Default Ceramic vrs Stock bearings???

Hello,

I have a MBX5R. Just wondering, is there is a big advantage getting the ceramic bearing kit over the stock bearings??

Do they last longer etc?? Any info will help, thanks

Kevin.

I would not say it is a big advantage, but they will probably last longer. They are actually unnecessary in my opinion.

Now ceramic bearings in the motor is a different story, I highly recommend them in the motor. The motor spins a whole lot more revoluitons than the drive train. At least 14 times as many on most buggies and 16 times those on a truggy.

in the motor. definately

everywhere else in the car, just standard yellow seal Avids. they get dirty too quickly so ceramics are just a waste of money imo

I am leery about a ceramic front, those seems not to seal until the engine comes up to temp, so you are runnin lean for awhile, I know I had one in a quality mill, it ran warm and leaked until the temps got up to normal, the rear bearing seems to be a big help, I went back to stock on the front. I will run Ceramic Clutch bearings, for a long main 45min-1hr, I have run them on the C-diff and on the inner ones in the front/rear diff, it seems to let it spin with less resistance, I dont run em on the out drives or the wheel ends...they do get to dirty, IMO...

Yup, ceramic rear bearing in the engine. Standard NR or RB up front. Avid Revolutions on the chassis.

Usually my cars bearings get killed by grit and dirt getting past the seals. My bearings would last a year if they stayed clean. No point in useing ceramic on the chassis.

you can take avid bearings, and pop the seals off clean the grease out and put 2 drops of trinity bearng oil in them and they will spin freely like ceramics, and last longer than those with grease because they build less heat.

Ceramic bearings and dirt do not mix. I would not waste me time with ceramic bearings in an offroad car. Like said above I would only use ceramic bearings in the engine/ and +1 on the avid revolutions, rubber seal to the dirt side and metal shield in.

I've run the premium Acer ceramics in 3-diff chassis now. I won't be doing it again.

Quality steel bearings spin just as free if you use a thin lube in them and they actually last a little longer.

Ceramics + abrupt impacts + dirt don't mix.

The only way they will live is if you service/clean them every other race weekend basically. Cost vs. Return is too small...put your money elsewhere.

ceramics are just that a waste of money and time been there
done that Avid Revolutions all the way at a buck each no more
wasted time cleaning just put a fresh ones in and your good to go

I never clean my bearing either, for a $1 each it easier to just toss and put in a new one.

Does any one use ceramic on your clutch ? I was thinking about that, but still have a lot of standards to use up first.
