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 

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 

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
