The paper discusses some possibility of the arising damp vibrations under inertia input for asymmetric rotor supported in the cylindrical slide bearing lubricated by electro fluid. It is shown that the effect of the electric field on the individual bearings junction makes it possible to achieve similar vibrations for both journals bearing although with strong asymmetry. The phenomenon discussed that increasing intensity of the electric field causes a reduction of the forced vibration but the self - excitation threshold moves in direction to the lower rotation speed.
