Following on from Johnnymac's comment regarding bearings this is interesting possible .
In my investigations I was advised against partial ceramic as the possible impact could fracture the balls
There is still the problem with the steel outer and inner with water etc
Fully ceramic would perhaps get over the water problem but the ceramic outer is not designed to be press in tight fit as for steel outer and can fracture .
As I said will be interesting to hear as to how they stand up and for interest what was the cost of the 3 x ceramic as I was led to believe they talk in telephone numbers regarding price .
