Abstract : This report documents the work performed by MTI under contract to Strategic Defense Initiative Organization to develop the technology of Superconducting Bearings. This work, had been supported by NASA and DARPA in addition to SDIO. As a result of this work, MTI had developed a passive superconducting bearing that is used to levitate relatively heavy rotors. It used this bearing to levitate a 7 lb rotor and spin at speeds of up to 12,000 rpm. The success of this effort indicates that the superconducting bearings have potential for transition from a mere laboratory curiosity to a functional bearing component in a wider range of practical applications such as cryoturbopumps, miniature cryocoolers and magnetic refrigerators. In addition, MTI had investigated several configurations of using superconductors to support loads along a single axis. The effort was directed to identify a specific configuration that offers a very high stiffness.
