can anyone comment about the performace and durability of ceramic bearing ? I learnt that some workshop supply the cermic balls and we could make up the bearing by ourself, anyone who know about this ? thank you

its the way to go free s motor or car up, much more durable. not sure about making them your self let me know if you find anything, if not boac bearings are the way to go.

isn't it suppose to be "boca"?

what is boca ? thxs

the site is http://bocabearings.com/

so I would assume that it is spelt boca-heheh

you are correct Jason!

I believe it's Boca because that is where they are located... Boca Raton Fla.
