- Q: can i use rubbing acholhol?
- Use Speed Cream from Swiss (who make skateboard bearings) -- it's like 3 bucks for a little bottle.
- Q: Hey my friend gave me his older bearing which where speed demons and I was thinking about switching my stock 5 abec bearing which of these bearings are better for long boarding and why
- ABEC ratings are meaningless unless you are worried about small amounts of vibration over 200 mph. Really, it is a standard about vibration in high speed industrial machines. Even an ABEC 1 bearing is much better than the precision grade bearings that were used in the early skates and boards so going to ABEC was a big step up. Then the marketing people realized that they could put bigger numbers on things and the race was on. In theory, a given manufacurer puts more care into making the higher number bearings than they do the lower number bearing, but that doesn't mean that their high number bearing might not be better than a low number bearing from a better maker. In reality, the best bearing companies make non-ABEC bearings as their best ones because the smaller gaps in the high number bearings can slow you down. They put close tolerances where they need them and open up space where it can be done. They also use better grades of metal or ceramics. Within typical bearings, you will see a bigger difference due to the lubricant (and how much is used) that the bearing has in it. Oil will be faster but requires new lube more often. Grease lasts longer but is slower (especially if too much is used). Gels are in between.
- Q: I was cleaning my bearings and the balls and the inner ring came out how do i fix this please help me
- I have found that impossible to put back in, trying to do that with skateboard bearings. I would rather recommend replacing the bearings with a new set. Since the balls have broken out of the race way, it will not perform too good. Either grinding unevenly against the walls of the race way, or not spinning at all.
- Q: i'm trying to make my bearings as fast as possible by cleaning them constantly with simple tissue paper...turns out it does not work to good. there are no skate shops in my area,(southeast texas) so i would like to know if there are any type of cleanser/lube product that i could find in my counter or at a wall-mart. thank you.rules:don't say google it.
- Clean with denatured alcohol - available at hardware stores Lube with Tri-Flow - bike shops and some hardware stores.
- Q: Hey i have a few questions about a pair of bearings...Ok are speed demon bearings any could? I know luckys are best but i was just wandering.Also have u guys ever heard of quikies? they were on my board i bought complete at a shop. Its a good complete toy machine with venture lows and shorties hardy. so i was jw.thanx
- Speed demon bearings are pretty good, bones reds or swiss are better. lucky's are not the best, the best in the same price range would be bones reds. Quickies are pretty bad bearings, they seem to spin fast once there broken in but there not polished enough to be very fast.
- Q: I have a 1990 240sx that has an Sr20det motor. I was driving home one day and about 15 minutes from home my engine started sounding like marbles. When I got home after only 15 minutes of it sounding like that I turned it off and removed the oil pan and there were definitely pieces of rod bearing in it. My question is, after driving for only 15 minutes home, could it have more damage than just the bearings?
- definately. your rods are probably bad or bent pistons may have scored the walls at an angle cuz the rods wernt straight due to the bearings,ect. time for a total rebuild or another engine.
- Q: Do rear wheel drive cars have rear wheel bearings?
- Of course. Even front wheel drive cars have rear wheel bearings.
- Q: It kinda makes a humming sound from the front end
- Ball bearings?? There are no ball bearings in the front end of a Ford Explorer, or any other car for that matter. Most cars use tapered roller(drum)bearings. They usually run 10-25$ per side, plus 5-15$ for new seals to put around them. Grease will be about 10$ for a can of good stuff. Do it yourself and save some money on the labor.
- Q: I had found out bones reds are one of the most best bearings for the money, and lots of mates have them so I bought some bones red's from Trademe (the New Zealand version of ebay) and they were real and all. as soon as I got them I rode them all around. but after about a week they were worse than my abec 3's. So I changed Back to them. While I was at the skate park People were saying that bones reds just need wearing into. so I cleaned them by soaking them in turps then putting speed cream on them. I have been skating heaps this month. but still not beta...???So any advice or help of what im doing wrong would be appreciated
- Check to make the shields aren't dented. The bearings need to be installed with the shields out. When you clean them take the shields off and use denatured alcohol. Only use 2 drops of speed cream per bearing. Any more and it will slow you down
- Q: what can i use 2 clean longboard/skateboard bearings besides acetone?
- Your toung.
