Abstract
A superconducting bearing unit compring a permanent magnet mounted to a rotating shaft and a superconducting body mounted on the inner periphery of a housing surrounding the shaft, the superconducting member being adapted to be cooled with the rotating shaft moved upwards until it attains a superconducting condition, so that the rotating shaft is supported in use in a balanced condition between the weight of the rotating shaft, etc. and a pinning force caused by the permanent magnet and the superconducting member.
