Full ceramic bearings are 100% ceramic. Balls, rings and retainers. The density of ceramic is 40% that of steel, the resulting reduction in weight reduces centrifugal forces imparted on the rings, reducing skidding, allowing up to 30% higher running speeds with less lubrication
[email protected]
Because ceramic balls are only 40% as dense as steel balls, the centrifugal load that they generate is less and the internal bearing friction is lower. The lower density and friction enables cooler running under the same operating conditions, or even higher rotational speeds

lead-solder balls that collapse during reflow attachment to the printed wiring board. By contrast, ceramic BGAs employ higher temperature, non-collapsible 90/10 Pb/Sn solder. Solder-ball and solder-mask composition should be chosen to optimize the adhesion of the solder balls to the laminate and to the host printed wiring board
