Q: What bearings are best for skateboards?


A: Commonly used skateboard bearing models are 608Z-5 bearing and 608Z-7. The biggest difference between -5 and -7 is their precision level. The former is a bearing type commonly used in skateboards, and the latter has a higher precision, which can meet the requirements of practitioners for skateboarding speed.

The type of skateboard bearing is generally expressed by ABEC. Generally, the model used is 608,608. There is also a difference in bearing hardness. According to the hardness of the skateboard bearing, it is divided into -5 and -7. Generally, the models used in skateboards are 608Z. -5, if the speed requirements of the skateboard are relatively high, 608Z-7 can also be used. The biggest difference between -5 and -7 is their precision level.

ECABEC is a standard for classifying precision bearings. Generally, there are 9 types from 1 to 9. The higher the model value of the bearing, the higher the precision level used to manufacture the bearing, and the higher the price of the bearing. In fact, the precision of skateboard bearings is not as high as that of yo-yo. Therefore, skateboards are generally equipped with eight bearings, which can reduce the friction coefficient of the skateboard during the sliding process, thereby ensuring that the skateboard can slide normally.
