Abstract

A support assembly (14) as shown in the figure for supporting a rotating shaft relative (10) to a structure (70) in which a first magnetized member (90) is attached to the shaft for rotation therewith, a support member (20) is connected to the structure and at least one damper member (60) connects the support member to a second magnetized member (70) for supporting the second magnetized member (70) in a portion relative to the first magnetized member (90). The respective magnetic fields of the first and second magnetized members are such that radial deflective movement of the shaft, and therefore the first magnetized member (90), causes corresponding radial movement of the second magnetized member (70) which is dampened by the damping member (60).
