The slewing bearing industry is a capital-intensive and technology-intensive industry. After years of development, the Xuzhou slewing bearing industry has initially established relatively perfect industry standards. The research and development capabilities of slewing bearing companies have been greatly improved, but compared with developed countries, they are developing and manufacturing technology development, process equipment and testing instruments. There are still some gaps in such aspects.
In Xuzhou slewing bearing products, the proportion of high-precision, high-tech and high value-added products is relatively low, and high-end slewing bearings still rely on imports. In terms of slewing bearing manufacturing technology, most of Xuzhou slewing bearing companies have slow development of manufacturing process and equipment technology, and the numerical control and automation of processing equipment are relatively low; the heat treatment process and equipment critical to the life and reliability of slewing bearings needs to be improved. The research and development of new materials required for slewing bearings and the research and development of other auxiliary materials and processes cannot meet the requirements for slewing bearing product levels and quality. As a result, the process capability index is low, the consistency is poor, the dispersion of product processing dimensions is large, and the intrinsic quality of products. Instability affects the accuracy, performance, life, and reliability of the slewing ring.
In order to expand its share in the high-end market, Xuzhou’s relatively strong slewing bearing manufacturers with capital and technical strength are continuously increasing their investment in R&D. For example, Xuzhou Jieheng Slewing Ring Co., Ltd. has been developing industry standards since 2011. More stringent corporate internal standards to ensure that the slewing bearing geometry is further improved; the depth of the hardened layer is increased; the service life of the slewing ring is increased; the research and development of anticorrosive materials is strengthened; and the application of the slewing ring is promoted; The development of equipment, the use of computer simulation technology for the effective validation of slewing ring bearing capacity, the product structure into the size of the optimization design. At the same time, many enterprises in Xuzhou slewing bearing also began to pay attention to the research and application of the slewing ring basic technology and related technologies.
It should be said that in recent years, Xuzhou slewing bearing has developed rapidly and the quality of slewing bearings is high. At the same time, combined with the continuous improvement of the company’s operating capacity and production efficiency, Xuzhou slewing bearings have always maintained a competitive advantage in the domestic market in the domestic market.
