20090263062 | Active Preload Control for Rolling Element Bearings - A method and apparatus for controlling the preload of duplex rolling element bearings systems under various temperatures is described. A spacer or a plurality of spacers may be located adjacent to the rings of the duplex rolling element bearings. The spacer or spacers may be heated or cooled to increase or decrease the axial dimension of the spacer or spacers.
