ABEC means Annular Bearing Engineering Committee. It is the representation of the precision of the bearing via the closeness of a skateboard’s moving parts. Presently, there are only five ABEC levels for skateboards bearing: ABEC 1, 3, 5, 7, and 9. The ABEC-7 being one of the most balanced and suitable for kid’s skateboard while ABEC-9 is regarded as the fastest. However, the speed of a skateboard does not solely depend on the ABEC level. The speed depends on other factors such as load, wheel, and other materials. ABEC is just a representation of the precision of the bearing and can contribute to the speed of a skateboard if matched with the right materials.
