Default Ceramic Bearing VS Normal Bearing

This type of ceramic REAR bearing enables a very high rotation speed. The low density of the ceramic balls makes the crankschaft’s rotation easier at high RPM. The ceramic bearing’s longevity is also widely superior to a normal bearing.
I advise it for high competition.

I'm assuming you mean internal ceramic bearings?

Do you know if ceramic bearings exist for the exterior bearing as well?

Ceramic balls type to grant a longer lasting of the Balls together with a better fluency, all this for a Better acceleration and fuel consumption.

I wonder if the ceramic bearings take the heat well or not?

yeah i've built a hyped up NSR with front and rear ceramics once. it worked very well, and was the quickest car at my track at the time. but i wasn't the quickest driver over 5 minutes though

i also did a few other light legal mods to it.

heh! I am sceptical of ceramic stuff, from my experience with a ceramic turbine wheel on my car which went 'pooof' at high boost .........twice.

Anymore experiences with other brand of ceramic bearings? I need to rebuild my V12 Rody so doing some homework before hand.

Ceramic and quality are not 1-to-1. Ceramic only refers to the material. There is a lot more that goes into a bearing besides just the material the bearings are made of.

To startoff with, smoothness (i.e. the ABEC rating) differs even among ceramics. You can easily buy cheap ceramic bearings with low ABEC ratings. They'll be cheaper than steel with a high ABEC rating.

There are also tons of hybrid ceramics. In other words, the race is made of steel while the balls are ceramic. Is it considered a ceramic bearing if both the race and balls are ceremic or just the balls? It's a matter of marketing.

That being said, ceramic is lighter and does not rust, unlike steel. Corrosion resistance plays a role in bearing longevity so ceramics can last a little longer in that regard.

Bottomline is, if it says ceramic, take a closer look. Not all ceramics are the same.
