Specifications:
Needle Roller Bearings (needle bearing) is a cylindrical roller with roller
bearings, relative to its diameter, roller both thin and long. This is called needle
roller. Despite having a smaller cross-section, has a higher load bearing capacity
equipped with a thin and long needle bearing roller (roller diameter D≤5mm,
L / D≥2.5, L is the length of the roller), so radial structure is compact, its
diameter size and load capacity and other types of bearings, minimum diameter,especially for radial dimensions limited support structure.

- Q:Which skate bearings are the best? Modus ABEC 5, or Bones Reds?
- Bones! Abec ratings are for bearings for machines. Bones doesn't build bearings for machines. They are for wheels. Powell swiss are the fastest bearings you'll ever have.
- Q:I have a sector 9 Cosmic 2 board and one of the bearings messed up. i need to buy spare bearings. i can't find longboard bearings while skateboard bearings r easy to find. r they the same? and whats a good place to buy beartings
- yes they use the same type of bearings and you can find them from your local skate shop or you can try fixing the broken bearing by cleaning it. what i do i put wd-40 and let it run through so all the dirt comes out and they once all the dirt is out you spin the bearing until the wd-40 drys out and then you put speed cream in it. but if you buy new bearings get bones reds.
- Q:can the front bearings be regreased in a oldsmobile alero 2003?
- No they are sealed bearings.If you have a bearing noise the most simple way is to buy a hub/bearing assy.NAPA can get them alot of the time when you got a noise up there its not the bearing,its the axel/C.V. joint.If the boot is ripped open it prabably needs a axel.The bearings don't fail nearly as often as the axels.
- Q:I drive a '98 Dodge Ram, and my bearings just went out for the second time. Should I get a new rotor or just new bearings? And if I need a new rotor, is there anything other than the rotor that I need to install?
- If you didn't change the bearing races when you changed the bearings, you should do that this time. It's what probably caused the last bearings to go out again.
- 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:Ok, so I've been longboarding for a while now and I've recently started doing more downhill stuff on my longboard and I have decided I would like to replace the bearings on my board from steel to ceramic. 1. Because ceramic apparently are much better and faster. 2. I have basically destroyed my steel bearings they are rusty and squeak. I know how to fix them, I've done it a few times and it works, but it's more for speed. I have a Krooked Zig Zagger board and 65mm Zip Zinger wheels. I want to know if you can replace the bearings without replacing the wheels aswell, because the wheels still have a lot of use in them?? Also, I want to join a longboarding crew or team in Adelaide, Australia, but I'm a girl so it's difficult. I know there is an all girls crew in the city, I'm all for ladies longboarding but after researching it I think they just cruise around not much hill bombing, whch is what I'm in to. If you're part of a longboarding crew, would you take a chick??Ohkays ta! xxx lt;3

- Q:what is the advantage and disadvantage of water-lubricated bearings?
- The main advantage of a water cooled bearing is you can use the a portion of the water from the pump discharge to lube the bearings. That way you can always be assured of the lubricating fluid supply and do not have to relay on another pump. Some pumps do use another source, especially if the water being pumped is dirty, but it is still cheap and non-contaminating if some leaks into the pumped fluid. However, water is not always a good lube especially on pumps with high speeds and/or mechanical loads. Water is not very viscous and becomes less so with increased temperature. Even small 3600 rpm pumps will use oil for lubrication. Some large, high pressure pumps will have their own oil pumping and cooling system for the bearings.
- Q:When I turn the wheel (to go around corners) there is a grinding sound from both front wheels... I'm guessing this is wheel bearings...? Can they be repacked or do they need to be replaced. I see new wheel bearings for my truck on Advance Auto for cheap ($13) but I don't know if it is a big job or not.
- If they are making a grinding noise, then it's too late to just repack them. Get new ones.
- Q:Some folks say that using them to go through or under the rubber cover on a tie rod end doesn't get grease into the joint itself. Sound reasonable?Many ball joints these days don't seem to be greasable with them at all -- am I missing something?Can the needles lubricate sealed bearings, and if so, what's the technique? Thanks much
- Ball joints and tie rod ends are like the joint in your hip. The BALL of your hip rotates around in a lubricated depression. Many BALL JoiNTS and TIE ROD ends have lubricant fittings for grease to get pumped into. It prevents damage to the metal ball and cup. OTher cars are totally sealed. Either way is just fine. I prefer sealed opnes on most cars, but only if they have an UNLIMITED warranty. NO MUSS,NO FUSS!
- Q:What is the reason the inner ring of some roller bearings are tapered, while others are flat-bored. What are some of the typical applications for roller bearings that are tapered on the inner ring?
- The tapered ones are made to take a side force. .
