On ceramic ball bearings...
Same reason they are no longer on expensive bicycles...mainly pro's
that toss a $20K bike after just a few races.
Noodled it when looking and found tons of busted bearings.
Whizy Bang and the engineers fell for it without really knowing all or enough
about it
Harder than steel and can be manufactured 'rounder' than steel. Sounds cool, right?
Well..not all are pure ceramic and the blend is also important. Then hydrid
ceramic's...
Then what about the cone/cup/race/etc or if cartridge the whole thing is still steel on
many. Softer to lost if the pure benefit of going ceramic. I do not know if
the Ford Turbo's are just ceramic balls or the whole bearing assembly is ceramic
Since harder than steel...they are more sensitive to debris in the lube and most
are GREASED on bicycles. Don't know enough about the these ICE turbos, but most
are engine oil lubed
Ceramic is harder and rounder than steel...but along with that comes brittleness
and is where I've read that the Ford Turbo ceramic ball bearings turning into
dust.
Since engine oil lubed...wonder if those failed ceramic bearing's dust got filtered
TOTALLY or did some get past the filtering system and into the rest of the ICE
So passed on ceramic ball bearings on my road bike. Plus at $2.50/each ball,
a 20 ball bearing cartridge is too expensive for my budget.
