With the gradual recovery of the slewing bearing market in 2018, domestic demand for slewing bearings will continue to grow in the first six months of 2019. This time, the market is recovering from the short or medium to long term. Judging from the changes in the market demand for large slewing bearings, as the domestic construction machinery enters a new maintenance cycle, the National Belt and Road Initiative is gradually implemented, the construction machinery industry is generally warming up, and the construction demand is strong. Mechanical parts are transferred to the slewing bearing market, resulting in slewing bearings. Increase in demand. What are the reasons and trends for the rise in slewing bearings? Due to the continued impact of the national production reduction policy on the steel industry, the supply of raw materials for slewing bearings is tight. The supply of slewing bearings is in short supply compared to the strong growth in market demand. From the price point of view, the market price of slewing bearings will continue to rise in the future. In recent years, emerging manufacturing industries such as smart manufacturing, industrial automation, new energy, environmental protection equipment, and amusement equipment have risen rapidly due to structural adjustments in manufacturing. The demand for slewing bearings, especially for non-standard customization and high precision, for high quality slewing bearings is growing strongly.
