WebOct 30, 2024 · Bearing faults are categorized into four stages, based on the types of frequencies produced by rolling elements impacting defects in the inner or outer races. At the first stage, small pits appear in the bearing race and impacts of rolling elements appear at ultrasonic frequencies in a spectrum. Stage 1 is still considered normal operation. WebNov 3, 2016 · 1. Fatigue. Stress over time, which is fatigue failure, is the right reason why bearings should eventually stop rotating. This cause of failure is different than wear. Fatigue failure is related to the stress the bearing is subjected to over time. Fatigue failures in bearings typically originate sub-surface and eventually will propagate to the ...
