Large-scale extrusion granulator is a major key equipment in large ethylene complete equipment in petrochemical industry. Its core bearing is multi-row series thrust roller bearing, which is technically difficult. ZWZ Group has successfully developed three representative types of of Main Reduction Box Bearing for Granulator for well-known domestic manufacturers of extrusion granulators, which has solved the problems of domestic customers and equipment manufacturers of relevant granulators. And ZWZ has become the second manufacturer in the world that can design and produce multiple series thrust roller bearings.

(On February 2, ZWZ Group employees were assembling the planetary carrier bearing of the wind power gearbox.)

In recent years, ZWZ Group has accelerated its innovation leadership, with the R&D investment ratio reaching 6.1%, higher than the industry average. They seized the opportunity of the country to pay close attention to the transformation and upgrading of traditional industries and the cultivation and expansion of strategic emerging industries, focusing on the key technical issues of high-performance bearings, focusing on the application scenarios of 8 series of products such as wind power, shield cutter head, and other key industries such as steel and cement, and developing key projects. More than 860 types of bearings developed have been replaced by localization, which has comprehensively improved market competitiveness.

At the same time, ZWZ Group focused on the main bearing industry, guided by market and customer demand, launched 12 key projects for technical transformation, built the largest bearing heat treatment production base in Northeast China, and the first production line of the wind power spindle bearing construction project with a total investment of 1 billion yuan will be put into operation in June this year, becoming a new growth pole for future development.

Liu Jun, chairman of ZWZ Group, said that this year, ZWZ Group should fully integrate the resources of Shanghai R&D Center and European R&D Center to carry out collaborative design and research and development, aim at the forefront of the world, increase independent innovation in core technology fields, and create a new batch of competitive products, providing strong support for strengthening the independent and controllable ability of the industrial chain supply chain.
