Abstract
Passive load balancing in a fluid bearing for a rotational device is provided using disclosed devices, systems, and methods. In particular, fluid bearing apparatus may include an outer member with an inner member disposed concentrically within the outer member. A fluid inlet may provide fluid communication with a surrounding space between the inner and outer members. A bearing may be connected to the inner member and may extend into the surrounding space. The apparatus may also include a piston located in the surrounding space between the bearing and the fluid inlet. A supporting fluid is located between the piston and a surface of the bearing to transmit force from the piston to the bearing.
