ABEC-9 CARBON Nils Extreme bearings are made of high-quality carbon steel, ensuring excellent hardness and durability. They are characterized by the lowest rolling resistance, which translates into the highest speeds in the American Annular Bearing Engineering Committee (ABEC) standard. A key parameter of this bearing is eccentricity, or the roundness of the inner ring, which is just 0.0012 mm. This bearing is designed for roller skates, skateboards, and scooters.
