An improved flexible support (10) for a steady bearing in rotational contact with the surface of a shaft allows the bearing and houseing to substantially track the contact surface of an impeller shaft when the shaft is subject to elastic deflection during operation. The flexible support employs a flexible disk pack (14), which is comprised of a plurality of thin, flexible disc elements in a stacked arrangement. The disk pack (14) is mounted to a suppor t ring (16) and is also mounted to the bearing housing such that the bearing housing and other bearing elements are capable of deflection to substantiall y align with the axis of the impeller shaft when the shaft deflects.
