Have high temperature resistant, resist chemical, heat conductivity are good, mechanical strength high.
Along with economical and the fast development of science and technology, the performance requirement to manufacturing mechanical components material
More and more higher.Such as bearing will be in operation under high temperature and high pressure environment, and bearing material performance
Quality is the Fundamentals of service life and the work efficiency affecting bearing.In recent years, along with work
The development of industry technology, people it is also proposed the highest wanting to the performance of bearing material
Ask.Ceramic metal bearing has a premium properties that common metal bearing is incomparable, high temperature resistance,
Intensity high abrasion, corrosion-resistant, every field has obtained increasingly extensive application.City at present
The most all increase for having high-strength wearable oxide base cermet bearing demand on Chang, but do not have
There is corresponding product the most corresponding.Rare high-strength wearable oxide base cermet on domestic market
Bearing, sells on a small quantity and public praise is preferably substantially imported product, and the market of home products accounts for
There is rate less.To this end, we set about from formula and the technique of product, develop new high-performance material
