FIELD: instrument industry.
SUBSTANCE: bearing comprises two pairs of coaxial ring permanent magnets, which are mounted on the stator and combined in pair in the direction of the magnetic induction flux by means of two ring magnetic circuits, and high-temperature superconductors. The magnetic flux that is entrained by the superconductors centers the rotor. The superconductors are secured to the rotor which is set in the space between the permanent magnets. The surfaces of the permanent magnets that face the magnetic space are provided with ring plates made of the magnetically soft material, e.g., Permalloy or electrical-sheet steel.
EFFECT: decreased friction.
