I have been told that the lower the rating the better and vice versa. I've finally had the brilliant idea to ask the question on the almost all knowing internet. Your advice would be appreciated and considered. thanks!
its the higher the better
i've got been using Black Panther Swiss bearings in a pair boards for some years. they have been sturdy and supply sturdy speed, adequate to do grinds interior the 9ft end of the pool. The ABEC score has little to do with speed. It merely pertains to tolerances in manufacture and use in extreme speed equipment. It has not something to do with the suitability of a bearing for skateboarding. it relatively is why maximum extreme-end bearings are actually not ABEC rated, as they are designed especially for skateboards.
ABEC ratings are irrelevant to skateboarding. A higher number indicates better tolerance in the bearings. It does not take into consideration overall quality of the bearing, nor the ability to take side loading, which is common in skating. The rating is only useful for applications where the bearing spins in excess of 20,000 RPM. If you look, high-end bearings do not indicate ABEC ratings. It is just a marketing tactic.
