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: okay so i just wanted to know where i could get the bearing cage retainer( holds the bb's ) i came across a site but i want to find something thats cheaper in price but still last a good or long amount of time, and also they have the bb's but they dont say how much come with the purchase and dont know which brand is good.so if you know anything about which is a good brand please help me out.i want ones that spin good and good cage retainers.please give me the sites if you know any or where i can get them.oh and for skateboards just in case anyone missed that the first time.and dont write me saying just purchase them at a skate shop.i already have bearings in my tool box that need to be cleaned i just want to get some cage retainers and the right sized bb's.thanks.

- Q: what is the difference between alloy bearings and plastic bearings?
- Alloy bearings are med out of metal alloys. Plastic bearings are made out of plastic. The metal ones are more durable and last longer, but are heavier than the plastic ones.
- Q: Are bearings measured in diameter or circumference?
- Neither one. Bearings are measured in degrees. Or, do you mean bearings as in ball bearings? Those are measured in diameter.
- Q: plz answer if you have a skateboard and understand the difference
- The difference is that you are asking which is better a Ford or a truck. 608 is the standard industrial size spec for bearings used in skates and boards. Z indicates a shield. All bearings that will fit your board are 608. ABEC 3 is an industrial standard for tolerances in the bearing. Higher numbers indicate smaller tolerances and less vibration at high speeds (industrial speeds that are equivalent to a couple hundred miles per hour on your board. ABEC numbers are basically meaningless for skates and boards. There is more difference in quality between makers than in ABEC 1 and ABEC 7. The lubricant used in the bearing will have more effect on speed than different ABEC ratings.
- Q: I need to order bearings for the neck of the frame on my bike. I do not know what that piece is called or what i would look for as far as bearings go. Thank you
- Steering stem bearings, and generally speaking stock s.s.bearings are loose and sit in metal bearing races. They should be cleaned and lubed particularly in a dirt bike, every season, or more often as dirt, grime and extreme wear and tear cause problems.
- Q: I've cleaned my 5000-C but the spool doesn't let line on unless you pull even with everything turned to the lowest. Im trying to figure out if the inside has bearing because the bar in the spool doesn't come out at all. Is this normal or is it suppose to come out once you remove the white gear? Need help asap... I've got two other Ambassadeurs and would love to use the 5000-C as another go to reel. Thanks!!!
- the only bearings on the 5000C are the ones at the ends of the spool shaft. one external, underneath the tension adjustment cap and the other inside the opposite sideplate, held in place by a small metal clip. *the only BALL bearings. other turning contact points have bushings which to a nit picker, are, in fact, bearings.
- Q: ABEC 7 Chrome Steall or ABEC 7 Carbon plz awnser 1st awnser get best answer
- hard to tell, I bet they are the same if you broke them in. It can take months of constant skating to break in a set of abec bearings. You never know what you're going to get with abec rated bearings because that rating doesn't mean anything for skate bearings only swiss does. Use some speed cream and break them in and you'll have some fast bearings.
- Q: i had abec 5s bearings on my longboard, and a friend told me that bones swiss black bearings would be faster. i dont do tricks on my board i just cruise around. so i bought them for about 50 bucks. i put them on my sector 9 wheels and i spun them. with the abec 5s my 2 back wheels spun for about 35 seconds each and the 2 front ones spun for about 20. now they all spin for about 15 seconds each with the swiss bearings! and these are supposed bones swiss! are they messed up? do i have to grease them a bit first? or am i using the wrong wheels? until then im using my Abec 5s
- Check to see if the bearings are seated correctly in the wheels. If that's not it, check to see if the nuts that hold the wheels on are too tight. If you loosen them a little, the wheels should spin better. You should also have 1 washer on each side of the wheel. This prevents the bearing from touching the truck and slowing it down. How long have you had the bearings? It usually takes a few week before they start to spin their best, once some of the oil they are packaged with dries out a little.
- Q: can i install crankshaft bearings without taking the crank out if so? how?
- No,the bearings need to come out so you can first clean the crank journal and second measure the dia.of the journal on the crank and the block to see if you have any wear and what size bearing to go back together with,either standard or an oversize bearing.
- Q: How many times have you had your front bearings go bad on your Alero, what approximate milage? I'm at 87k and am ready for my third set!
- what conditons are your vechicle put through every day,pot holes,bumpy roads all factor in to the life of your bearings,the next question is what brand of bearing are you using,Factory bearings tend to last longer,There has been alot of time and money spent to engineer these vechicles from GM.Hope i helped.
