general bearing question

[Christopher Krupansky]

hello i was wondering what "abec" stands for and what they mean by abec 3,5, or 7. and i was also wondering what bearings are good for speed. thanks bye

The term that's generally associated with bearings is "ABEC". ABEC is the acronym for Annular Bearing Engineering Council, the standards committee of the Anti-Friction Bearing Manufacturers Association (an industry group) that determines the requirements for each level of bearing precision. The higher the ABEC number, the stricter the manufacturing tolerances and the more precisely the bearing is made.

Keep in mind that ABEC ratings are more relevant to machines running at something like 40,000 rpm's and not necessarily applicable to skating.

Bones Swiss (and also Rockin Ron's, I think) aren't ABEC rated at all and are excellent bearings for skateboard applications.
