Jul 13, 2002 - The ABEC rating system uses odd numbers, ranging from 1 to 9. The higher the number, the tighter the tolerance of the bearing, and thus, the 

The ABEC rating system includes grades 1,3,5,7, and 9. The higher the ABEC rating, the tighter the tolerances are, making the bearing a more precision part

There are five classes from largest to smallest tolerances: 1, 3, 5, 7, 9. The higher ABEC classes provide better precision, efficiency, and the possibility of greater 

Abec-9 has been the highest grade in bearing industry. The Abec 9 rollerblade bearing can be applied to any harsh conditions with high speed requirements

The Bullseye ABEC 9 bearing is best for very fast speeds and high precision. For example, if you wanted to achieve high speeds in a downhill style skate, these
