Needle Roller Bearing High Precision
Description
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.
Feaures
Full compliment bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each U joint) and often more if it is particularly long, or operates on steep slopes.

- Q: Whats better and why?Lucky Abec 7 bearings or Bone Reds?
- Bones Reds bearings are personally my favorite bearing cause they are pretty cheap and will last you a very long time plus they roll smooth and fast ive rode some i got for maybe almost a year and they still ride great
- Q: 4-ball bearings that i modded myselfhere's the link:
- well i dont know if its a good idea but they look fast :)
- Q: I have a 1990 240sx that has an Sr20det motor. I was driving home one day and about 15 minutes from home my engine started sounding like marbles. When I got home after only 15 minutes of it sounding like that I turned it off and removed the oil pan and there were definitely pieces of rod bearing in it. My question is, after driving for only 15 minutes home, could it have more damage than just the bearings?
- I agree with mike. A lot of the time a motor is just like a row of dominos. not the pizza lol once one thing goes the rest will always seem to follow.
- Q: Plz but the store/website down too! Thx
- Good bearings are Bone Reds and fast as Hell. Fast as Hell are about $10. They last me about a year . Those are the only bearing i use now.
- Q: I lubed my bearings, loosened trucks, loosened my wheels, now I hear a rattling noise, wheres it coming from?Its a longboard. The wheels are made of like a rubber substance, so I dont think the problem is inside the wheels. The noise sounds metallic, so Im guessing the noise is coming from the outside wheel bolt, or the top cup washer. Can anyone experienced or knows the answer help me out? Im an amateur Please help me out. The sound gets annoying to me and my friends when i cruise.
- Do you have bearing spacers??? They go inside the wheel between the bearings. They allow the bearings to be tightened all the way without messing up the bearing.
- Q: How to clean your skateboard bearings ????
- Well, What You Wanna Do is Take Them Off The Wheel, And Get A Piece Of Wet Clothing, And Make Sure its not To Wet, And Not To Dry. And Gently Wipe The Bearing, Dont Scrub it Well Mess Your Bearings up. And After That You wanna Blow On them For a Little Bit, And Let them dry For A Little. And If Can Ask What Type Of Bearings Do you own?
- Q: two of my bearings are slightly dented. What can I do? I just bought new bearings and I had to change them because I bought new wheels. :?
- If your bearings are dented, there is nothing that can be done about it. Either suffer with the wiggling until the bearings fail, or replace them.
- 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: what kind of bearings do i need for a1976 honda cb750?
- Phillip missed it on several points. The crankshaft main bearings and con rod big ends are replaceable plain bearings, small end rod are non-replacable plain with full floating wrist pin, camshaft plain, tranny shafts are caged ball bearings, steering head are loose balls (really cheap crap), swing arm pivot are plastic bushings (really, really cheap crap) and the wheel bearings are caged balls. You should be able to replace the steering head and swing arm with tapered roller bearings, which will really improve handling.
- Q: I have a Merida sub-20 bike. can i use sealed units? if so, what size should i use?I want to change to sealed bearings to make it easier to replace/fix. many thanks
- You will have to switch out the headset to go from caged to sealed bearings. Most modern bicycles come with a 1.125, also known as 1 1/8 inch headset. It would be a very odd late model bike that would come with a 1 headset. If you want to replace it yourself check out the links below for all sorts of useful information. Remember that most of the race cups into which the bearings fit are aluminum and are relatively soft so use wood or a special tool to install correctly. Headsets are definitely one area where a bigger hammer does not work. Setting the star nut requires a lot of patience or a special tool, so think about having a shop swap the headset. It's a common repair and with the right tools reasonably quick. Best of luck!
