Skateboard bearings are one of the most important components. They are mostly made of steel and oiled with solid grease or oil. You can choose according to your favorite brand or the ABEC standard, which indicates the accuracy of the processing of the balls inside. In our assortment, however, you will also find Bones bearings, which are manufactured without the ABEC standard, given that they consider it outdated. They replaced this standard with the term "Skate-rated", which better covers the quality demands that skateboarding places on bearings.
