Ceramic ball angular contact ball bearings, silicon nitride(Si3N4) which has a high material integrity and hardness is the common material of the ceramic balls. Rolling ceramic balls are the important part of high speed bearings. Its low density materials, high rigidity and long life are the crucial factors of high speed bearings. High speed and high precision ceramic ball bearings are widely used in aviation, aerospace, marine, chemical and other fields.
