Q:What are skateboard bearings?
honestly i dont remember all to well, i had a boyfriend in hs that skated and he would take me to skate with him and i havent gotten on a board for years, lol. or go to ur local skate shop. :)
Q:How can i get the wheel bearings out of the back wheel of my yamaha r6 2002 model?
Not sure about Yamaha but some BMW wheels must have wheels heated up to change berings.
Q:are bearings Dust Cover unique for specific wheel/hubs?
? dust covers don;t affect the bearings you must have something misunderstood if the bearings come out you have problems but that would be a matter of wrong bearings or wrong cones, not bad dust cover wle
Q:Working principle of one-way needle roller bearings
The main structure of the unidirectional bearing EG unidirectional roller bearing EG-- | stamping outer ring needle roller clutch (one-way bearing) can be used as a converter, a non-return device, overrunning clutch. HF (needle roller clutch): composed of stamping outer ring and plastic cage. The cage can be provided with plastic spring or stainless steel leaf, guide roller, roller, roller and needle on outer ring as locking device. HFL (clutch and bearing assembly): support bearings are mounted on both sides of the needle clutch and bear radial loads. The needle bearings and plastic cage assemblies are used as supporting bearings
Q:How do i convert conventional bearings to true bearings? maths?
Bearings are usually measured clockwise from true north, so S is 180°, and W is clockwise from there, so we would add 47° to 180° to get S47°W has a true bearing of 227°.
Q:f-250 changing front wheel bearings?
Well, what's the problem? Do you need to know how to do it? How much it cost? What are wheel bearings? You have tapered bearings. When they go bad you change the inner and outer bearing plus wheel grease seals then get them repacked. Sometimes you can just have them tightened and that fixes it
Q:what kind of bearings go in a bmx rear hub?
They are probably 1/4 or 5/32 diameter balls, but the rest of your question leaves me wondering. The hubs that your bike has are quite OK for the grade of bike you have, and just replacing the bearings will have no effect- or if anything a negative effect- on the operation of the hub. Keep in mind that the bearings run on cups pressed into the hub and on cones that are threaded onto the axle, so replacing bearings on a new bike without upgrading these items is useless. By the way, my guess is that the cups and cones can't be upgraded. I suggest that you leave what seems to be a brand new bike alone and stop trying to improve on something that doesn't need it. If you have some problems, see you dealer and explain it to them- chances are any adjustments will be free (or cheap).
Q:beginner skateboard bearings?
For a beginner you should just stick with the ones the board comes with
Q:Ok i skate and my bearings are abec 1 i get on it and kick then it just stops?
Any bearings with an ABEC rating aren't worthwhile. Get a set of Bones Swiss or Reds. Bones have been around for a while and they definitely know how to make a quality product that the majority of pro skateboards use today. Bones lasts for a long time so get them if you can afford them.
Q:Do i have to get a new front hub if the bearings are broken?
It depends on what is actually wrong, and how bad it is. If there is a clicking sound coming from the hub as you spin the wheel, it could be a broken bearing. The clicking is caused by the remaining ball bearings rolling over parts of the broken one. Most cycles have cup and cone wheel bearings, but some later top end ones could have a cartridge bearing. If one or more of the ball bearings has broken, and the wheel hasn't been used much since it broke, then a new set of bearings could be fitted. The hub will need to be stripped, cleaned, checked for wear, and if there is no damage, re - built with the new bearings. If the wheel has been used for some time with a broken bearing, then the bearing surfaces in the hub may damaged, and it will probably be cheaper to replace the wheel, rather than fit a new hub. If in doubt, take the wheel to a reputable cycle store, and ask them to look at it, they should be able to advise you on the best solution.
