Needle roller bearing :
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: Okay, I have a 99 olds intrigue 3.8 with 100k miles. Recently, I started noticing a clicking noise when turning right. I replaced both CV axles, and it did not go away. This noise ONLY happens when the car is on the ground. it happens in neutral or drive, braking or no braking, and only happens when I trun right. Now, recently I noticed the car makes a horrible grinding noise when the wheel is LOCKED to the left under acceleration. (like making a U-turn). Could both noises be caused by a bad wheel bearing? or bearings?
- replace both wheel bearings, you figure, the car is resting on them, if they're grinding as you say they are you should feel a slight vibration in your gas pedal. for the clicking take it to a few shops see if anyone knows. after that i really don't know what to tell you.
- Q: Are they connected with the main bearings? Are the trust bearings only on the outer portions of the crankshaft?
- The thrust BEARING (there is only one) is part of the transmission. It's separate from the main bearings of the engine.
- Q: Air bearings have been used in large centrifuges and gyroscopes.
- It could be applicable to electric cars and also maybe more applicable in the AirCars that TATA is producing in India (and with plans here in the US). Where the air cars have a ready supply of compressed air they use for propulsion the electrics would need an electric motor to drive a compressor. The think is that since these bearings are frictionless the amount of energy used to feed the bearing only has to overcome the amount of energy normally consumed in friction. Not sure what bearings though... lots of bearings in any automobile, electric or otherwise. The thing is with air bearings the load has to be fairly constant. Could never use them in a recipocating mass like crankshaft, connecting rod bearings in an internal combustion engine. Would work in a turbo-charger though.
- Q: I have a 98 Jetta GL and my left rear shock absorber has begun leaking fluid in the past month or so. I have also had issues with the bearings wearing out, so I had them replaced less than 2000 miles ago. But now these newly installed ones are giving me the telltale signs of going-to-crush-soon. Could a failing shock absorber cause uneven wear/premature failure of my rear wheel bearings? I know that the bearings were installed packed correctly.Also, on the hub assembly the nut that goes on just before putting in the cotter pin tends to loosen after about 50 miles of driving. I continue to tighten it, then back it off slightly but the problem still occurs. This occurs on BOTH rear wheels. I am at a loss for what can cause this. Help!Thanks!
- HI no shocks don't cause ware on bearings... did you get the ring back on the goes over the nut that you install the cotter pin Thu? That holds he nut from turning and backing out.. good luck tim
- Q: My Escape started making a noise at about 35,000 miles. At the time the dealership said it was the tires. I replaced the tires. The noise did not change at all and now has progressively worsened and now they are telling me the right, left AND center wheel bearings need to be replaced (at my expense since now the car has 42,000 miles). They did say the bearings are still sealed and there is no water damage and no other obvious damage. I think they must be defective and Ford should replace them as from what I understand it would be very unlikely for all 3 to just go out at 35,000 miles. I'd like to know if Ford has addressed this problem for anyone else and also if anyone has any ideas on how to make Ford provide the parts and repairs at no cost to me.

- Q: what year did they come out with them? i know swiss came out in 83
- Bones Swiss bearings came out in 88. There were other Swiss bearings on the market, though. Reds are much newer, coming to market in the early 2000s
- Q: and what are they used for?
- there iside the wheel thats what lets it roll
- Q: I have a 1996 saturn sc1 and the rod bearings are gone in the motor. I'm i better off taking the chance and replacing them or buying another motor, because i was told that if the rod bearing are gone, 9 chances out of 10 the cylinder walls are gone as well. Is this a true fact?
- i don't know about that, but my sister had the same car for a while and it burned oil like an SOB. if you fix it, you should probably sell it soon. those cars just don't hold up that well in my opinion. maybe just put a used engine in it and sell it. it would be cheaper. but those engines do have a problem with oil usage, if you rebuild it go ahead and have the walls honed and new rings put in.
- Q: what does ABEC 7 Speedster bearings mean for roller blades?
- It basically means nothing. The use of ABEC ratings was an accident in inline skating. It is about bearings used in machinery that runs at extremely high speeds. Nothing about rolling better under the weight load or speeds for inline skating. Some of the bearings used for the early inline skates were so poor that any ABEC rating guaranteed that the bearings were reasonable. Then the manufacturer's got their advertising people into the act by bragging about a number that isn't important or expensive.
- Q: how do u clean skateboard bearings?
- you take s socket wrench and loosen the nut and take it off and take off the washer , than the wheel than the other washer . Don't lose ur washers !!! Do this to each wheel . Take about 8 Qtips or more or less depending on how dirty ur bearings are , take the Q tip and rub the dirt off of the bearing . Each side and in the insides .
