Aiming at the problems about super high -speed micro ball bearings unable to reach working speed,the wear failure of bearings caused by resonance of rotor system during super high speed operation,and bearing speed down caused by cage operation instability,the additional elastic support and flexible cage material is used.The dynamic sim-ulation and experiment analysis prove that the simulation analysis model for bearings is correct,and the measures are effective and feasible.
