Q:What are skateboard bearings?
there iside the wheel thats what lets it roll
Q:How do I know my front wheel bearings need to be replaced. I have a 1997 Dodge Dakota with 99,500 miles.?
You normally just check the bearings when you do the brakes. Then you clean and repack them. If you get front wheel looseness or noise, then you jack it up and check for bearing play, or hear grinding.
Q:what would cause the cam bearings to melt in my car?
lack of oil or over heating. only help is rebuild
Q:Speed up my skate wheels/bearings?
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:Could this have caused my alternator bearings to fail?
Jennifer. You didn't hurt the alternator bearings by driving the car to the automotive store. Without the serpentine belt, the alternator and water-pump doesn't turn. Without the water-pump spinning is the reason the coolant temperature got hot. The alternator bearings were stiff or noisy before the belt spun off. In fact, that might have caused the belt to spin off. Too bad there isn't an automotive electrical shop or private mechanic nearby who couldn't split the alternator and slide on new bearings and brushes. The alternator will be as good as new! If you're pushed into a corner and it's necessary to purchase an new re-manufactured alternator call around for the best price with the *best lifetime warranty. Let me know how you make out.
Q:Condenser fan motor bearings are bad on my home ac unit how can I tell?
Fan Motor Bearings
Q:is this good for my skateboard bearings?
I think this stuff should be fine, though I don't know if it will help speed up your bearings. I've used WD40 on my bearings before and it didn't seem to hurt, so you should be okay to put this stuff on. I would also recommend that you check in with a local skate shop and ask what they would consider before you put it on just in case.
Q:Skateboarding- What are trucks, bearings, and hardware?
Trucks are the metal axles and plates that mount to the board. They come in different sizes depending on what type of riding you plan on doing- the longer the axle the less turning radius you'll have. Bearing are small discs that contain tiny metal ball (bearings) that allow you wheels to spin freely once they are mounted on the truck-there are 2 bearing rings for each wheel (inside outside) . These also come in all types and generally the more expensive the bearings the more spin/speed you'll get. Hardware merely refers to the bolts nuts that hold the trucks to the board. These also come in all sorts of lengths and brands, but really they are mostly all the same. and don't forget some of the most important gear for a noob will be protective gear, helmet pads etc. Have Fun !
Q:What material used in bearings? Describe the composition of elements.?
Sn % Sb % Cu % PbApplications 933.53.5-Light and medium IC engine big end bearings 8610.53.5-Light and medium IC engine main bearings 80113.06General purpose heavy bearings (lead increases plasticity) 601028.51.5Heavy duty marine engine bearings, electrical machines 40101.548.5Low cost, general purpose, medium duty bearings
Q:What are exaust bearings and what do they do?
the only sort of bearings I can think of that would be part of the exhaust would be in a car with a turbocharger.
