Abstract
A door suspension system comprises a horizontally suspended ferromagnetic shaft; a nonmagnetic bracket comprising a bracket cylinder for enclosing a linear bearing and an attached bracket hanger plate for securing a door panel; a nonmagnetic cylindrical linear bearing sized to slide into the bracket cylinder and over the shaft; at least two spaced bores in the upper surface of the bracket cylinder; at least two spaced bores in the upper surface of the cylindrical linear bearing arranged so as to align with the spaced bores in the bracket cylinder; a cylindrical permanent magnet positioned in at least one of the spaced bores of the bracket cylinder; and a ferromagnetic armature to complete the magnetic circuit through the shaft and the magnet or magnets.
