I just bought new skateboard bearings, but there so slow. I have bought the same brand before but the It was way way faster, but on the one I bought before said 5 on the pack and on the new pack of the slow ones it says 7. ....the guy that sold it to me said the 7 ones would be faster???????
Indy bearings take a long time to break in. They use a thicker gel lube. You might want to clean them and lube with a light skate bearing lube. ABEC ratings have absolutely nothing to do with speed. It is a measure of tolerance and it only applies to applications where the rotational speed is over 10K RPM.
