A dynamic model of a rotor system with hydrodynamic plain 
bearings in which account has been taken of the actually existing 
phenomenon of the circular anisotropy of the rigidity of hydrodynamic 
plain bearings has been proposed. The operation of the rotor system 
has been modeled with the use of uniformity distributed sequences 
and the region of states of the system representing a set of instantaneous 
positions of the center of the end rotor surface by which the accuracy 
of its rotation is evaluated has been obtained.
