unfounded There are several legends on the bearings. concern is very common to have a higher abec to roll faster. The truth is that the larger the number of abec bearings have less friction, resulting in speed, smoothness and continuity, but these benefits never get to enjoy in a meaningful way unless rodemos at speeds of 180 km hour or more.
In contrast the high abec are more fragile and require more maintenance. Are much more precise and rigorous, less tolerant of mistakes and workmanship are used much more fragile materials.
For freestyle is important that the bearings are shock resistant and tolerant of punishment so that a ABEC 3 and we are well served and will last us a lot more.
For slalom, downhill, speed and we can do well like a bearing softer and often, as a abec 5 or 7.
A abec 9 or 11 only use the speed in competition. Its duration is shorter and committed.
The fact that sometimes we can find in high ABECS series skates is just a matter of making them attractive to the buyer candid.
Depending on the type of contact that exists between the parts, the bearing can be sliding or linear and rotary. The rotatable element can be used in bearing manufacturing, they can be balls, rollers or needles.
rotary motion bearings, in the sense of effort that supports, there are axial, radial and axial-radial. The manufacture of ball bearings is that technology occupies a special place, given the procedures for obtaining the perfect roundness of the ball. The largest manufacturer of bearings used such a vacuum for this purpose. The material is treated abrasive absolute vacuum chambers. The Swedish steel manufacturer of high-friction parts in machines, have managed to bring technology into outer space for the final treatment of the ball, avoiding the gravity effect, to achieve the desired sphericity.
bearings or ball bearings are called shooting in some English-speaking countries. More on bearings
