2019 DIN 5401 chrome steel ball 55mm for yaw pitch bearing
1.The slewing ring bearing are important components of wind power generator.According to the installation location, wind turbine bearings could be divided into main shaft bearings, yaw bearings and pitch bearing etc. The life of wind turbine bearings are required to last more than 20 years as the working environment is tough and maintenance cost is very high. Therefore, wind turbine bearings have strict quality requirements on steel balls.Yusion carries out standard management systems strictly according with proprietary standard regulated by international technology criterion of steel to select our raw material.And by advanced facility, top-ranking testing intruments and stringent control procedures to guarantee our wind energy steel balls with superior quality and long life.
2.We have the world's most advanced steel ball surface quality inspection equipment-AVKIO eddy current test machine from Czech Republic & photoelectric appearance instruments to ensure our rockbit steel balls 100% final inspection.
3.Our customer all have found our S-2 rockbit steel balls is superior in quality which saves them at least 40% cost working with us.

About us
In 1993, Luoyang Daobei Special Steel Ball Plant was founded, which was a jointventure of LYC. In 2004 it started the business of wind energy steel ball with Korea company . In 20016 after reformation, it was renamed Luoyang Zhisheng Special Steel BallCo.,Ltd (ZS). And it was moved to the Yingzhuang Industrial Park of Mangshan Town, Luoyang,Henan in the same year. In 2007 its first batch of bearing balls were applied for GE wind energy bearings . In 2013 its annual output value exceeded more than RMB 35 million ,and 80% of our balls are mainly for wind energy industry. In 2014 ZS developed a new product "AISI S-2 Rockbit Ball" for oil drilling industry ,which was sold to USA and Canada markets. In 2015 it imported an AVIKO Eddy current test machine from the Czech Republic and its model 3070 is the first one in China. In 2016 Luoyang Yusion Industrial Co.,Ltd was founded, which is a subsidiary of ZS. In 2017 it Established a cooperation relationship with North America, Russia,
European oil industry giants, and a batch of photoelectric appearance test equipment was purchased.
