The ABEC rating is how ball bearings are rated. The ABEC rating is from 1-9. The grades are 1,3,5,7, and 9.
 
The higher the ABEC rating, the tighter the manufacturing tolerances. The higher the tolerance, indicates a more precisely manufactured part. High precision and small tolerances are required for bearings to function at very high RPM.
