Abstract:

Deposits found in life-tested bearing assemblies were analyzed by electron spectroscopy for chemical analysis, by ion microprobe mass spectrometry, by infrared spectroscopy and by solvent analyses. These analyses showed the deposits to be one or more of the following compounds ferric oxide, naphthenic acid, lead naphthenate, Apiezon C and alkali metal oxides or sulfates. On one of the bearings, the residue on the balls was of a different composition than that found in the raceways. Author
