Vibration on the bearing damage can be quite sensitive, peel, indentation, rust, crack, wear etc, will be show in measurement of the bearing vibration . So, by the use of the special bearing vibration measurement device (frequency analyzer, etc) can measure the size of the vibration, through the frequency points not that abnormal specific situation. The measurement of numerical of bearing conditions of use or sensor installation position and different, so need to every machine in advance measured value analysis is made then the judgment standard.

We then look at the effect of temperature on the bearing.

With high temperature often said bearing is already in the abnormal situation. High temperature is bad for bearing lubricant. Sometimes the bearing can be on the overheating bearing lubricant. In more than 125 ℃ bearing temperature even reduce bearing life . The reason caused by high temperature bearings include: lubrication is insufficient or excessive lubrication, lubricant. Contains impurities, load is too large, bearing loss loop, the gap is insufficient, and oil seal of high friction produced, and so on.

So the continuity of monitoring bearing temperature is necessary, whether measurement bearing itself or other important parts. If it was in operation condition under the condition of invariable, any change in temperature can be expressed already failure.

 
Bearing temperature measurement can be regularly with the help of the thermometer, such as SKF digital thermometer, can accurate measurement temperature and in ℃ or Fahrenheit temperature will display unit. The importance of the bearing means that when damage, can cause equipment down, so this kind of bearing should be the best temperature probe.
