IKO bearings in use during the show a strong regularity, and is very good repeatability. Normal quality imported bearings (Rolling) start using the vibration and noise are relatively small, but the spectrum and some scattered amplitude are small, may be due to some defect in the manufacturing process, such as surface burrs.
Movement after a period of vibration and noise to maintain a certain level, the spectrum is very simple, only the first, second multiplier. Very rare three times above the working frequency spectrum, bearing very stable, into a stable period.
Continue to run into the use of late, the IKO bearing vibration and noise begins to increase, sometimes appeared tone, but the change of vibration increases more slowly, at this time, bearing the kurtosis values suddenly reaches a certain value. We believe that, IKO bearings, expressed as the initial failure.
At this time, the IKO imports bearing closely monitored, and pay close attention to the change. Thereafter, the bearing kurtosis values began declining rapidly, and close to the normal vibration and noise significantly increased its growth significantly began to accelerate when the vibration exceeds the vibration standards (such as the ISO 2372 standard), bearing kurtosis value The rapid increase, when both exceed the vibration standards, and kurtosis values above the normal (available kurtosis relative standard), we believe that the bearing has entered the late failure of production, the need for timely maintenance equipment, replacement of the rolling bearing.
IKO bearings showed late failure characteristics to a serious failure (usually the axle bearing damage, burns, sand shelf spallation raceway, bead wear) Time is no more than a week, the greater the capacity of equipment, the faster speed. the shorter the interval. Therefore, the actual IKO bearings fault diagnosis, once found late failure characteristics, should be decisive to determine the bearing fault, as soon as possible overhaul.
