   Accuracy class
    Angular contact ball bearings accuracy class include dimensional tolerance and rotation precision. From low to high precision expressed as P0 (ordinary), P6 (P6X), P5, P4, P2. In addition, European and American brands also used P3, P7, P9 indicates accuracy class, P3 is equivalent to ISO and JIS standards P6 level, P7 equivalent level P4, P9 is equivalent to P2 level.
   nsk bearing vibration
   nsk bearing vibration of the bearing damage is very sensitive, such as peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration measuring device (frequency analyzer, etc.) measurable the size of the vibration frequency points can not be inferred unusual circumstances. The measured values due to the conditions of use or the sensor mounting position of the bearing, etc., and thus requires prior measurement of each machine will be determined after the analysis and comparison criteria.
