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:plz answer if you have a skateboard and understand the difference
- 608z Bearing
- Q:I have noticed that my ride is very noisy. I thought about replacing them but they come as the whole assembly. Please help!
- they are not serviceable but i made a device using a zerk fitting and a hypodermic needle along with my grease gun that allows you to grease the bearing. Snap on tool has a similar device used to grease the heads of air ratchets
- 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:A ship is sailing through the water i the English Channel with a velocity of 2 knots along a bearing of 157 degrees. The current has a velocity along a bearing of 213 degrees. The actual velocity of the ship is the vector sum of the ship's velocity and the water's velocity. Find the actual velocity.Ok so i understand how to do the actual problem, I just have no idea how to convert the bearing degrees into standard form so i can do the problem. I looked at my teacher's review and she gave the standard form for the bearing of 157 degrees as 293 degrees, and the 213 degree bearing as 237 degrees. Well I looked at them and found that the both add up to 450 degrees which i thought might be the solution, but I looked at another problem that had a bearing of 60 degrees and standard position of 30 degrees. Thanks for any help in advance.
- true bearing is a navigational angle. it is oriented such that 000 is at due north, and it increases clockwise. a mathematical angle is oriented so that 0 is at due east and it increase counter-clockwise. as a result, the relationship between the true bearing and a mathematical angle is A1 = 90 degrees - A2 where if A1 is the navigational angle, then A2 must be the mathematical angle, or if A1 is the mathematical angle, then A2 must be the navigational angle. That's why bearing 157 degrees = 90 - 157 = -67 degrees = -67+360 = 293 degrees and bearing 213 degrees = 90 - 213 = -117 deg = -117+360 = 237 degrees === so as long as you convert bearings into mathematical angles, then you can resolve vectors into (x,y) coordinates using the standard transformation x = r cos(t) y = r sin(t) where r is the magnitude of the vector and t is the mathematical angle. otherwise,you have to use x = r cos(90-t) = r sin(t) y = r sin(90-t) = r cos(t) where t is the bearing
- Q:My high flange track phil wood hubs need the bearings replaced and i was going to go to a bearing manufacture i know of as opposed to having a bike shop order it. Are they standard 6000 sealed bearings or something different?
- The bearings will be standard items. Simply take the old bearings with you when you go to buy new ones, the people at the parts counter will be able to measure them and get you the replacement bearings that will fit
- Q:well i thought my skateboard was lame but i figured out yesterday i had to loosen something,but the thing is, i don't know what, the bearing or trucks and what's the use for loosening or tighting each onep.s. what are some good skateboards for cheap and where can i buy themthanks in advance
- deffinatly okorder
- Q:Okay so I wanna clean out my bearings, but I dont have any rubbing alcohol, but I do have hydrogen peroxide...I was wondering if it works and how to use it. Plz tell me asap!!! also, does sewing machine lube work to lubricate the bearings?
- first of all NEVER use things like hyd. peroxide or sewing machine lube or WD-40. it clots up, collects more dirt and actually can cause more friction between the ball bearings and the shell. and absoloutly never use water, unless you want rusted shackles. only use actual skateboard lubricants, top kind out there right now is Speadcream by Bones.
- Q:i heard about bones but are there any others?
- doesn't really matter but just ger bones reds, or flip HKD. the best is bones swiss ceramics fer like 100 bucks
- Q:I have a 100 dollar budget on either trucks bearings or wheels. I have been riding my long board for a while but I dont really know to much on how most of the parts work. I want my longboard to go faster and stay fast for a while without slowing down. Should I buy new bearings or trucks. I have a sector 9 bob marley pintail longboard with bone reds trucks. If I buy knew bearings or trucks do I have to buy new wheels as well. But If I had to pick either buying new bearings or new trucks which one would be best for my longboard. thanks
- If you have $100 you can seriously buy both. But if you are looking for longer roll time, bearings are what you need. NEVER SPEND A LOT OF BEARINGS!!! Bearings should never cost more than $15. If you get a good set of bearings and keep them cleaned and lubed when needed, there will be no difference between $100 bearings and $10 bearings. I recommend MileHighSkate or Magic bearings if you can get them. They are high quality and $9. If not, Bone Reds are easy to find, but arent as nice and cost $15. I also HIGHLY recommend you get bearing spacers. They are $5 and go inside your bearings and allow you to tighten your wheels all the way, giving you a smoother ride. You should also have speed rings too (those 8 rings that come with your current trucks). Trucks will not help you go faster.
- Q:i have an 2001 ford ranger and it sounds like a bunch of rocks or marbles sound coming from my rear wheels. does that mean i need new bearings?
- If the noise increases with speed yes, check your rear differential to see if its low on fluid and get the bearings changed out. Bearing seals also may be leaking diff oil over your rear brakes.
