Ceramic balls—Saint Gobain Advanced Ceramics, booth D-427 - Machine Tool Components and Accessories

According to the manufacturer, Cerbec ceramic balls for bearing applications last longer and provide better performance than steel bearings because of their inherently lower thermal expansion; smoother surface; increased hardness and stiffness; lighter weight; and corrosion/electricalresistant properties. These attributes recommend the use of these ceramic balls for bearings, linear guideways and machine tool spindles.
