Zirconia ceramic balls retain some performance relative to metal material as follows,so it has been used widely in ceramic bearing:
1,High corrosion resistance, this means they can be also used in acid and alkali .
2,High temperature resistance. Can be used up to 500℃.
4, Low density(6.05g/cm3), it is approximately 20% lighter than steel balls, running more quieter and more long live time.
5, The self-lubrication of Zirconia ball bearings makes it can be used in vacuum and high temperature conditions without lubrication.
Application fields：high precision ceramic bearings, high temperature bearings, vacuum bearings, ceramic valve ball and so on.
