The invention discloses an intelligent monitoring ceramic bearing which comprises a ceramic bearing body, an intelligent monitoring module and a self-power-supply module installed on the bearing body. The ceramic bearing comprises a rotary inner ring and a fixed outer ring; the intelligent monitoring module comprises a shell and a monitoring integrated circuit board, and the shell is coaxially and fixedly connected with the fixed outer ring; a limiting clamping groove used for fixing a stator module in the self-powered module in the circumferential direction is formed in the shell, and the limiting clamping groove makes axial contact with the monitoring integrated circuit board. The self-powered module comprises a stator module, a retainer, a rotor limiting ring and a rotor module; and the retainer is fixed with the rotating inner ring through the embedded teeth, so that the retainer and the rotating inner ring have the same rotating speed. On the premise that the overall structure of the bearing is not damag
