Are ceramic bearings better?

I hate to ask, but here goes...are the bearings location specific? and temp restrictions? are they usually caged type..install with ease?
I ask temp because they are in a blower I have, and they shattered once, and a wheel would be a different load and temp(air flow + not in a oil bath)...are they standard in a turbo? Lighter for the unsprung factor seem to be a plus...
Thanks Ryan

Ryan, I don't know all the answers. I know that you'll see them in turbos. The ones used in the wheels are ball instead of a caged roller. Dave at world wide can likely answer those questions. These are the street versions that are sealed. There is some that are in use that are not sealed. They just oil them before each pass, the seals are too much of a drag for them...
Installation was just like any standard bearing.

Wee, is right there is no way ceramic bearings will get you 3 tenths unless your stock bearings are almost seized. Maybe 1/2 tenth. and 1 mph.
Well all a guy needs is a set of stock wheels with stock bearings and the addition of the Marvy wheels and ceramic bearings should shave .7 to .9 tenths.... Would like to see the run myself...
What was sad was last night I watched a turbo busa run 10.50s (3 of them) and a ZX run 9.5's (ended up winning the night over another 9.5 Busa)

well from what I have read here..
wheels over .5 decrease in ET (still been unable to verify that)
another .2 or .3 from bearings? that would make up to a .8 decrease in ET...
I am ultra skeptical (or should I say non believer) that a guy can get that much out of a bearing/wheel combo..
I did ask a couple prostock bike builders and they are somewhat skeptical too.. (I think they are reserving comment as "stock" and "Pro Stock" are two different animals)
If I had a set of wheels/bearings, I have a couple solid ET racers I would sure like to try them on..

all those that cannot afford them, find it hard to believe they will cut any time and free up any power....those that have them say they work.
less friction is always good.
less hp lost to friction is always good.
are they worht the money, well that up to your checking account.....but the facts are clear, they work. they are better than stock.

Afterhours how much et did you pick up in the 1/4. I assume you have data that says they work. I've talked to plenty of guys that money is not an issue and they don't pick up hardly anything. maybe .10 to .15 with ceramic bearings in the wheels and motor. maybe .05 with just wheel bearings.
Ive seen this on wheels on cars. the difference between old used bearings and new bearings, also how much gease is packed into them. I'm all for less drag and friction but worring about wheel bearings is a stretch for me. That and the cost is way to high for any gains.
A stock wheel w/stock rotors vs. a aftermarket
wheel w/aftermarket rotors...I know that they
are MUCH better than standard bearings, but
I would like to see stock vs. stock...same weight
wheels and rotors.
Also would have like to see the axle torqued
to see if the side load has any effect.

NIce catch.
Good point, did BOTH wheels have NEW bearings ???
