Q: Needle roller bearing is also called cam bearing?
Seems not.Cam bearings are also called roller bearings and bolt bearings.
Q: are these above, just consumable type things ,that need replacing after time, how many miles for each generally speaking would they need to get replacedwhat are signs that track rod ends have excessive playwhat are signs that wheel bearings have excessive play, and what exactly do they do
its really tuff to say it just depends on the Quality of the part
Q: How do you CHANGE WHEEL BEARINGS on a Suzuki Quad? I can see the outside one (there are two per side) but I am not sure how to remove and reinstall them. Are there special tools needed? What are the steps?THANKS!
use a long skinny punch to drive the old bearings out from the opposite side... then use a socket of the proper diameter and a hammer to carefully drive the new bearings and seals(when applicable)into place....I recommend buying the manual for your particular machine, they can save you a lot of money and headaches...
Q: How do I tell if my ford ranger wheel bearings are shot? ?
you can either wash the grease off in a solvent tank and inspect the bearings for pits and discolered ends where the hardened material has worn off (also how much movement in the bearing race itself. Or do what I do on unknown mileage bearings toss them out and buy a good made in USA set. The made in china cheapo bearings are soft core with a hardened shell. And at some point they start to disintegrate and take out all the other bearings too. A good set of bearings are not that expensive and always buy a new grease seal
Q: OK, so our ball bearings on our 2003 Hyundai tib went out pretty bad!! We bought new ones from auto zone and replaced them, within a week the bearings were destroyed again, so we brought our car to the base auto shop. The told us the bearings we bought were bad. They replaced them and we just spent $405 for them to replace them, put a new tire on and to do an alignment. We picked up the car monday! It is now only Thursday, 3 days later and the car seems to be making a grinding sound like it was before the 1st time the bearings went out. What are the odds we got 2 bad bearings? We do know that eventually the axle needs to be replaced but 2 mechanics have told us that it will be months before it NEEDS to be done! I just don't understand. The car is in fair condition and worth around 3,9500 as a trade in. We will prob. just trade it in soon bc it's not worth it. Has anyone else had this problem!??
They probably didn't pack them if they are the rear bearings, the fronts are BCE-type and are sealed requiring no lubricant. If they guarantee their work take it back so they can make it right. If you are shopping for a new car don't bother trading it in, take out a craigslist ad and sell it cheap as a mechanic's special needing work. Hyundais turn into junk after they're paid for, don't buy another one. Look for a Toyota.
Q: what types of bearings are used and what are their application?i need some good information as im finding it hard to do some research!thanks in advance!
Tapered okorder too.
Q: does anybody know what the best liquid to use for cleaning bearings?
I don't really know but i use rubbing alcohol. I would have alcohol in a cup and put my bearings in then with my top hand cover the top and shake a little. Then take em out and roll em until they feel like they're new again(sorry for bad english im mexican)
Q: i heard people said it makes it stronger. but i dont know if they meant only to put the wheels inside to make the wheels stronger. because i dont want to break my bearings.thankz.
yeah i put my wheels in the freezer every time i get a new pair, i would recomend putting the bearings in but when i freeze my wheels i freeze them in a solid block of ice for a month. i dont know if it works but ill take any advantage i can get

Q: Can someone explain and demonstrate the use of magnetic bearings + magnetic variation and ways of determining directions without a compass.
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.
