Yes, most bearings are the industrial standard of 8mm unless you have special longboard trucks, most notably Bear 1052's or 1045's or Bear Smokeys, these trucks run 10mm but are not very common. If you can take wheels off with the same wrench on both trucks, then they have the same size bearings.
All skateboard bearings will fit ANY sized skateboard wheel because the bearing hole is designed to be the same in all wheels.
no
no there are many different sizes to the scooter trolley bars.
Same basic design/different group size.
What is the size of scooter smiff
Yes you can if the battery is the same size
Answer:Outdoor wheels are more rubbery and grippy and indoors are hard plastic
If its the same as the atm50a it isCR7HSA
60mm tall x 36mm wide with an axle/bearing assembly that is centered within the wheel, not offset like a skateboard wheel.
Need to know if 2 wheel or 4 wheel drive for the front. Either way, there is no nut on the back axles.
Well, to be technical about this answer, ball bearings are NOT used on roller skates or skateboards. This technology went out in 1975. Since then, the 608 size precision bearing has been the standard. As for why this size was chosen: the 608 size, which has a 22mm outer circumference size, was the closest size to the existing cup size of the previous technology, which actually used ball bearings on the inner and outer axle holes in the wheels, along with cups and nuts to keep the bearings in place. That cup size was not standard, but was based on the size of the wheel itself. As for why bearings are used in the first place: precision bearings are by far the most technologically simple, effective way for any modern round wheel, gear, propeller, turbine, disk drive, or anything else you can think of, to spin.
