The large-scale extrusion granulator is an important equipment in the large-scale ethylene complete equipment of the petrochemical industry, and its bearings are multi row series thrust roller bearings, which are technically difficult. In recent years, ZWZ Group, located in Wafangdian City, Dalian City, Liaoning Province, has successfully developed multiple bearings for the main reduction gearbox of granulators, becoming one of the few manufacturers capable of designing and producing multi row series thrust roller bearings.
In recent years, ZWZ Group has accelerated its innovation leadership, with a R&D investment ratio of 6.1%, higher than the industry average. ZWZ seized the opportunity of the country to promote the upgrading of traditional industries and cultivate strategic emerging industries, made efforts to strengthen the weak points of the industrial chain, forged new industrial competitive advantages in the process of implementing the goals of carbon peak and carbon neutrality, and fully promoted the three major projects of "piloting", "sailing" and "strengthening the foundation", focusing on the application scenarios of eight series of products such as high-performance bearing technology, focusing on wind power, shield machine cutterhead and other key industries such as steel and cement, Developed research projects and developed over 860 types of bearings with good sales, comprehensively enhancing market competitiveness.
ZWZ Group focuses on the main business of bearings, guided by market and customer demand, and has launched 12 key projects for technological transformation. It has built the largest bearing heat treatment production base in Northeast China, with a total investment of 1 billion yuan. The first production line of the wind power spindle bearing construction project will be put into operation in July this year, becoming a new growth pole for future development. ZWZ Group takes marketing as the entry point to drive the digital construction of the entire value chain of research, production, sales, supply, and service, and continuously enhances its high-end manufacturing capabilities. A shield machine cutterhead bearing designed and developed by ZWZ, achieving batch supply; We have developed and designed multiple cylindrical roller bearings without outer rings for a well-known heavy-duty gearbox manufacturing enterprise, and have started mass supply and promotion in the industry; A cold-rolled support roller bearing developed for a steel enterprise, with a total of 4000 hours of online operation and no faults; Six high-end bearings developed for an electric motor company have successfully passed customer installation and operation assessments, becoming a new increment in the future market.
Innovation is the inexhaustible driving force for the development of enterprises, and it is the fundamental factor for enterprises to climb and grow. Liu Jun, Chairman of ZWZ Group, stated that this year, ZWZ Group will fully integrate the resources of Shanghai R&D Center and European R&D Center, carry out collaborative design and research and development, target the world's cutting-edge, increase independent innovation in the technology field, and create a batch of new flagship products, providing strong support for strengthening the independent and controllable supply chain of the industrial chain.
