The large-scale extrusion granulator is one of the major key equipment in the petrochemical industry's large-scale ethylene complete equipment. Its core bearing is a multi row series thrust roller bearing, which is technically difficult. For a long time, domestic users have mainly used imported bearings from abroad. ZWZ Group has successfully developed three representative models of main reducer bearings for well-known domestic extrusion granulator manufacturing enterprises, solving the bottleneck problem of domestic granulator users and equipment manufacturers. It has become the second manufacturer in the world to design and produce multi row series thrust roller bearings.

In recent years, ZWZ Group has accelerated its innovation leadership, with a research and development investment ratio of 6.1%, higher than the industry average. The company seizes the opportunity of the country's strong focus on the transformation and upgrading of traditional industries and the cultivation and growth of strategic emerging industries, focuses on filling the gaps in the industrial chain, forging new competitive advantages in the process of implementing carbon peak and carbon neutrality goals, and fully promotes the three major projects of leading, sailing, and strengthening the foundation. Focusing on the key technical issues of high-performance bearings, the company focuses on the application scenarios of eight series of products such as wind power and shield machine cutterheads, as well as key industries such as steel and cement, formulates research and development projects, and develops more than 860 types of bearings to reach the international advanced level, comprehensively enhancing market competitiveness.

At the same time, 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 a large bearing heat treatment production base in the Northeast region, 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; Accelerate digital empowerment, use marketing as the entry point to drive the digital construction of the entire value chain of research, production, sales, supply and service, and continuously enhance high-end manufacturing capabilities. A certain model of shield machine cutterhead bearing designed and developed has been recognized by customers, reaching international advanced level and achieving batch supply; We have developed and designed multiple cylindrical roller bearings without outer rings for well-known domestic heavy-duty gearbox manufacturing enterprises, and have started mass supply and promotion in the industry; The cold rolling support roller bearing developed for a certain steel enterprise has been running online for a total of 4000 hours without any faults; Six models of high-end bearings developed for a certain motor enterprise have successfully passed the customer's installation and operation assessment, becoming a new increment in the future market.

It is reported that this year, ZWZ Group will fully integrate the resources of Shanghai R&D Center and European R&D Center for collaborative design and research and development, aiming to increase independent innovation in core technology fields at the forefront of the world, and create a batch of flagship products to provide strong support for strengthening the independent controllability of industrial and supply chains.
