Flange bearings are the key components in the machinery and equipment manufacturing industry. The performance, quality and reliability of mechanical equipment depend on the performance of the bearings. After years of development, the bearing industry in China has formed a relatively mature industry scale. At present, China's bearing industry has an annual output value of 130 billion yuan, ranking third in the world. It is estimated that by 2015, the sales of the bearing industry in China will reach 222 billion yuan, and the average annual growth rate will remain at about 15%.

Although the development of China's bearing industry has achieved certain results, the current problems can not be ignored, the most prominent is the low-end products, high-end products also rely mainly on imports. The development of high-end bearings in China is seriously out of line with the development of China's machinery and equipment. What is gratifying is that some companies that have accumulated and are committed to innovation have made breakthroughs in developing high-bearing products. For example, Luoyang Zhongyue Precision Bearing Co., Ltd. specializes in R&D and production of P4 and P2 high-end precision bearings. At present, the company's machine tool bearings, spindle bearings, high-speed bearings and other market competitive advantages, especially the machine tool bearings, product quality and imported products can be equivalent.

Based on the backward development of high-end bearings in China, the "Twelfth Five-Year" development plan that has been introduced clearly states that the state will play a guiding role in industrial policies to support the development of the bearing industry. Under the guidance of the state, the access threshold for the bearing industry will increase, the high-end production capacity of low-end products will be controlled, and the research and development of high-end bearings will enter the high-speed stage.
