ZYS Rail Transportation

ZYS has been committed to the research and development of bearings for rail transportation for a long time to meet the increasing requirements for rail transportation,such as higher speed,load,reliability and etc.

As China National Quality Supervision and Testing Center for Bearing,we are in charge of bearing quality supervision and inspection arbitration.Therefore,we can conduct simulation test and durability test on our railway bearing testers.

Professional service can greatly improve bearing performance.Therefore,we can supply professional services,like bearing mounting,removal,maintainance,application and etc.to improve the safety of vehicle running.

Our products have passed ISO 9001-2000 Quality Management Certification and GJB/Z9001A-2001 Military Quality Management Certification.

ZYS Wind power

In 2001,ZYS was China’s first company to undertake the project of “Main bearings development of large and medium size wind turbine generator system” from National Ministry of Science and Technology.Due to this project,ZYS acquired the core technology and intellectual property in designing,manufacturing and testing the yaw bearing,pitch bearing,wind leaves bearing,gearbox,and generator bearing in wind turbine system.

We have developed a professional group in wind turbine bearing design,property analyses,manufacturing and testing.Cooperating with Xi'an Jiaotong University,we cultivated China’s first postdoctor in the major of wind power generator bearing and exploited the integrated design and analysis software that can conduct load spectrum analysis of wind turbine generator bearing,stress analysis,design verification of key structural parameters,calculation of effective hardened layer depth and the verification of gear and bolt strength,etc.

ZYS wind turbine generator bearings have reached international advanced level.Up till now,we have applied many national patents in wind turbine generator bearings,such as “Slewing bearing for 1.0MW wind turbine generator”,“Slewing bearing for 1.5MW wind turbine generator”,“Self-lubricating cage for slewing bearing”,“Three-row roller combination slewing bearing with long life and high load capacity”,and “Intelligent wind turbine generator bearing based on object net” etc.In particular,the exclusive patent of “Intelligent wind turbine generator bearing based on object net” can realize remote monitoring,fault warning and trouble shooting to wind turbine generator system.http://www.zysbearing.com/wind-power.html

ZYS precision angular contact ball bearings

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.
