The ABEC rating of a bearing is determined by
asking these four questions:
1.How close is the bore to 8mm in microns (a micron is one millionth of a
meter)?
2.How close is the outer diameter to 22 in microns?
3.How close is the width to 7mm in microns?
4.What's the rotating accuracy in microns?
Don't worry if that doesn't mean anything to you - I just wanted to include
it in case you're reading this for a paper you might be writing for
school!
ABEC 7
bearings isn't the only way to rate skateboard bearings, by the way. There
is also the International Standards Organization (ISO) system and the [German
National Standards Organization (DIN) system. Here is a chart to help you
compare:
ABEC 1 = ISO 0 (or "normal") = DIN P0
ABEC 3 = ISO Class 6 = DIN P6
ABEC 5 = ISO Class 5 = DIN P5
ABEC 7 = ISO Class 4 = DIN P4
ABEC 9 = ISO Class 2 = DIN P2
It's important to mention that not all skateboard bearings even use the
ABEC rating system. Rockets, Ballistech Missiles and Bones Bearings all use
their own systems to rate their bearings. This might seem fishy, but it's
actually a very good thing. Most bearings used in skateboards were never
designed with skateboarding in mind! These companies have developed and built
their fag bearings specifically for skateboards,
and they get a lot of respect in the skateboard community because of this.
I hope this explains what ABEC means, and that you now have a better
understanding. If you have any questions that weren't covered here, please feel
free to write me and ask!
Daddies has searched far and wide to find a high quality skateboard bearing
for a ridiculously low price! While traveling on the outer edge of the milky way
the DBS crew came across these killer double shielded ABEC 7 bearings. We
quickly mounted these puppies up and took ina
bearings for a spin. All we can say is cosmic baby!
