Use WD-40 i use it on my scooter bearings and they are the same as skateboard bearings as well if you want them to go faster soak them in the stuff for 2 days and then dry with a towel
yeah, theyre for skateboard and scooters
yes there the same bearings for every skateboard
a skateboard is less eco friendly because it use trees to make a skateboard there for the bike is more eco friendly
FKD bearings
a skateboard has 8 bearings. 2 bearings inside each wheel facing opposite ways inside each wheel
