The bearings are usually silver looking discs that are in the wheels. They can be any color, but since they are usually metal, the most common color is silver. When you assemble a skateboard, you have to press the bearings into the wheels before you put the wheels onto the trucks. This is what gives you speed, not the wheels. Bearins are rated usually ABEC 1 - 7 (except for bones). Basically, the higher the number the faster they will be, but also the price.
yeah, theyre for skateboard and scooters
FKD bearings
depending on your bearings
a skateboard has 8 bearings. 2 bearings inside each wheel facing opposite ways inside each wheel
pop them out of the wheel
no
Probably not considering they're roller blade bearings
Bearings are used to let the wheels spin freely and with minimal drag.
yupp yupp
All skateboard bearings will fit ANY sized skateboard wheel because the bearing hole is designed to be the same in all wheels.
Two bearings hold each wheel of a skateboard to the axle. These bearings are generally made out of steel. On some more expensive models, they may be made from silicon nitride, which is a ceramic.
ya it's possible. you'll just get your bearings screwed up.
