IDEAS AND HYPOTHESES ON PLAIN-BEARING FAILURES
The paper discusses plain-bearing defects and establishes hypotheses about correlations for plain-bearing failures. The low wear rates at continuous removal of material -- following a pronounced running-in wear -- can be explained only by foreign matter included in the lubricant or by material fatiguing. Tests made with engines that suffered of a critical oil shortage revealed that a bearing seizure is not developed within fractions of a second, provided the bearing as such is in perfect condition. Great loads and insufficient cooling shorten the critical period until failure caused by heat. Normally, bearing defects that occur in practice are caused by foreign matter.
