  Item No.: Ceramic ball bearing

Ceramic ball bearing consist of steel raceways, a retainer, a lubricant and ceramic balls.With Ceramic ball bearings rings made of bearing steel (AISI52100) or stainless steel(AISI440C)The Ceramic ball bearing is mainly made of silicon nitride(Si3N4), zirconia (ZrO2) or alumina (Al2O3), among which Si3N4 is of excellent overall performance and haS become the preferred material for ceramic ball bearing,Hybrid ceramic bearings can achieve higher speeds, greater accuracies, and have a longer service life than steel bearings which is why hybrid ball bearings are finding increased usage in a wide variety of engineered applications today.
