There are a number of factors covered by the abec bearings grades, but to give you an idea we will just examine one of these factors-the eccentricity (out of roundness) of the track in the inner ring. For an ABEC 1 (lowest grade ) bearing, the maximum eccentricity allowable is 0.0075 mm (0.000295"). This is quite precise-more than precise enough for skates and skateboards. The figures for other grades are:


ABEC3: 0.005 mm (0.000197")

ABEC5: 0.0035 mm (0.000138")

ABEC7: 0.0025 mm (0.000098")
