SKF bearings exhibit during its use in a strong regularity, and repeatability is very good. Normal quality stainless steel bearings when you start using, vibration and noise are relatively small, but some scattered spectrum amplitude are small, may be due to some defect in the manufacturing process, such as surface glitch caused.
        After the campaign period of time, to maintain a certain level of vibration and noise, the spectrum is a single, there is only one or two multiplier. Rarely occurs more than three times the frequency spectrum, stainless steel bearing condition is very stable, into the stable working period.
        After continuing to run into the post-use, SKF bearing vibration and noise begins to increase, sometimes different sound, but the vibration increases as the initial failure.
        First, the bearing element spectral analysis found abnormal concentrations of non-ferrous metals and iron spectrum appears in a number of sub-micron wear particles of non-ferrous metals; lubricants excessive moisture, excessive acid value, indicating that the tile surface SKF bearing corrosion.
        Secondly, bearing spectral analysis found abnormal concentrations of iron, iron spectrum, there are many sub-micron wear particles of iron components, lubricants water and acid value exception indicating tile bearing back due to fretting and wear.
        Third, the stainless steel bearing iron spectrum in the presence of abrasive cutting temper color or black iron oxide particles, metal surface, the journal bearing surface showed to be strained.
        Fourth, SKF Bearings iron spectrum were found to have cutting abrasive, non-ferrous metals and abrasive component, indicating that the bearing surface strain.
        Fifth, bearing spectral analysis found abnormal concentrations of iron, iron spectrum, there are a number of sub-micron particles of iron components, lubricants excessive moisture or excessive acid value, indicating that the needle bearing journal surface corrosion.
        SKF now know the cause of bearing failure, and that our main attention to these aspects, that stainless steel bearing life naturally on the president of the.
        When the outside durum material into the bearing, and pressure between the body and the raceway, the surface indentations formed. In addition, an excessive impact load can also make contact with the surface of local plastic deformation which pits are formed. SKF bearings when stationary, even if the load is small, due to the vibration of the surrounding environment will be evenly distributed pits formed in the raceway.
        When SKF bearing seal is not good, so that dust or particulate matter entering the bearing, or poor lubrication, the contact surface will cause more severe abrasion or wear, and stainless steel bearing vibration and noise increases.
