Bearing systems, such as magnetic bearings, are widely used today in a variety of applications. All bearing systems are, however, subject to failure. Therefore, backup bearing systems are often utilized in conjunction with a main bearing system in order to provide backup to the main bearings if they should fail. The backup bearing system for the re-centering of magnetic bearings includes a first conical member disposed about an axis and having at least one bearing disposed substantially therein; a second conical member spaced from the first conical member and disposed about the axis, the second conical member having at least one bearing disposed substantially therein; and an actuator assembly spaced from the second conical member and bearing in a first or operative position. The actuator assembly acts to move the second conical member and bearings disposed therein between the first, operative position where the backup bearing system is operating to re-center the magnetic bearings, to a second, inoperative position, when the magnetic bearings are once again operating.
