Ceramic material balls are excellent alternatives to traditional steel balls and have many advantages, especially in high-speed applications. Ceramic balls represent an ideal combination in terms of density, resistance and life. Thanks to the low density of the ceramic material, 40% of that of steel, the balls develop lower centrifugal forces that result in reduced contact friction thus enabling higher speed and durability.

Friction due to rolling elements in hybrid bearings is lower than in steel-ball bearings. Therefore, hybrid bearings need less quantity of oil for lubrication. These favorable characteristics result in a significant reduction of absorbed power.
