There are many failure modes of bearings, and the basic failure modes are:
wear (abrasive wear, fatigue wear, adhesive wear, fretting wear) failure, fracture failure, corrosion failure and indentation failure. However, a very common failure form in our daily use of bearings is wear failure.
The structure of the bearing and the use environment are different, which will lead to the diversification of its failure reasons.
The main reasons for these failures are: improper assembly of bearings, poor lubrication, excessive load, shock, vibration, intrusion of abrasives and harmful turbid liquids, excessive or low ambient temperature, and the material of spherical roller bearings. There are some defects, etc.
Due to the complexity of the working conditions, two or more failure mechanisms may act simultaneously, in some cases a single failure mode, and in some cases multiple failure modes.
