Well, if they are just noisy or run rough, you can try to clean them out and relube them.
But if they've gotten too loose and wobbly, you'll have to replace them.
Clean & lube can be a bit difficult, so some prefer simply to replace.
Yes. When they make noise when you spin the wheel. Also if you see dirt in your wheels you should replace them. Also they only cost a few bucks so what the heck. You mine as well replace them. I like to because i go faster. i ve been Skateboarding for 6 yrs. now
Depends on what you mean by "good", how you skate, and how much time/money you want to spend on maintaining your stuff.
"Fast" bearings usually don't last very long. They tend to be sensitive to getting dirt/grit inside, which cause them to wear out fast. Not a good thing if you ride outside unless you're OK with replacing them often.
Sometimes it's overall better to use a poorer but cheaper bearing. You can afford to replace them more often, so you get to ride on "new" bearings more often.
And a new cheaper bearing is probably better than an expensive, worn-out bearing.
you can buy rims at a local skate shop
I'd buy new bearings but that's just me
Almost. I've seen a horribly cheap toy skateboard once that didn't have bearings, only a plastic center to the wheel. But apart from that, any time you buy a complete skateboard it'll come with bearings.
Linear Bearings are self-lubricating. WalMart is a store that sells many items online. You can purchase linear bearings from WalMart and they will have it delivered to the store for free or to your home for a nominal cost.
no, buy from your local independent skateboard shop
yes but soak your bearings in motor ol for 10 min
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.
For a kids push scooter, there are 2 bearings per wheel, 2 wheels per scooter. 4 bearings total. If you buy a pack of 8 for a skateboard, you will have 2 sets.
You cant buy an electric skateboard, but you can buy an electric scooter. If you want an electric skateboard your going to have to make it yourself. Good luck!
