Q:is there something wrong with the bones swiss black bearings i bought?
Check to see if the bearings are seated correctly in the wheels. If that's not it, check to see if the nuts that hold the wheels on are too tight. If you loosen them a little, the wheels should spin better. You should also have 1 washer on each side of the wheel. This prevents the bearing from touching the truck and slowing it down. How long have you had the bearings? It usually takes a few week before they start to spin their best, once some of the oil they are packaged with dries out a little.
Q:how much does it cost to have wheel bearings replaced?
A tire that is squeaking or any other noise has nothing to do with a wheel bearing. The wheel bearing is in the center of the axle of the vehicle, and is usually lubricated very well, so as to not have a problem with being out of bearing grease. You need to get several opinions/estimates from reliable repair shops before getting any work done
Q:how do i brake in or broke in my bearings for skateboarding?
how to broke in your bearings..another term is to season your bearings.. simplest way is to bomb some hills a few times.or just skate everyday ...this saves a lot of time..the reason you must do this is cos when a new bearing you buy from the local sk8 shop..they roll fast but still not fast enuff..these bearings are machine finished and only quality tested..they are not run in for endurance test..hence they may have some ruff edge even tho they roll smooth on the naked eye.. :D
Q:I have new longboard bearings how do i make them faster?
Go to home depot or something and get some WD-40... is't a metal lubricant that works pretty well.
Q:What is the best skateboard bearings?
It depends on what you like.
Q:2001 Saturn L series: replacement Hub/Bearings mismatch?!?!?!?
This is the correct bearing. Its called a unit bearing and must be pressed in with a hydraulic press. Most front wheel drive cars use this set -up. A little tip: If the driver side is bad it likely the passenger soon to follow ,have them both done at the same time. To save some money remove the hubs from the car yourself.Take them to a shop have the bearings pressed. They should only charge about 35.00 each.
Q:are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?
The ABEC scale isn't very accurate for measuring how fast a board can go, hopefully we will one day get a scale that is accurate. You're Bone Swiss bearings probably do go faster, when you're riding your board, challenge him to a race, either you'll win or you got ripped off.
Q:some good teaching MOTIVATION or VISUAL AID on "BEARINGS" (trigonometry)?
Depending on the age group, one of the resources I use is a print from googlemaps of the school. The students have a route they have to plan around different rooms faculties using bearings distances (scales). Make it as hard / easy / fun as you wish. Or a similar idea using a print of an estuary, with shipwrecks marked so they have to either avoid or hit as they wish. They seem to enjoy the crashing part! Other than that, here are some interactive websites to try: www.mathsonline.co.uk/freesite_to... www.active-maths.co.uk/whiteboard... (bearings is near the bottom of the page) www.10ticks.co.uk/s_gamesAndAct.a... good luck
Q:can i put the skateboard wheels with the bearings inside and then put it in the freezer?
No. It doesn't do anything to help the wheels. If you insist on trying, take the bearings out. If for some reason you insist on keeping those in there too, make sure you haven't clean them recently or have put lubricant or speed cream in there because it will freeze the bearings and probably create more water than you want in there. I don't recommend it at all, all it will do is make your wheels colder. Also I'm not being mean on the if you insists, just you wont know for yourself if you don't try so if you're like me and need to try something even though it probably wont work, I say that. Again though please don't, because this is one of these things I've tried =P
Q:is this maintenance spray good for skateboard bearings?
it may be good for internal bearings it sounds like it's exatally like wd-40 which isn't a good spray for bearings only because it leaves a residue behind that'll collect more dust and dirt and do more harm. You're best to get the silicone sprays like that bearing factory one, I know it costs more but it's a lot better and a can that big would last almost a liftime because it doesn't take much to lube a skateboard bearing, or even 8 of them.
