A piesewise linear spring and damper model considering contact stiffness and restitution coefficient between bearing and case is introduced to analyze subharmonic resonances and the selfexcited oscillation of the impact model in the former report. By applying Harmonic Balance Method (HBM) to the equivalent nonlinear spring and damper model, the periodic solution is analyzed in the speed range of 1/2 order subharmonic resonance speed. As the results, the entrainment of 1/2 order
