- Q: does cold or hot temperatures cause skate bearings or any bearing to spin faster?
- heat will cause the bearings to expand and cause more friction. Colder weather will cause the bearing to shrink and then there will be less friction; however, if it's lubricated, the heat will cause the lubricant to be more fluid and causeing the bearings to move quicker and the cold weather will be the opposite
- Q: okay so i just wanted to know where i could get the bearing cage retainer( holds the bb's ) i came across a site but i want to find something thats cheaper in price but still last a good or long amount of time, and also they have the bb's but they dont say how much come with the purchase and dont know which brand is good.so if you know anything about which is a good brand please help me out.i want ones that spin good and good cage retainers.please give me the sites if you know any or where i can get them.oh and for skateboards just in case anyone missed that the first time.and dont write me saying just purchase them at a skate shop.i already have bearings in my tool box that need to be cleaned i just want to get some cage retainers and the right sized bb's.thanks.
- Ok, okorder /
- Q: What does ABEC for skateboard bearings mean?
- ABEC stands for Annular Bearing Engineering Council and it is a rating of how good bearings are. Basically the higher the number after ABEC-, the better the bearing is supposed to be. The scale goes ABEC-1, ABEC-3, ABEC-5, ABEC-7 and ABEC-9. Bones Bearings (Swiss, Ceramic) are Skate Rated and are basically better than most of the bearings rated on the ABEC scale.
- Q: which skateboard bearings are the best?under the conditions of durability and overall performance, which ones have you used that you think are the best?
- get okorder / (click the link and scroll down to the bottom where it says Reviews and click one) good luck man, hope you find what your looking for.
- Q: Well, I was wondering: do all skateboard bearings have 2 sides? I looked at abec 7 or 8 bearings and they do not seem to have 2 sides? How do I know which side should i grease? Also, does abec bearings have a metal/rubber covering on one side? Thanks, if you can answer all these questions, i will give you best answer. Don't say, Get bone swiss bearings! They're better! I know they are, but I'm asking about abec 7 bearings. Thanks.
- most of them have two sides. I believe that abec 7 bearings have two sides but i am not sure. google abec 7 bearings and that should give you the answer
- Q: I have 8 bearings like any other skateboard. all 8 are crappy because my bro takes it out in the rain. Damn. And one of the 8 is all smashed up(long story). So im riding to school and when at fast speed it starts to wobble ALOT even on flat smooth ground. Would buying new red bone bearings fix this?thanks
- get bones reds and try not to leave ur boards in the rain
- Q: I've cleaned my 5000-C but the spool doesn't let line on unless you pull even with everything turned to the lowest. Im trying to figure out if the inside has bearing because the bar in the spool doesn't come out at all. Is this normal or is it suppose to come out once you remove the white gear? Need help asap... I've got two other Ambassadeurs and would love to use the 5000-C as another go to reel. Thanks!!!
- the only bearings on the 5000C are the ones at the ends of the spool shaft. one external, underneath the tension adjustment cap and the other inside the opposite sideplate, held in place by a small metal clip. *the only BALL bearings. other turning contact points have bushings which to a nit picker, are, in fact, bearings.
- Q: We took our 1996 ford aerostar van into the mechanic the other day and he said it needs new wheel bearings on the front left tire and something like the axle assembly done, he said the housing was cracked right open on both sides and they need to be replaced and he said all up it would cost $1200, seems like alot of money, I know its not a great explanation but if you no wat parts im talking about, do you think this price is right? Thanks
- Seems an average cost. Driveshafts are not cheap and bearings have to be pressed into place. There would be a significant labour charge too.
- Q: ^ also how should they sound when they roll and what should i use to lubricate my bones red bearings
- You will want to make sure that your bearings are placed correct in your wheels and when you tighten the bolts down do not tighten too much. you wil actually want a tiny bit of slack in between your nuts and bearings as funny as that sounds. this will allow your wheels to roll more freely. If bearings are new the should sound fairly smooth but they take a while to break in. New Bone Reds are fast enough to where you wont need any lubricant but if you really must dont use any crap like wd40. actually get something worth your while
- Q: will to spend around $30 bucks
- i culdnt agree more with ilatina mafia....BUY BONES REDS you will not regret it, best bearings by far
