Model Selection

　　In order to meet the high performance requirements of high speed precision applications,LYZYC has developed HCG719 series andHCG70 series of ultra-high speed super precision angular contact ball bearings.In contrast to the high speed HCS series,HCG series bearings have higher speed performance and higher capacity.

　　HCG719 series and HCG70 series bearings are used in high speed CNC,high speed engraving and milling axes,high speed electric spindles for internal grinding machines,ultra-high speed motors,molecular pumps.etc.,with high reliability and excellent precision,making them the first choice for demanding applications.

　　HCG719 series(open type):We can offer inner diamater8MM to 100MM;

　　HCGS719 series(sealed type):We can offer inner diamater 20MM to 100MM

　　HCG70 series(open type):We can offer inner diamater8MM to 120MM;

　　HCGS70 series(sealed type):We can offer inner diamater 10MM to 120MM

　　Precision:P4,P3,P2
