Q:I'm buying a new skateboard with complete trucks, wheels and abec 3 bearings.I just wanted to know if it is any difference to Abec 5, 7, 9 ??: ABEC ratings have nothing to do with speed or anything else to do with skateboards or skates. Actually, the higher ratings could be slower. The ABEC rating is for smaller gaps between the parts so that they do not vibrate in high speed machines. You won't be into the range that the specs relate to until you are over 200 mph. Some of the top makers of skate bearings (Zero Drag, Twin Cam, Bones) have designed their best bearings to have larger gaps in critical areas to roll faster but the gaps mean that they don't even meet the ABEC 1 standard. The lubricant used in a bearing will have more effect on it's speed than anything else. Light oil is fast but you need to add it more often. Grease will last for years but is sluggish if more than a tiny amount is used. Gels are in between. Unless you have extremely different bearings (like oil vs over greased), your wheels will have a much larger effect on your speed than the bearings.

Q:So do skateboard bearings fit into scooter wheels?: Yeah they should, skateboard and Rollerblade bearings are the exact same bearings, assuming razor scooters take Rollerblade wheels, then yes they would. Go for the swiss bearings....you'll be floating!!! lol

Q:This is a technical question depending small losses for example in clean room applications (every particle matters...): I assume you have tried shielded bearings, where the grease is contained inside covers that prevent its loss? Or possibly you do not have the funds to replace the bearings? Etc. I do not know the size of your pump/motor or whatever the bearing is on. I will tell you I have seen in an industrial setting on what I would call a small pump, they actually put a bag around the bearing housing to catch grease. Of course, the shaft ended at the housing so the bag did not have to come in contact with the rotating assembly. You could probably get more useful answers if you re-ask your question describing the size and physical configuration of the bearings and their housing.

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:rollerblades btwi got water on them and then they were total slow, ive done the white spirit to get rid of all the grease and lubed them with 3in1 oil, will they be fast againsbtw, any1 who says wd40 im gonna report you because that completely ***** your wheels.cheers: Probably not. Water tends to ruin bearings. Once rust starts, it can='t be stopped without damaging the bearings. Get new ones. Try Bones Reds. 2 boxes for recreational skates, one for aggressive.

Q:ok so i have a customized haro f1 bmx bike and im look to buy new bearings for my cranks or bottom bracket w.e. you call it.im not sure what kind i need.american? mid? euro? or spanish?: Does the bike still have it's original HARO splined bottom bracket axle? If so, it will have loose bearings in a race that run in the outer cups at each end of the axle. There's not much you can change about those other than maybe some heavier duty ones if you're hard on the bike. Best bottom brackets have sealed bearings and tend to run smoother for longer. Not sure what type the HARO has, as they were originally made in the US, I'd guess they have an American BB. Euro's are best in my opinion. If you need to alter the internal diameter of the BB shell, you can buy adaptor kits.

Q:i have a 1994 toyota pick-up with the 3.0 engine 4wd. the main bearings went out and i called to see how much they would cost and the guy asked me what kind they were. and i had no idea. anyideas?: There are different size bearings, they vary depending upon the wear of the crankshaft and if it has been previously resurfaced. All the bearings will have just about the same cost. You will have to disassemble the engine and check the clearances with plastigauge or micrometer to know which bearing sizes you need.

Q:All bearings are designed with tolerances to allow the moving parts to move, but how are wear limits determined? In other words, after time, the components will start to wear out and the bearing will become looser. Looking at some aircraft maintencance manuals, they provide wear limits in the radial and axial directions. But how are these wear limitis determined? Is there a particular calculation that is done or is an arbitruary number chosen?: General ideas only. In the case of journal bearings with forced lubrication (oil pressure), increasing clearance results in oil pressure drop. Ideally, journal bearings hold an oil film which supports the rotating shaft and minimizes metal/metal contact. Automobile engines run for hundreds of thousands of miles using this strategy. Radial ball bearings will tolerate excess clearance (depending on the load) but the shafts they support often will not. In cases where oil seals are used, excess shaft play damages seals and permits leaking. In the case of motor or pump shafts, bearing slack permits rotor/stator contact or impeller/involute contact. Rotating masses are never perfectly balanced or axially aligned. Bearing slack multiplies unbalanced force and consequent load.

Q:im confuse... so, i know how to remove the wheels and bearings and stuff. i wanna know what to use. my friend told me to use acetone but idk what acetone is... could someone tell me? and i also wanna know how to clean it. do i just pour the acetone in a bowl and put the bearings in? or do i have to remove the sheild of the bearings before i put it in? could someone help please?if you can tell me what acetone is and where i can get it. is it in nail polish remover? thanks: www.okorder /

Q:is the lucky or red bone bearings the best for making your skateboard go faster: Reds are your best bet. Although i would recomend getting bones swiss bearing. They may be more expensive, but they are well worth it. With bones, abec doesn't matter. Abec was designed for bearings for the industrial use. Although abec 7s arw good, bones dont have abec because they dont need it. They are further designed to resist the hazards that skateboarding may have rather than most bearings.
