The radial-axial superconducting bearing prototype was designed, fabricated and tested. The presented HTS hearing design provides stable suspension of the rotor in axial and radial directions. Magnet bearing system contains the rotor with 7 HTS disks of total mass 90 g and stator with annular permanent NdFeB magnets. Load and stiffness characteristics are measured. Maximal load capacity, in axial direction — 85 H, in radial — 190 H, axial stiffness — 102 H/mm, radial stiffness — 165 H/mm, magnet air gap — 1 mm. Overall bearing dimensions: diameter is 130 mm, thickness — 30 mm, and mass — 1,8 kg.
