Q:what bearings are faster??
hard to tell, I bet they are the same if you broke them in. It can take months of constant skating to break in a set of abec bearings. You never know what you're going to get with abec rated bearings because that rating doesn't mean anything for skate bearings only swiss does. Use some speed cream and break them in and you'll have some fast bearings.
Q:Is it true that you don't need to clean roadbike wheel bearings and it is very hard to do so?
Depending on what hubs you have the bearings may be easy or difficult to service. The easiest are ball and cone bearings. They have either loose or caged bearings that all you have to do is to remove the cones and the axle for access. Clean out the gunk, regrease, and reassemble. If your bike is from Sports Authority, that is probably the style you have. (Do they even sell a cassette tool? Really?) When you adjust the cones and jamb nuts one has to have a lot of practice to set the tension on the bearing properly. You want the point of no play, yet no drag. The jamb nuts must be tight enough so the bearing doesn't either loosen or bind in service. A good pair of Park Tools cone wrenches are in order. Probably a 13/15 cone wrench. The more difficult and type that should be left to a professional are sealed cartridge bearings. They need much less service than ball and cone. Many bearing manufacturers recommend leaving them alone until it is time to replace them. The bearing has to be pressed out, the seal pried off carefully removed, clean and regrease the bearings, reinsert the seal, then press the bearing back in place. Cartridge bearings are usually on more expensive wheel sets. The third type are hubs with seals with cone and ball bearings. You have to remove and reinstall seals in the process of disassembly and assembly.
Q:does a 1991 mazda 626 have front wheel bearings?
Of course it does. ALL wheels have bearings, no matter what make or model of vehicle you have. Even wheelbarrows need bearings in the wheel. The possible exceptions are the single ball type wheels that have a hollow sleeve in the centre as opposed to a roller or pin type bearing as is the norm. Hope this helps.
Q:What are the fastest longboard bearings?
This Site Might Help You. RE: What are the fastest longboard bearings? I Have a longboard but its not that speedy and i want to know which bearings to buy
Q:does gasoline make ur bearings faster?
We used to use gasoline to clean bearings. There are better and much safer cleaners out there now. You must grease the bearings before using them. They will fail very quickly if you don't use the proper grease.
Q:Can the wrong transmission fluid effect ball bearings?
Q:2004 Ford Taurus DISC BRAKES has anyone replaced the REAR bearings?
You should be able to tap the bearings out with a hammer and drift. If you use a brass drift it will be less likely to scratch the housings. You use a large socket to install the new bearings. Grease the bearing liberally first.The socket should bear only on the outer race and you carefully tap it into place. The new bearing may have a relieved edge to facilitate entry and the usual rule is that the writing on the bearing is the edge that faces you. If they are taper bearings you tighten them to hand tight then back off a quarter turn to obtain working clearance. This clearance disappears when the bearing gets hot in use. It would be advisable to buy the Haynes manual for the car as this will guide you through the whole procedure step by step.
Q:Mineral spirits or Acetone to clean my Bones Reds Bearings?
No bro! NEVER! EVER! Use WD-40! Maybe just a 5 sec dip BUT NEVER USE WD 40 ON BEARINGS! It'll eat right through it! Use maybe acetone.. its less acid but is still a bit hard.. I usually clean mine by rubbing them with tissue, then put some oil on the tissue and slightly pass it throught.. not to get the liquid stuck in between..
Q:ABEC 3 skateboard bearings question?
Reflex Bearings
Q:which climate cause skateboard bearings to spin faster in the heat or in cold climate?Does heat cause bearings
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
