The invention relates to a self-monitoring ball bearing, and belongs to the field of bearing monitoring and new energy. A partition plate with a circuit board and a sensor divides an outer circle intoa left cavity and a right cavity, and an inner circle is arranged in the right cavity through a large ball. Two groups of piezoelectric vibrators are arranged in the left cavity through screws, pressing rings and shock insulators. Outer rings of the shock insulators are connected with inner rings with clamping grooves through rib plates. A half shaft is arranged at one end of a pendulum shaft. Alarge plummer block and a small plummer block are arranged at the other end of the pendulum shaft. An inclination angle exists between the half shaft and the axis of the small plummer block. The intersection point of the half shaft and the axis of the small plummer block is located on the cross section of the half shaft where the symmetry center of an outer raceway is located. The large plummer block and the small plummer
