ABSTRACT:
A fluid bearing assembly includes a first element and a second element which moves relative to the first element along a predetermined path. The first element has a first surface which is opposite to a second surface of the second element. A recess is defined at least in either one of the first or second surfaces for maintaining therein a quantity of fluid, such as air and liquid. Also provided is a heater inside of the recess so that the fluid inside of the recess is heated to expand in volume, thereby pressurizing the fluid to establish alignment between the first and second elements. Such a fluid bearing assembly may be applied not only for the rotary type bearing assembly, but also for the linear motion type bearing assembly.
