Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance, even under difficult operating conditions. A hybrid ceramic design typically increases bearing stiffness by 15 to 20% compared to all-steel. This allows increased cutting accuracy, as the spindle deflects less under load. Overall vibration is also reduced. As running speed increases, ceramic balls run cooler than conventional steel balls
