Q:06 raptor 350 rear axle bearings?
If the wheels didn't want to turn right after the new bearings were put in, they didn't go in right. Riding it like that was stupid (sorry, it was). The bearings will need to be replaced again, with new seals. And don't forget the grease. Hopefully no other damage was caused.
Q:how tight should skateboard bearings be?
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:beginner skateboard bearings?
For a beginner you should just stick with the ones the board comes with
Q:97 Prelude. What happens when the bearings and drive shaft go bad? How long before I have to replace?
Very unusual for front wheel bearing to fail. Why did you say drive shaft earlier? The car has CV axles that act like drive shafts. If one fails, you are going to have to have a tow. Jack up the car on one side then the other. Look for a shaft that goes to the wheel from the trans axle. There should be 2 boots per axle. If the boots crack they will be covered with dirt and grease. This will eventually precipitate the universal joint within the boot to fail and break. On wheel bearings, if they are bad, you may or may not be able to drive the car until one of them seizes. Then you will need a tow. Maybe you should get used to using public transportation. Either way, you are going to have to get your problem fixed. It's like my wife. Her Honda needs both CV axles, a timing chain and ball joints on both sides. I want her to drive my 89 Pontiac until I can fix her Honda, but she complains that she doesn't like the gas mileage on the Pontiac. I told her, what does it matter? She has three things that are eventually going to drop her in the middle of the freeway and maybe getting run over by a semi truck. I plan on sabotaging her Honda so she if forced to use the Pontiac. Don't get yourself stuck out on a limb. Either park the Honda and get on public transportation or get it fixed. By the way, my wife's Honda Accord has 450,000 miles on it.
Q:Do cars use cup and cone bearings or is it specific to bicycles? (and other questions)?
Not so long ago, racers- particularly velodrome racers- built their hubs using very light machine oil instead of grease and ran the bearings slightly loose. This was called trackmens slack inasmush as using the hubs like this offered almost no resistance. Unfortunately, one race like this and the hubs required rebuilding including replacement of balls, cups, and cones. Whenever I can, I still spec cup and cone hubs on bikes I design and build most of my own bikes with cup and cone hubs. EDIT: I wanted to add that ball, radial, and needle bearings which are used for just about everything now in some fashion were first developed for the bicycle. Before the bicycle, bearings were made of wood, leather, and bronze. The bronze ones were called babbett bearings.. similar to sleeve bearings today... but not exactly.
Q:Can i clean my Skateboard Bearings with Hair Clipper oil?
Clipper Oil
Q:2003 Suzuki Ozark 250 bearings help?
is almost the same, the only diff is how the wheel is opened up,,, i believe they seal the bearings so you will haft to press them out i think,, if not then then its the same,,, ive only came across 2 types of 4wheelers that had to do that,, they were polarius models that floated on the water,,, now lookin at yours its the same as a car,,, after removing the wheel you take off the spindle ( for a car its called a rotor) then pick out the bearing clean out the grease add new grease, and pack the bearings with grease befor you put it in,, the more grease the better lol
Q:Any one want to give me some pointers on how to tighten down front wheel bearings on a 1987 GMC v-1500 4x4?
G.M. recommends several different methods, but the most simple is the best. Your pick-up has disc brakes, and this is a factor in the procedure. After cleaning and packing the bearings, and assembling the hub and rotor assembly, with the appropriate socket tighten the FIRST retaining nut until it stops. You will feel it bottom out. Spin the hub/rotor assembly several times and tighten again until it bottoms out. Do NOT apply pre-load. Merely tight is sufficient. At this point, controversy arises. Some will advise to install the lock ring and outer nut at this position. It isn't wrong, it is just that if you back the nut off approximately 1/6th to 1/3rd of a turn, and then secure it with the lock and outer nut, the bearings will run just a BIT cooler,and the fact that the rotor isn't held rigid will allow the pads a bit longer life, and it won't affect either safety or alignment. Good Luck
Q:Wheel Hub or Bearings??
Front or rear? The rear has hubs that are sealed for life now (except for RWD, AWD and 4WD). They do go out. On FWD (and 4WD) the front has bearings, and these also go bad. They are also sealed for life bearings, but these are serviced by pressing the old bearings out and pressing new ones in. There is the off chance that it is a loose nut on the axle by the way. Or a bad ball joint. But I am assuming that you know that it is the wheel moving and not the whole rear member.
Q:Can someone explain and demonstrate the use of magnetic bearings?
A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. They are in service in such industrial applications as electric power generation, petroleum refining, machine tool operation and natural gas pipelines. They are also used in the Zippe-type centrifuge [1] used for uranium enrichment. Magnetic bearings are used in turbomolecular pumps where oil-lubricated bearings are a source of contamination. Magnetic bearings support the highest speeds of any kind of bearing; they have no known maximum relative speed.
