Bearing Failure Analysis - Agkits

Engine Bearing Failure Analysis. Engine bearings depend on a film of oil to keep shaft and bearing surfaces separated (figure A). Bearings fail when the oil film breaks down or when the bearing is overloaded. The oil film is generated by shaft rotation (figure B). At rest, the shaft and bearing are in contact. On start up the shaft rubs the bearing briefly. Running, the shaft pulls oil from ...
