• Though several analysis of the MHD journal bearing have been reported, they are all based on magnetic fields of extreme difficulties in practical construction. This paper presents a theoretical analysis of a relatively practical case with the magnetic field perpendicular and the external electric current parallel, respectively, to its journal axis. The pressure distributions are obtained numerically and from these, the load-carrying capacity and the frictional torque are determined. Tha results obtained are compared with those of the ordinary and other types of MHD journal bearings. It is shown that the load-carrying capacity increases by the application of the magnetic and electric fields, whereas the torque is hardly affected. The load-carrying capacity is found to increase more with an increase of the external electric current than that of the magnetic field intensity. The static stiffness of this MHD journal bearing is shown to be almost of the same magnitude as that of the ordinary journal bearing.
