Ceramic Bearings?

[demographic]

Anyone used them yet? Any good?

I know theres a few threads where they are mentioned but I can't seem to find any where the person has actually used them to give any feedback.
Doordie? Stewart? BDI?

I remember Doordie mentioning them in his wasted Crank thread but not heard any more about them.

The reason I am asking is because someone on another forum I go on was asking and I remembered some comments on here, anyone?

Regards Scott.

You might already know this, ceramic bearings will dissipate heat very quickly, their running surface is smoother which reduces friction and wear. I have no experince with them. In a dirt bike engine I could only see a benifit if the engine is highly modified and turns at high rpms for extended peroids of time.

Another forum?  WHAT??  Are you 2 timing us?  Could that be Visor Down?  I just rejoined their forum yesterday and saw your name in one of the threads.  I've heard about the ceramic bearings but all I know is they cost allot more.

Yup, I'm just a dirty cheat
It's not Visordown, I used that forum for ages but it rapidly went downhill after the owner sold it to a magazine, the search function was broken, and it generally went arse up and got a bit sweary.
Not used it since just after cristmass.

Quite a few of the people on there moved over to therevcounter.com and so far its OK. There the odd numpty but the moderators seem able to get a handle on it.

Cheers, Regards Scott.

I play around with chain saws on the side and here is a link to another forum that talked about these bearings. May help.

Thanks for that, I have viewed that site a few times as I was recently given a "broken"* Stihl 038 chainsaw and was looking for details on it.

Good info on the bearings as well, Can't say I am going to start using them but its all good stuff all the same.
Thanks.









* As it turned out it wasn't broken at all, it just needed the carb cleaned out and fresh petrol putting in it Chuffed to bits.

Doordie,
  The trouble is that you can really only tell if they DONT work.......Ha Ha. Cam.

No exactly,but if it spinns with less friction,you should notice at better throttlerespons and less vibration.
