- Q:On skateboard bearings what's the ABEC letters mean?
- Go to Wikipedia for more info
- Q:i just bought a new set of bearings and put some lubrication on 'em. but when i put them in my wheels and spun them they make a little grinding noise. i don't know if this is normal or not but any help would be appreciated.
- What kind of lubrication did you use? It sounds crazy, but with some bearings, if you used motor oil (as in 10w/40 or whatever) you can actually ruin your bearings. I killed a set of tensor bearings this way a while back. Same thing too, bad grinding noise and they kinda seized up a little too. They'd still roll, but not very well at all. Once I figured out that plain old OIL can be bad (which I still can't believe), I've just been sticking with Bones Speed Cream because I don't want to have to think about it too much.
- Q:i have china reds and they and really slow like i spin it and it stops...i got it from a friend who used his steam cleaner to steam clean the bearings anyone know how to make them faster and/or clean them using stuff i can find around house like someone told me to use vinegar so help me out plz.................thanks
- Ammonia is really a great cleaner you might give that a try.
- Q:I just bought the sector 9 bambino 26.5 and I was wondering what would be better for it. Im trying to decide between the bones swiss labyrinth would bones super swiss 6. What would be better for my board-thanks.
- Bones Swiss Labyrinth. With the extra $4 you pay you will cruise longer. I have some on a 27 inch Gravity and they are great.
- Q:For a skateboard. Which are better?
- Bones Reds try and get ceramic bearings keep maintenance on them every month and don't worry about ABEC ratings cause it counts for nothing and you will have bearings for at least a year or two depending on where and how you skate.
- Q:ok I took apart my bearings, cleaned the shields with water, put about 2 drops of lube in each after letting the bearings sit in a 50% alcohol solution for 10 minutes, put it all back together after drying off the stuff and lubing it. Just rode it today and it seems that the bearngs are making noise.... is this normal???
- the proper way to clean bearing is to soak them in karosene and then pack them w lube/ grease the alchol proally dried em out
- Q:when im parked on a flat surface my tires sit perfectly straight and look completely normal, then when i park on a small incline the tires and wheels spread t outward really bad, it turns and drives fine, it has 35 inch tires and 16.5 wheels and ive heard 4wd can cause it to do that but if anyone can give me some info thatd be AMAZING..lol-thanks
- What kind of vehicle is it? Is it coil over, torsion bar, twin I beam, how many miles: dont gremlin hunt, get some deinitive answers. I would have it inspected for upper and lower ball joints, control arm bushings, drag and center links, idler and pitman arms, and the integrity of the radial runout of the hub to bearing assembly! Remember, putting bigger tires on vehicles that were never intended for them, tend to cause some pretty unusual circumstances! Especially when a lot of the factory geometry is now different! Hope this helps! Best Luck
- Q:here's a link to rush hybrid bearings
- dude you know what you need, rush all weather bearings. i got them, and 2 days ago, my board fell in the POOL!!!!!! the whole board sunk! my board is ok amazingly, it was in their for almost like, 2 minutes(its longer then you think), and my bearings are still workin brand new.no rust or anythings. their water and rust proof, their awsome too!!!! but get the rush hybrids if you dont get the ones i just told you about lol. sorry for the whole story ****.
- Q:from fast forward?
- General pro skateboards have element bearings. But most of the time, the company the skateboard is from will probably have their brand bearing. Most pros have element bearings though.
- Q:I'm getting some ABEC 5 bearings, but I don't know if I need them sealed or shielded. Right now I'm a beginner so I'm just cruising with the occasional hill if that makes a difference in what I need.
- Get ones with removable shields. If the bearings are sealed, you can't clean or lube them, so you throw them out and get new ones.
