   Bearing dimensions and technical parameters          Â
      The ZYS precision angular contact ball bearings for spindles, have four size series,718,719,70 and 72. Withthe same inner diameter, the outer diameters and the widths of 718,719,70 and 72 series increase in turn.
       ZYS precision angular contact ball bearing with 15 ° (C) and 25 ° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore ,the spindle, with high speed and small axial load ,should adopt the 15 ° angular contact ball bearings,whereas the 25 ° angular contact ball bearing should be adopted.
Types and performances of angular contact ball bearings Â
    ZYS precision angular contact ball bearings with high-speed angular contact bearings (standard series), super-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings.

ZYS Luoyang Bearing Science And Technology Co.,ltd.                                       Â
ZYS Tenet: To lead the science and technology development of bearing industry and to improve the world'sequipment level.
ZYS Spirit: To keep continuous improvement, to pursue brilliance.
ZYS Core values: Integrity, rigor, innovation, mutual benefit.
     ZYS was formerly known as Luoyang bearing research institute, which was founded in 1958 and was the only first-class comprehensive research institute in China bearing industry. As it became one member of China National Machinery Industry Corporation in 1999, the former institute was transformed into the science and technology enterprise. Then Luoyang Bearing Science & Technology Co., Ltd. was established in 2001. It was listed at Shenzhen Stock Exchange with stock code 002046 in 2005.
  ZYS Advantage  Â
     ZYS has a strong strength of manufacturing high-precision and high-reliability bearings and relevant parts. ZYS company not only possesses advanced bearing manufacturing equipments and international first-class measuring instruments,but also has strong strength of manufacturing,inspecting and testing the high-precision and high-reliability bearings and relevant spare parts.In the meantime,it always keeps a leading position in bearing basic theory,lubrication technology,design,material,test,information criterion and other aspects.
