Abstract
A self-aligning bearing assembly utilizing PDC buttons for forming opposing circumferential arrays of bearing surfaces, is particularly suitable for use in a fluid environment, such as being immersed in flowing water when supporting the rotor of a hydroelectric turbine. One bearing surface is supported for rotation with the rotor. The opposing bearing surface is supported by a spherical joint in a stationary housing. When the rotor is subjected to hydraulic loading, the opposing bearing surface can be tilted to self-align with the rotor axis.
