   Accuracy class
    Angular contact ball bearings accuracy class include dimensional tolerance and rotation precision. Accuracy from low to high is expressed as P0 (general), P6 (P6X), P5, P4, P2. In addition, European and American brands also use P3, P7, P9 indicates accuracy class, P3 is equivalent to ISO and JIS standards P6 level, P7 equivalent level P4, P9 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 measurements, so that through the use of special bearing vibration measurement device (frequency analyzer, etc.) measurable size of the vibration, the frequency points can not be inferred unusual circumstances. The measured values due to the use of conditions or bearing sensor installation location, etc., and thus requires prior to each machine measurements were determined after analysis and comparison criteria.
