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: can i use rubbing acholhol?
- sure but i used to use black magic tire wet on them, to keep em moving fast! Also a rag with soem wd-40 will keep me in good shape and acutlly keep em cleaner longer, though grim may stick to it they be nice and slick for while, dont dont use anything water based.
- Q: or witch hazel? im just looking through my cabinet and seeing what i have....
- i cleaned my bearings yesterday and i used an air compressor to knock the dirt off then i spin my wheels as hard as a can and apply WD-40 while they spin, then i spin the wheel for bout 10-15 seconds so it sets in wipe of access then ride! ( do this for each bearing and or side)
- Q: The serpentine belt in my car came off somehow and I found it in the driveway (this was a few days after it had been replaced) and my dad told me to drive my car to the automotive place without it and if it overheated just to pull over, let it cool, and then keep going. it did overheat and I pulled over, but called AAA and had them tow me, now the guy fixing my car told me my alternator bearings have failed, and that it wasn't like that when he did the belt before. Was this from the drive there? or from something else?

- Q: I have recently purchased a longboard with abec 5 bearings. I have a regular board, with abec 7 bearings. I plan to use the longboard more, and i want to no if it will work to use the regular boards bearings for the longboard. Anybody know?
- It should not matter. And correction... The less balls in a bearing the faster it would roll because each ball doesnt need to turn as much to make it all turn. Anyway... Abec doesnt matter much to do with skateboarding it just means how small the tiny allowances in each bearing is... So it doesnt affect skateboarding much. Its mostly for machinery... BUT yes the bearings should work fine for the longboard.
- Q: How do you CHANGE WHEEL BEARINGS on a Suzuki Quad? I can see the outside one (there are two per side) but I am not sure how to remove and reinstall them. Are there special tools needed? What are the steps?THANKS!
- use a long skinny punch to drive the old bearings out from the opposite side... then use a socket of the proper diameter and a hammer to carefully drive the new bearings and seals(when applicable)into place....I recommend buying the manual for your particular machine, they can save you a lot of money and headaches...
- Q: i have bones reds bearings and i dont know if there abec 5 or abec 7 tell me what you think?
- bones makes many types of bearings. Some are ABEC rated and the better ones are not. The ABEC rating is for vibration in high speed machines that run at speeds similar to skating over 200 mph. They are not the best design for skating but companies make a lot of them for other reasons and it is cheaper to get them than a design that is custom made. Bones, Twin Cam, Zero Drag, and some other companies have custom designs for their better bearings.
- Q: Right now I'm riding on Element Skate Bearings and I tear them up real easily. I mostly ride street, so of course smaller wheels. What do you guys recommend?
- Get okorder / (click the link and scroll down to the bottom where it says Reviews and click one) Good luck man, hope you find what your looking for.
- Q: just for crusing
- If you got money for $80 dollar bearings than Bones Red Ceramics are some of the most fast best quality bearings. The fact you gonna use just cruise makes it better,cause the material ceramic is not made to resist impact well. So if you simply gonna cruise than they should last a long time. But if thats to expensive than Bones offer other bearings.. They are all quality and perform well. Some regular Bones Reds are good and fast they go for like $ 20bucks. Any bearings made by Bones are good. And Black panthers are another good quality bearing brand.. To me those 2 brands are some of the fastest ,best quality bearings .
- Q: Im not sure how to open it up.
- I just lubed up my skateboard bearings today. Sometimes you cant remove the shield (the yellow-gold part in the picture). If the shield is removable you can take a razor blade and stick it in the tiny gap between the shield and the bearing wall and lift up the shield to expose the ball bearings. you should do it carefully so you can put the shield back when you're done. If you're doing this to lube up the bearings, drop in a couple drops of lube and pinch the bearing and spin it so the lube coats the inside. then brush the ball bearing with a q-tip to remove excess lube.
- Q: I have a Myrtle Longboard with Sector 9 wheels...right now my wheels spin for about 30 sec...how long would it spin approximately with bones reds?
- Free spin doesn't mean anything. You don't need new bearings unless yours are broken or rusted/seized. They won't make any difference. My Bones Reds spin for about 5 seconds.
