The design of magnetic bearing of disk type on the base of high-temperature superconductors (HTS) has been proposed. The prototype of rotor system with two HTS bearings has been constructed and manufactured. According to the selected arrangement the HTS elements of 180 g in mass provide stable suspension of the rotor of 3,6 kg in mass in operating gap 0,8 mm. The maximal load capability of the bearing in the radial direction amount to 220 N, in axial - 150 N. The ratio of the load capability to the mass of superconductors is more than 120. The maximum rotation frequency is 14500 rpm.
