System, apparatus and method for estimating remaining useful life of at least one bearing

A computer-implemented method for estimating remaining useful life of at least one bearing, the method comprising:

• receiving, by a processing unit, a request for analyzing a defect in the bearing from a source, wherein the request includes operational data associated with the bearing,
• determining vibration spectrum of the at least one bearing from the received operational data;
• monitoring an impact of the defect on the at least one bearing over a period of time based on the determined frequency spectrum;
• determining one or more characteristic values from the vibration spectrum for which the impact of the defect on the bearing is above a threshold range;
• determining an impact force during an operation of the at least one bearing based on the determined one or more characteristic values and one or more parameters obtained from a virtual bearing model;
• determining a remaining useful life of the bearing based on the determined impact force during the time period;
• and
• generating a notification indicating the remaining useful life of the bearing on an output device.
