ABEC-5 bearings ABEC-5 bearings  are a simple, proven bearing design that guarantees high durability and maintenance-free driving. Brake A brake in inline skates is an absolutely essential element for most beginner skaters. Thanks to it, even people with no experience can quickly master the skill of braking while skating. What is the ABEC standard? ABEC is a set of tolerance standards for the production of ball bearings. They were developed by the American Bearing Manufacturers Association (ABMA). Five tolerance classes have been distinguished: 1, 3, 5, 7 and 9 (from the largest to the smallest tolerance). The higher the number, the more precisely the bearing is made. Individual bearing parameters are achieved first by segregating the balls, inner and outer rings, and finally by using a lubricant. In principle, it is difficult to say that the ABEC 9 bearing is generally better than the one with the number 5. The ABEC5 bearing was created with a specific application in a given model of roller skates in mind (usually recreational skating), and for example type 3 bearings are mainly offered in children's roller skates, then ABEC5 is a proposal for beginner skaters who value durability much more than speed. ABEC7 is the perfect optimum between durability and relatively high speed. ABEC9 bearings are almost the highest technological shelf, they are designed for the highest models and are usually chosen by people who value impeccable quality.   Size converter: EURO SIZEINSERT LENGTH [CM]US SIZE 34 21 4 35 22 5 36 23 6 36.5 23.5 6.5 37 24 7 38 24.5 7.5 39 25 8 39.5 25.5 8.5 40 26 9 40.5 26.5 9.5 41.5 27 10 42 27.5 10.5 42.5 28 11 Additional Materials Manufacturer's website Catalog K2 YouTube Channel
