Bones bearings chooses not to put an ABEC rating on their bearings because it doesn’t make sense on a skateboard bearing. ABEC ratings measure the tolerance of a bearing, so a higher ABEC rating means it can spin much faster in a machine, but this is not actually helpful when ranking skateboard bearings. Since George Powell created these are the world’s first bearings designed specifically for skateboarding, he decided to leave off any mention of ABEC rating and instead calls his bearings Skate Rated.
