They were developed by the American Bearing Manufacturers Association (ABMA). Five tolerance classes have been distinguished: 1, 3, 5, 7, and 9 (from highest to lowest). This means that the higher the number, the more precisely the bearing is manufactured. Individual bearing parameters are achieved first by segregating the balls, inner and outer rings, and finally by using a lubricant.In fact, it's difficult to say that an ABEC 9 bearing is generally better than one with the number 5. An ABEC5 bearing was designed for a specific application in a given model of inline skates (usually recreational skating), and for example, type 3 bearings are primarily offered in children's inline skates. ABEC5 is a choice for beginner skaters who prioritize durability over speed. ABEC7 is the perfect balance between durability and relatively high speed. ABEC9 bearings represent almost the highest level of technology, intended for top-of-the-line models, and are usually chosen by those who value impeccable quality.
