ABSTRACT:
An air bearing sample spinner for use in an NMR probe has a first air bearing established between frusto-conical mating surfaces of rotor and stator to provide levitation and rotation. A cylindrical portion projects from the rotor into a similar coaxial cylindrical portion of the stator where a journal bearing is provided for centering of the rotor in the stator housing.
