Hybrid Ceramic Ball BearingsHybrid Ceramic Ball Bearings performanceThe inner ring，outer ring and rolling element of bearing are made of high carbon chromium bearing steel under normal operating,Website:://.zys-bearing.com,but the steel bearings cannot meet the requirement of such special conditions as high speed ,wear resisting,low temperature rise,long life,high reliability,etc,then SiN4 ceramics are belived to be present optimum rolling bearing materials to replace bearing steel.ZYS offers widely used hybrid angular contact ball bearing for spindles in high speed precision machine tools and other high speed precision machines,The inner and outer ring are made of high quality bearing steel ,rolling element are made of Si3N4 ceramics.ZYS hybrid bearings with ceramic balls(HQ1) can significantly improve the speed,rigidity，reliabilityand productivity of machine tools，and greatly reduce the friction heat，extend the service life.The types of ZYS hybrid bearings can be divided into H719C(AC)/HQ1, H70C(AC)/HQ1, B70C/HQ1, B70C(AC)-2RZ/HQ 1, B719C(AC)-2RZ/HQ1, etc.
