ZYS precision angular contact ball bearings consist of high-precision angular contact bearings (standard series),super high-speed angular contact ball bearings,high-speed sealed angular contact ball bearings and high-speed spindle bearings.
The inner ring,outer ring and rolling elements of bearing under normal working conditions are made of high carbon chromium bearing steel.To meet the special requirements,such as super high speed,wear-resisting,low temperature rising,long life and high reliability etc.,it’s suggested to use hybrid ceramic ball bearings.

ZYS precision hybrid bearings with ceramic ball (HQ1) can significantly improve the speed,rigidity,reliability,and productivity of machine tools,and greatly reduce the friction heat,then extend the service life of host machine etc.
Spindles also play an important role in improving the production efficiency and machining quality.Up to now,ZYS has developed 8 groups,20 series and more than 200 varieties of high-frequency spindles.The rated speeds are from 1,500r/min to 150,000r/min.High-speed precision bearings and air static pressure bearings are used as main support.Lubrications include grease,oil mist,oil gas,etc.
