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:make more noise when they are in rictas?
- its the bearings because i have rictas and it makes a lot of noise and my friends always say that their really lloud
- Q:On a scale of 1-10 how good are abec 3 skateboard bearings?
- They can be between a 9 and 10 or they can be a 1. The ABEC number is basically useless for skate bearings. It is related to vibration at very high speeds (over 200 mph on a board). The tight tolerances on the high ABEC ratings can actually slow you down which is why the high end company (Bones, Zero Drag, Twin Cam) all make bearings without any ABEC rating as their top bearings. However, there is a spec called precision that is really sloppy and was in common use before people started getting ABEC 1 bearings for the consistency. The biggest thing that 99% of the people will see as a difference in speed of the bearing is the lubricant that they maker put in the bearings. Grease will be slow at first until it is pushed mostly to the side but it lasts the longest before you need to relubricate or replace the bearings. Oil is the fastest but doesn't last long. Gels are in between in speed and life.
- Q:Its a yamaha r6 2002 model and im trying to remove the back wheel bearings.I have pulled the oil seal off and the circlip but cant get any further.The bearings arnt moving when i tried to tap them out.Do i need to take the wheel to a dealer to press the bearings out with a special tool made for the job or is there a way to remove them on my own and how do you put the new ones back in? Any advise would be greatly appreciated as i need my bike for work and at the moment its in bits and cant put it back together until this is sorted.
- R6 Bearing
- Q:what is the proper tightness when installing wheel bearings ona vehicle?
- depends on what kind of vehicle alot are in the 260 ft lb range others which are tapered bearings tighten and then back off alittle to put in cotter pin
- Q:I am interested in cleaning my roller blade bearings so that are free of sand.I saw a recommended video to wash the open ball bearings in acetone but I need some help understanding how to get my bearings to run their best.I found some nail polish remover and I am planning to wash the bearings in a small bath unless anyone knows if a more pure formula of acetone might be safer.I'm still doing some research and I found some chemists on the internet mentioned balancing the alcohol to water ratio 1:1 with acetone sort of like with mouth washthey also mentioned that methyl acetate and how it might help to filter it out. I'm wondering I'm now interested in seeing how acetone might react with sand (SiO2) but I'm actually thinking it might just dissolve it.What does everyone else think?Is there a better way to clean bearings? (excluding lube)
- Absolutely none of the liquids you mention will react with SiO2 or dissolve it. There is nothing that will dissolve SiO2 that won't also dissolve your bearings. The point of the various bits of advice is that the acetone (or whatever organic solvent) will dissolve the lubricant in the bearings which is holding the sand grains there. Whether you use nail polish remover, or acetone (diluted or not) or gasoline or kerosene or maybe even alcohol doesn't much matter. (Although in all cases you need to observe the safety precautions about inhalation and fire hazards, and keep the solvent off of the upper parts of your roller blades.) Your goal is to remove all the oil (or whatever lubricates your bearings) then let the bearings dry completely. Then you should be able to remove any left over sand by brushing it out of the bearings with something like a soft brush or blowing it out with compressed air. After all the sand is removed, you need to re-lubricate your bearings. (I've been assuming all along that your bearings are metal. If they are not, you need to be careful about your choice of solvents, lest you dissolve your bearing too.) I doubt there is anything else you can do to remove sand from your bearings. In the long run it's probably easier to find a place to roller blade where there isn't so much sand.
- Q:i dont understand much about cars so can u explain it so i can understand
- the bearings are the attachment points for spinning parts. they allow virtually frictionless rotation with oil lubrication. think of a hand held pinwheel. the propellor is turning on a shaft. this is an example of a bearing on a shaft.
- Q:buying my first skateboard.
- the bearings are what make the wheels move on the trucks and it holds the wheels to the trucks .. its the thing inside the wheels and it can be any color like mine are red
- Q:Any suggestions? Been lookin around.. found arsenal abec 9s reeeeallly cheep but i cant find them anywhere to see how bad they are if i can get 16 for $10. Secondly my skates are about 4 years old should i get new spacers as well?
- I don't know that brand, but at that price I guess you can't go wrong. I personally use Swiss abec-5's, good performance, speed and durability. And yes do get new spacers while you're at it.
- Q:Should i get better bearings and is it ok if your foot is a little turned when you kick the one on the board im regular and i weigh 236
- Try Redz. Your bearings are probably old, so they don't function as well. Another possibility is that you left them out in the weather and they have rusted. Try buying some new ones. Redz are fairly priced ($20) and great durability.
- Q:I got a set of bones reds skateboard bearings about 5 months ago and i heard that theyre really fast. but they have been really slow ever since ive got them. today i squirted wd-40 inside the wheel over the bearings and span them for ages and they span for ages really fast. i heard wd-40 is bad for skateboard beasrings though? i only go to indoor skateparks with it so they dont get that dirty
- Common mistake. WD-40 is a penetrating fluid; it dissolves oil and grease. You need to re-grease the bearings.
