klein bb bearings

I have used some 6003 2rs ceramic bearings in the past in the superchargers I rebuild at work. They are great for high rpm as they do not expand like steel does when heat is generated by high speed and do not corrode like steel ball and race items. However, they do not like impacts and are prone to catastrophic failure, especially if they are subject to a load in a horizontal plane.... Stick to the old skool FAG or SKF items 6003 2RS C3.
A Japaneese company called IKO offer bearings packed with different grease formulas for different applications.

Thats what i'd heard too. Was not sure if true. But you have confirmed it.
