At present, the basic competition pattern of the domestic market in the slewing bearing industry is: two types of enterprises have advantages in the competition. The first is joint ventures or cooperative enterprises with well-known foreign companies and wholly foreign-owned enterprises. Their product technology and production equipment are more advanced and competitive. Strong, mainly for foreign or foreign-funded main engine enterprises, and has certain advantages in the industrial application of new slewing bearings; the second, domestic enterprises that have been engaged in production and operation for a long time and have a certain scale in the country have a relatively rapid increase in production capacity. The brand reputation is high, the advantage is obvious in the competition, and it has begun to get involved in new application areas of the slewing bearing industry.

In order to expand their share in the high-end market, my country’s slewing ring companies with relatively strong capital and technical strength are constantly increasing their investment in research and development. For example, they have formulated internal corporate standards that are more stringent than industry standards to ensure the geometric accuracy of slewing bearings. Further improve; increase the depth of the hardened layer and increase the service life of the slewing ring; strengthen the research and development of anti-corrosion materials to promote the expansion of the application field of the slewing ring; develop some test equipment and use computer simulation technology to carry out the bearing capacity of the slewing ring effective verification of slewing bearings, optimized design of product structure size; at the same time, these companies also began to pay attention to the research and application of slewing ring basic technology and related technologies.

Currently, my country’s slewing bearing products are mainly supporting the construction machinery industry, and their applications in new fields such as wind power generation are showing a momentum of rapid development. Judging from the operating conditions of my country’s construction machinery industry over the years, the characteristics of periodic fluctuations are relatively obvious, which affects the market supply and demand of slewing bearings. At present, the market’s demand for slewing bearings has increased significantly, and the slewing bearing industry has developed rapidly.
