Rolling bearing level of accuracy and precision of the rolling bearing main dimensional accuracy and rotation accuracy.
Precision grade has been standardized, divided into a level 0, 6 x, 6, 5, 4, 2 levels of six grades.
Since a level 0, in turn, improve accuracy, for general purpose level 0 is enough, but in used are shown in table 1 conditions or situations, needs to be level 5 or higher precision.
Although more accuracy grade is set by the ISO standards as a benchmark, but its name is different in the national standard.
Rolling bearing level of accuracy and dimensional accuracy,
Associated with the axis and shell installation project)
