Bearing the level of how?

The precision of the bearing, mainly divided into the dimensional accuracy and rotation accuracy. Precision grade has been standardized, divided into P0, P6, P5, P4, P2 grade five levels.
Since a level 0, in turn, improve accuracy, for general purpose level 0 is enough, but when used in special conditions or situations, needs to be level 5 or higher precision.
China bearing before old code accuracy class code
National standards are according to ISO standards, are generally consistent with ISO, individual in ISO standard strictly. Divided into dimensional accuracy and precision rotating accuracy. Divided into a level 0, 6 x, 6, 5, 4, grade 2.
China bearing old code standard is before: G level (level 0), E (6), D (level 5), C (4), B (level 2). The current code generally USES the German DIN standards.
P0 level (level 0), P6 level (level 6), P5 class (level 5), P4 level (level 4), P2 level (level 2).
Standard level P0, reaction on the bearing type is omitted, only the P6 grade or above level P6, level code didn't appear in models of bearing.
For example: 6205 and 6205 / P5, of which 6205 precision grade level is P0, but is omitted. This caused people, P0 level is a precision bearing impression.
In addition, all kinds of precision bearing in addition to the difference on the processing technology, and the difference in value.
