Bearing oscillation on bearing failure is obvious, for example: spalling, indentation, rust, cracks, wear, etc. will be reflected in the bearing oscillation detection, so by using special bearing oscillation measurement equipment (frequency analyzer and oscillator, etc.) can measure the size of the oscillation, through the frequency dispersion can be inferred from the specific circumstances of abnormal oscillation, the measured value due to the conditions of use of the bearing or sensor device orientation The measured values vary according to the conditions of use of the bearing or the location of the sensor installation, and so on, and therefore require prior analysis and comparison of the measured values of each machine to determine the standard bearing.

Usually the temperature of the bearing rises slowly at the beginning of the work and reaches a stable condition after 1 to 2 hours. The normal temperature of the bearing varies according to the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation are not suitable, the bearing temperature will rise sharply and abnormally high temperature will appear, when it is necessary to stop the machine and adopt the necessary preventive measures.

Smooth to rolling bearing fatigue life and conflict, wear, temperature rise, vibration and other important impact, no normal smooth, the bearing can not work. Analysis of the causes of bearing damage shows that about 40% of bearing damage is related to poor smoothness. Therefore, the outstanding smoothness of INA bearings is a useful measure to reduce bearing conflicts and wear.

In addition, the smoothness of the bearing also plays a role in heat dissipation, rust prevention, sealing and shock mitigation. To ensure that the slick cannot expire, the selection should be correct. Harvester bearing smooth points oil smooth and grease smooth two, large models gear box oil smooth selection with GL-5 80W90 gear oil; grease smooth generally with molybdenum disulfide lithium smooth grease, smooth torque increaser stepless variable speed lower device must use Mobil XHP222 or better grease smooth
