Nonlinear oscillations in connection with magnetohydrodynamic journal and slider bearings are discussed. It is assumed that the externally applied magnetic field is constant and uniform, the applied electric field is uniform but harmonically oscillating. Using electrically conducting fluids as lubricant and applying electric and magnetic fields, it is possible to produce pressure even if the shaft does not rotate and the bearing is fixed. The equations of motion for a rigid shaft supported in short MHD journal bearings are derived and solved numerically. By a similar analysis the slider bearing is examined.
