Better bearings?

[Michelinho]

Hi capthook,

You can get all kind of bearings on Ebay and the prices are ok. If you want bearings with less drag, wash the grease out and use light oil as lubricant. Cuts the drag by much.

Take care,

Michel

night - thanks for the additional pic/description.  Cool idea in theory.  How to keep it perfectly centered as well as keeping the center mags rotating field from grabbing the end of the sides mags would be (some) of the problems to overcome?

Love to see a build!

Michel - good idea.  The flange bearings I got are sealed but has a grease port plug.  I tried to mix in some light oil - didn't help.  Guess I should try washing it out - thanks

X00 - yo!  Yea - ceramic bearings are SICK expensive!  You can go with just the ceramic balls - much cheaper (relative - $35 each and more).  Or go with a full ceramic unit.  Check this one out....
I guess you have really answered my question.  Want the best bearings... pay out the ass! 
I need 8 bearings (or 4 min.) - so maybe I should try the low-end model of ceramic balls for now....$$$
thanks

P.S. think I'll call vxb Monday and see if they can't offer some ideas on what might be comparable to Swiss Bones for a reasonable cost.

If you find a scrapped bicycle, and cut off the crank holding one of the
pedals, you have an astonishingly good bearing system. (Some small
or childrens bicycles have a nylon bearing of limited value).

Obviously, new pedals can be bought.

It is a shaft of length about five inches with a very good bearing at
each end, and the system is secured to the crank which could be
of further use.

These bearings will take a 15 stone man standing at a lever of around
9 inches. That is some torque.

The magnets I ordered are not going to work because they will have to be radially magnetized as first pictured to work except for the end magnets on the shaft that will be used to keep the wheel centered. They need to be magnetized as ordered but the id needs to be just larger then the od of the magnet attached to the wheel.

I just was playing with some other ones I already had and I found that it is too hard to keep them center the way they are magnetized.
