1. A computer-implemented method for estimating remaining useful life of a bearing, the computer-implemented method comprising:
receiving, by a processing unit, a request for analyzing a defect in the bearing from a source, wherein the request comprises operational data associated with the bearing;
monitoring an impact of the defect on the bearing over a period of time;
determining a time period during which the impact of the defect on the bearing is higher than a threshold range using a machine learning model, the time period being indicative of a time duration in which the bearing enters and leaves the defect;
computing a severity of the impact associated with the defect during the time period by computing a defect size corresponding to the defect based on a duration of the time period;
determining, using a virtual model of the bearing, a remaining useful life of the bearing based on the severity and the operational data during the time period, wherein the virtual model is generated based on simulation data, experimental data, mathematical data, or any combination thereof associated with a plurality of other bearings; and
generating a notification indicating the remaining useful life of the bearing on an output device.
