The iron spectrum analysis skill is a unique method suitable for judging and guessing the rolling fatigue. The lubricating oil of the rolling bearing is extracted as a part of the oil sample; the high gradient magnetic field is used to make the solid foreign matter contained in the oil sample flowing through the magnetic field; The large fraction is deposited on the glass sheet; the shape, size, color and raw material of the foreign particles can be investigated; thus the type of wear can be clearly identified.

The iron spectrum skill is in principle to determine the strong magnet such as steel. As the main policy; but also for foreign metals such as copper, non-ferrous metals, sand, organic matter and sealing debris, there is also a good judgment.
When the steel sample exhibits spherical spherical particles with a diameter of 1 to 5 Î¼m; the bearing must have fatigue microcracks at the beginning; when the oil sample exhibits a length-to-thickness ratio of 10:1 fatigue-peeling particles; and the length is greater than 10 Î¼m; bearing The normal fatigue wear in Central Africa has now begun; when the length is greater than 100Î¼m; the bearing is now ineffective.
The third type of fatigue debris is a fatigued sheet having a length to thickness ratio of 30:1; its length is between 20 and 50 Î¼m; the sheet tends to be empty. When present at the beginning of fatigue; the number of such sheets is significantly increased; Together with spherical particles as a marker of fatigue.
Ferrographs are generally divided into three types: analytical iron spectrometer; direct reading iron spectrometer and online iron spectrometer.
