From the perspective of international situation and bearing import and export: affected by the Sino US trade dispute, bearing, as a key basic component, included 96.5% of the product trade volume in the list of 34 billion US dollars of additional tariff imposed by the United States on China on July 6, 2018. From July, affected by the additional tariff, the number of export bearings slowed down significantly faster than the trade volume. In 2019, China's bearing exports began to show negative growth.

The export slowdown of major enterprises is significantly lower than that of the whole country, which shows that the tariff imposed by the United States has a great impact on the export of general bearings and low-end bearings that win by price.

From the perspective of the bearing import trend, affected by the Sino US trade dispute, the key period of national economic restructuring, the ongoing capacity reduction, the low period of national macroeconomic operation and other factors, the demand of China's manufacturing industry, especially the high-end manufacturing industry has declined, and the bearing import has declined significantly.

According to the development of the bearing industry this year, at the beginning of the year, it is predicted that the bearing industry will grow by 3-5% in 2019, and the bearing export will grow by 5%. At present, it has not been realized, especially due to the impact of the Sino US trade dispute and the deep integration of the automobile industrial structure.
