A fluid dynamic bearing system having a first conical bearing and a second conical bearing working in opposition to the first conical bearing, wherein the two conical bearings are disposed along a stationary shaft, wherein the first and the second conical bearing each comprises a bearing cone disposed on the shaft having bearing surfaces as well as a conical counter bearing disposed in a rotor component that are separated from one another by a bearing gap filled with a bearing fluid, wherein the bearing gap has a first open end that is sealed by a first sealing gap partially filled with bearing fluid, wherein the bearing fluid in the sealing gap forms a fluid meniscus. The sealing gap is bounded by sealing surfaces of the bearing cone and associated sealing surfaces of the rotor component, wherein the smallest radius R1 of the sealing surfaces of the rotor component is larger than the largest outer radius R2 of the bearing cone and larger than the greatest possible distance R3 of the fluid meniscus from the rotational axis.
