Slow development of domestic hardware bearing technology

In recent years, the overall production scale of the domestic bearing industry has continuously expanded, and the number of bearing companies has increased dramatically. Nearly half of the nearly 2,000 companies are large enterprises.

Since 2014, China's hardware bearing industry has experienced slow development of manufacturing processes and equipment technologies, low numerical control of CNC machining, and low level of automation of grinding operations. There are only 200 automated production lines in China. Most enterprises, especially state-owned and old enterprises, still have traditional equipment as their main production force. Advanced heat treatment processes and equipment that are critical to bearing life and reliability, such as controlled atmosphere protection heating, double refinement, and bainite quenching, have low coverage, and many technical challenges have failed to achieve breakthroughs. However, with the development of the market, users are increasingly demanding the accuracy, performance, and type of bearing products, which has also evolved into the market's demand for high-grade bearings. In order to meet this demand, the bearing industry should greatly increase the level and quality of bearing products.

The research and development of new steel grades for bearing steels, the improvement of steel quality, and the development of related technologies such as lubrication, cooling, cleaning, and abrasives, have not yet been able to meet the requirements of bearing product levels and quality improvement. As a result, the process capability index is low, the consistency is poor, the product processing size dispersion is large, and the inherent quality of the product is unstable, which affects the accuracy, performance, life, and reliability of the bearing.

Reviewing the development history of China's bearing industry, during the “10th Five-Year Plan” and “Eleventh Five-Year Plan” period, the technological progress of the entire industry was very obvious. In addition, the Bearing Industry Association conducted a technical breakthrough in the entire industry to ensure the product's longevity and reliability. The noise, materials and other technologies have made tremendous progress, especially small and miniature bearings. However, due to the increasingly fierce competition among enterprises, some companies are not willing to share special technologies with their peers. Such selfishness makes progress slower. some.

As a basic industry in China, the development of the bearing industry is not fast, but it already has a large production capacity. The national policy has given strong support to the development of the bearing industry. Under such circumstances, the economy of the bearing industry is gradually increasing. In today's information age, the bearing industry wants to further develop and will inevitably enter the Internet e-commerce market.

Entering the Internet e-commerce has also opened up a new market space for the bearing industry to ease the overcapacity in the bearing industry.
