bearings for skates
Bearings for in-line skates, skateboards and scooters are offered mainly in size 608 (diameter 22mm). Accuracy of bearings is marked with two standards - ABEC and ILQ together with certain number. The higher the number the more accurate the bearings are. ABEC7 or ILQ9 are then more accurate than ABEC5 or ILQ 5. But overall quality of bearings is determined by many factors which are usually not provided by manufacturers. The most appropriate indicator is price or experience gained by other skaters.
