2) Bearing tolerance levels are divided into 2, 4, 5, 6, 6X and 0 levels, a total of 6 levels, from high to low, the code is/PZ, / P4 ‘/ PS, / P6, / P6X and/PO. Among the tolerance classes, class 6X is only suitable for tapered roller bearings; Class 0 is a common class and is not indicated in the wheel bearing code.
3) Commonly used bearing radial clearance series is divided into 1 group, 2 groups, 0 groups, 3 groups, 4 groups and 5 groups, a total of 6 groups, radial clearance from small to large. Group o clearance is the commonly used clearance group, which is not marked in the bearing code, and the remaining clearance groups are respectively represented by/CI, / CZ, / C3, / C4, / CS in the bearing code.
