How can we improve?
Skateboard bearings abec-1 have lowest precision grade among all skateboard bearings. But it doesn’t mean that these abec 1 608zz bearing can’t be used. Firstly we should know what is abec-1. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA).
I believe that it is difficult for skateboards lovers to have the patience to study. So as to abec 1 rollerblade bearing, our conclusion is that it is the most common bearing and is applied to most occasions which are not highly demanded, and its price isn’t very high.
