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.

Needle roller bearings are mainly used in car engines, transmissions, compressors, cranes, etc.

- Q:I want pro bearings that would be kinda cheap and i found these
- Kyle Take off the wheel Look at the bearing, there should be a 4 digit number like 6008 That's your bearing size If there's no number you have to measure the outside and inside diameter with a vernier caliper and plug the size into google to get which bearings you need. But probably standard skateboard bearings most likely.
- Q:are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?
- The ABEC scale isn't very accurate for measuring how fast a board can go, hopefully we will one day get a scale that is accurate. You're Bone Swiss bearings probably do go faster, when you're riding your board, challenge him to a race, either you'll win or you got ripped off.
- Q:I got my car alligned and suddelt every time I turn it makes an awful groaning noise. I believe it's the bearings but I JUST had them done a year ago and hardly drive... Could the allignment have caused this? A year seems like such a short time for bearings to last.
- 30,000 miles? could have been dealt with under guarantee? tires somewhat shouldn't reason untimely bearing failure, until they are way out of stability inflicting shaking. The bearings won't have been worn sufficient to be observed while the hot tires have been positioned on. possibly your new tires run quieter so which you pay attention extra noises that have been hushed via the noisy affordable tires you had until now?
- Q:I currently have reds skateboard bearings and they are pretty good but i'm getting a new custom complete and i heard that bones bearings are pretty good to, if you guys can help me out, even if there are better brands post me an answer. Thanks guys.
- Same Brand
- Q:i have bearing that i want to use for my skates and i don't know if they will fit
- Yup, you sure can.
- Q:I was driving my 98 civic ex automatic around a corner, hit an icy patch and slid up on to the curb. (impact was on the passenger front tire) After the curb incident my left front end bounced up and down and when I would speed up the wheel started to shake back and forth.I drove home slowly and parked it and I am unsure wheat to do. The tire is not flat and it looks like two of the 4-lugs are sticking out further than the other two(?)...Does this sound like a case of broken ball bearings??If so, are they expensive/hard to fix??And, how long will this take at a shop??
- i think you meant a rod or something, ask a mechanic for the price, like 2 days to a week
- Q:I refer to the overhung impeller pump. They normally have two bearings supporting the shaft, (and an oil box between the bearings). Why is that? why not only one bearing? what would happen if they are manufactured with one bearing only?
- This is a rough guess by an electrician. There is a lot of radial pressure on the shaft of a rotary pump. Were pumps to have only one bearing, the bearing would have a lot more pressure on one side of the race than on the other. This would cause the bearing to fail. With two bearings, set some inches apart, the radial pressure on the races would be small.
- Q:are swingarm bearing and linkage bearings the same or do u have to buy 2 different kits
- Linkage okorder /
- Q:what is the best bearings company for my skateboard?
- it's pretty personal. some people just get the cheapest bearings they can find, and just replaces them once, twice, maybe more, a year. but i tend to agree with the user above me. if you buy bones swiss (i think they're about 40$) they're not only very fast, but they should last you at least a year. and if you take a step up from the bones swiss, then they are lubricated, and lubricated bearings (although initially faster) tend to pick up junk off the road and will slow down over time more than bones swiss will.
- Q:i noticed they had some dirt in them after rideing around a bit and it happens to be from just 2 bearings from 1 wheel, ive completely disasmbled the bearings and tried to put them back to getter but the ball bearings just keep locking up on me !!! its been frustrating me like crazy man, and i know its not from not having lube they always have lube in, its just the reassembly that wont go well.
- you are the main stressful brat I even have ever heard. U deserve your punishment infact i'm hoping she cuts your internet off and locks u in there for 3 days. Skipping college, staying out previous due? If i replaced into your mum i does not permit u bypass away the domicile for each week nor having the flexibility to apply any cellular units. in line with hazard you could have the flexibility to experience like a technique of ravenous babies in a 0.33 international united states of america and journey that they don't even GET to bypass to college yet you have chose to pass college. Disrespectful little brat
