The development of high-speed bearings is the shortcoming of Chinese bearing industry. After the establishment of ZWZ’s National Large Bearing Engineering Research Center, the company improved high-speed bearing testing platform, formed high-speed bearing development project group, and accelerated the high-speed bearing development. A variety of specifications of high-speed wire rod finishing rolling mill unit bearings has been produced successfully under the joint efforts of engineers and technicians. All the indicators has met the customers’ requirement through tests and the speed has reached 17000rpm. The successful development of the bearing will break the long-term technological monopoly.of imported products and foreign enterprises in domestic high-speed wire rod finishing rolling mill unit bearings.
Now ZWZ has produced high-speed wire rod finishing rolling mill unit bearings with many specifications. During the development process, the company has also realized universal matching of angular contact ball bearings, laying the foundation for the future development of high-speed bearings
