Ceramic balls can be found in a variety of materials. The best material available - and the one used for our bearings - is silicon nitride (Si3N4). 

Ceramic balls are superior to steel balls in all physical measurable properties. This ensures many benefits in the bearing: The increased hardness of the ball means that the contact area between the ball and the track is reduced leading to lower friction, higher potential speeds, and less energy waste. The hardness and the extremely smooth surface also mean that the balls are far more durable than steel balls.
