially spaced bearing elements are provided, defining areas of support for the rotating part of the bearing. At least some of the bearing elements are adjustable during operation to vary lubrication conditions in the fluid film. The bearing elements are of sufficiently high stiffness that the position of the entire bearing surface of each element is essentially independent of the pressure in the fluid film encountered during operation. The bearing allows complete control of the lubrication conditions and can be adjusted for optimum performance over a wide range of speed and load.
