This bearing is one of a handful of maintenance-intensive components originally identified for condition-based maintenance proof of principle.
WebMotor bearings were seeded with faults using electro-discharge machining (EDM). Faults ranging from 0.007 inches in diameter to 0.040 inches in diameter were introduced separately at the inner raceway, rolling element (i.e. ball) and outer raceway.
