I'm posting this here, because I figure a lot of you guys have dremels
and are used to fixing things. So, can the Dremel motor bearings be
replaced? Mine goes crazy above 1/2 speed. And where can I get the
bearings?

I doubt you will be able to replace the bearings on your Dremel for less than the cost of
a new tool when you factor in your valuable time and fuel. However, I am also one who
will spend US$300 in time and money to accomplish almost as much good as tossing the old
tool and buying a new one for US$50. Just Because.

When in doubt, ask the Horse, because the problem may not be bearings:

Bring the bearings to your local bearing supplier to get them matched.
Be sure to mention that you will run them at 40,000 RPM.

I guess Dremel sells the armature and bearings as an assembly because pressing them in
place is done easier at the factory. 26 bucks for the assembly or thirty for a new tool
and accessories on eBay. Hmmmm.

It may be that the bearings are loose in the housing. new
housings are cheaper than the rotor assembly, and you can
even try shimming them - with paper etc. /mark

The front bearing on mine is shimmed with a strip cut from an aluminum
pie pan . It was too loose to get a decent finish when I used it as a
(light duty) toolpost grinder . Does fine now .

Good question. Last time I tried getting bearings, the local supply house
couldn't match them up- the sizes skip in the bearing catalog. Theyu must be
made-to-order. Dremel won't sell just the bearings- I had a rather lengthy
correspondence with some high mucky-muck at Dremel about that. They were
nice enough to send me a coupon for my next purchase.

I shimmed them with some Scotch tape. No vibration at high speed
now. Thanks.

I think that was the most positive and uplifting post of the day...

Glad it worked, too.
