Application for needle roller bearing :

- Needle roller bearings are largely suitable for automotive transmissions

- Air-conditioner compressors

- Bulldozer blades

- Overhead traveling cranes

- Gearboxes

- Machine tool spindles

- Copying machines and many more

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: 1973 buick centurion. posi rear.: As stated above, check them while replacing the seals. A lot of the times, you can just repack them as long as they're in good condition.

Q: Needle roller bearing is also called cam bearing?: Needle roller bearings are needle roller bearings

Q: Needle roller bearings are how to process the needle, so smooth finish?: The process of needle: blank forming, deburring, heat treatment, coarse and fine grinding, end rolling surface, super finishing rolling surface polishing or sawdust.For flat head or taper head needle roller, such as blank forming, it is difficult to guarantee the length and size tolerance, and the grinding double end process can be increased. If the convex generatrix rolling surface is needed, it can be carried out directly in the process of super finishing, rolling or channeling.Needle roller bearing (needlebearing) is a roller bearing with cylindrical roller, relative to its diameter, the roller is thin and long. This roller is called needle roller. Although it has a small section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, the minimum diameter of the diameter and load capacity and other types of bearings, bearing the same, especially for the radial installation size limited. According to the use of different occasions, can choose the inner ring of the bearing or needle roller and cage assembly, the shaft neck surface and the surface of shell holes matched with a bearing directly as the bearing inner and outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness the machining precision and the surface quality of bearing ring raceway and similar. This kind of bearing can only bear radial load. The needle roller bearing for stamping outer ring is needle roller bearing with thin stamping forming outer ring.

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: Ive put some 18 wheels on my car (which shouldnt be a problem because I know people with bigger ones on a golf) as soon as they went on, the car makes a howling noise from the front, a bit like a wheel bearings gone, or they are catching on something? There are no scuff marks on the wheels or tyres and I got a mechanic to check the bearings and they are fine, It sounds worse when the car is slowing down, ive also had the wheels checked and balanced, there is nothing wrong with the alloys but one of the tyres was slightly mis-shapen but ive been told thats not the problem, any ideas please? Dont feel safe driving it until I know whats causing itThanks: Hi, the front wheel bearings on the golf's are not a tapered type and are very hard to check for freeplay / wear when car is jacked up...I have worked for VW for 30 years and changed many of the front pressed in type bearings....the only sure way of testing which side bearing is noisy is to spin the wheel up to a high speed with car jacked up and feel the bottom of the shock behind the wheel hub were the hub is bolted to it, if the bearing is worn you will feel a grinding sensation through the hub. This can be very dangerous if you are not careful....we used a mobile wheel balancing machine to spin each wheel up while, it was jacked up on one side... I would not try this if I was you with no training...Get a 2nd opinion from your local VW specialist or come and see me if you are in NW UK...

Q: im trying to buy speed skates not roller blades any suggestions i don't want any skates over $150: abec is not a real rating for skate bearings its a rating for industrial bearings and has nothing to do with speed in the first place. abec 9's could be worse than abec 3's you just never really know. Swiss on the other hand is a real rating and is way better than any abec bearing, you can never go wrong with a swiss rated bearing. Swiss bearings are smoother and longer lasting even if it's not bones brand it's still a good bearing. People will tell you anything in order to sell you something don't let skate places fool you into buying these faster abec rated bearings. No such thing.

Q: This is a technical question depending small losses for example in clean room applications (every particle matters...): I assume you have tried shielded bearings, where the grease is contained inside covers that prevent its loss? Or possibly you do not have the funds to replace the bearings? Etc. I do not know the size of your pump/motor or whatever the bearing is on. I will tell you I have seen in an industrial setting on what I would call a small pump, they actually put a bag around the bearing housing to catch grease. Of course, the shaft ended at the housing so the bag did not have to come in contact with the rotating assembly. You could probably get more useful answers if you re-ask your question describing the size and physical configuration of the bearings and their housing.

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 is the bearing capacity of needle bearing and copper sleeve?: The bearing capacity of plain bearings with copper sleeve is large. However, the speed of the shaft has a certain requirement, the speed is too low, too high, can not establish oil film, will soon wear.
