A rotary drum dryer is supported by magnetic non-contact bearings rather than by rollers or wheels which are normally used to support a rotary drum cylinder. A plurality of rare earth permanent magnets are positioned on the outside surface of the cylindrical dryer to form at least two external annular rings. One U-shaped semi-circular channel supported with a cradle have similar rare earth permanent magnets positioned at selected locations on the inside curvature thereof with the open end facing upward and disposed below in alignment with and spaced apart from each one of the at least two annular rings of magnets supporting the on the cylindrical dryer. The like pole magnets affixed to the surface of the cylinder repel the like pole magnets facing them disposed in the U-channels of the cradle causing the cylinder to levitate above and spaced apart a selected distance from the cradle.
