Summary
      The invention relates to a radial bearing can automatically monitor the amount ofbearing wear monitoring device, installed on a shaft in the bearing is equivalent to thepermanent magnet generator rotor ring, magnetic ring in the corresponding upper and lower body location to install two probes, probe generated within the induction coilEMF, the probe and the composition of the gap magnetic sensors, shaft sinking when the bearings wear, the magnetic gap with the smaller probe, potential changes inducedby the changing magnification drive wear indicating instrument display, the probeproduced induced current as the probe amplifier drive current. The utility model can be applied in a variety of mechanical devices, especially for sealed magnetic drive pump.
