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:thanks for your help
- If okorder /... If you're talking about dismantling the actual bearing... Take off the shield with a needle or something, hit bearing multiple times until it breaks. Gather pieces.
- Q:I have a Dynacraft Next Turbo bike,I have called on the cycle companies and said I would need to call the Next company.So I was wondering,what are the crank bearing sizes for the bike? Thanks!
- Try okorder ( don't forget the dash in between the words )
- Q:Im just wondering how important it is to clean and regrease a cars wheel bearing. Working as a bicycle mechanic, this is something I do on a daily basis to every other bike we work on. And so Ive always wondered why I dont hear about wheel bearing going out on cars, or why I dont hear about having them serviced...Im assuming they are sealed bearings, but still it seems like they should need serviced every so often. I drive an early 90s ford truck, nothing fancy. Is this something I should consider doing, or should I not worry about it unless they start making noise?Thanks!
- It depends on if your truck is 2 wheel or 4 wheel drive, on a 4 wheel drive truck the front bearings are not serviceable and are replaced as a sealed unit when they either have axial movement in them or when they are making noise (usually starts to humm or groan and changes with speed and turning) on a 2 wheel drive truck the front bearings are serviceable and are usually inspected and either replaced or re greased when you have your brakes replaced, it is usually not necessary to have them worked on in between brake jobs. The rear bearings on either a 2x4 or 4x4 truck are lubricated by the rear axle fluid and are usually only replaced if making noise, there is no way to grease them besides changing your rear axle fluid
- Q:Front wheel bearings
- You normally just check the bearings when you do the brakes. Then you clean and repack them. If you get front wheel looseness or noise, then you jack it up and check for bearing play, or hear grinding.
- Q:I need new bearings, a freewheel remover, and a cone wrench, I'm not sure what size on the cone wrench I guess 15 mm
- You may need a lot more than the bearings. If the wheel is really bad the cones may be shot with a possibility that the bearing cups are finished as well. If that is the case, your wheel is done, finished, toast. The only way to find out is to take everything apart. Don't buy anything until you have taken the axle out, the freewheel off and have inspected everything
- Q:Took my car to the mechanic yesterdcay because it was occasionally making grinding noise when turning right they said its the bearings and i don't have the money to get it fixed til next wendesday. I have to drive to school on tuesday which is an hour from my house...will it be dangerous to take this trip before getting it fixed? The car is a 2003 dodge neon
- my opinion, yes it would be dangerous to drive it, for one it could lockup and cause an accident causing bodily harm to you and others. Also if the bearings seige it will cause addional damage to your vehical and result in a more expensive repair.
- 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 heard that gas makes skateboard bearings go fast and go a long time. Can you do it with sealed bike bearings? If so, how long should it soak?
- Fred, You should never soak any type of bearing sealed or otherwise in gasoline. Bearings and their races are very hard. Without some kind of lubrication they would be ruined in minutes. For you're skateboard the hot ticket for ultimate speed would be an aerosol spray can with suspended Teflon. You must repeat this after a day's use. It's still available although a bit hard to find. I recently found some on line. Just type in: Teflon spray. The next best item for load carrying bearings would be lithium spray grease. It may not be as fast but ambient temperature doesn't thicken this type of lube. It also would give you more protection over a longer period of weeks.
- Q:I use the NSK rcb061014 one-way needle roller bearings, I ask you, what is its working principle, how to achieve locking?
- One way bearing is a type of bearing that can only be turned in one direction and locked in another direction.The metal shell of the one-way bearing, contains a lot of rollers (or needle ball), and the rolling block (acupoints) shape so that it can only roll in one direction, (because the installation direction of the rolling direction opposite spring, so spring is compressed). In another direction when the rolling direction and spring mounting same direction, not to cause the compression spring, up roller, roller to produce a lot of resistance in between the inner shell and outer shell (the so-called "one-way"), stop rolling bearing.
- Q:On my longboard the bearings are sliding out of the wheels as i ride and causing the nuts to tighten and me to fall off. Why is this happening and how can i fix it?
- please post in the proper category this is Cycling, as in Bicycling not Skateboarding
