(1) Development of Global Dynamic Pressure Oil Film Sliding Bearing Subdivision Field
Based on its strong load-bearing capacity, resistance to impact and vibration, dynamic pressure oil film sliding bearings are widely used in energy equipment such as steam turbines, water turbines, nuclear power main pumps, power equipment such as electric motors, automotive engines, diesel engines, and various industrial pumps, fans, compressors, rolling mills, and other machinery and equipment. Dynamic pressure oil film sliding bearings have a crucial impact on the working accuracy, performance, lifespan, and reliability of these main engines.
At present, the sliding bearing industry is mainly controlled by large multinational corporations such as Kingsbury, Michell, RENK, Waukesha, and Miba. Due to the long development history of the sliding bearing industry in developed countries, a comprehensive technical system has been formed, rich research and engineering application experience has been accumulated, multiple high-precision manufacturing processes have been mastered, and a sliding bearing supply system led by several leading enterprises has been established. Therefore, important equipment and key supporting sliding bearings are basically from the above-mentioned large bearing manufacturers.
According to data from Sihan Industry Research Institute, the global market size of dynamic pressure oil film sliding bearings reached 1.99 billion US dollars in 2020. It is expected that the annual compound growth rate of the global dynamic pressure oil film sliding bearing market size will be 10.5% from 2020 to 2026. By 2026, the global market size of dynamic pressure oil film sliding bearings will reach 3.62 billion US dollars. Note: Includes bearing accessories
(2) Development of the subdivision field of dynamic pressure oil film sliding bearings in China
High end sliding bearings refer to sliding bearings with high performance, high reliability, and high technical parameters, which can meet the extreme working conditions and special environmental requirements of high-end and high reliability equipment or weapon equipment, and have strategic significance for the national economy and national security.
With the continuous innovation of modern and industrial equipment, high speed, heavy load, high precision, high reliability, long life, environmental friendliness, and strong adaptability to extreme working conditions and special environments have become the goals pursued by high-end equipment. In these high-end equipment, bearings are often the key basic components, and the performance of bearings has a significant impact on these key performance indicators of the equipment.
Dynamic pressure oil film sliding bearings belong to the mid to high end bearings in sliding bearings. The gap between China's dynamic pressure oil film sliding bearing manufacturing industry and foreign countries is mainly reflected in the following aspects:
(1) The self-sufficiency rate of dynamic pressure oil film sliding bearings is relatively low;
(2) A large number of products have low quality, and although some high-end products can be designed and produced, their quality is unstable;
(3) The process capability and guarantee capability of materials and manufacturing industry are insufficient;
(4) The testing technology is insufficient, and there is still a considerable gap between product experimental testing and user application data accumulation compared to foreign countries;
(5) For high-end units such as nuclear power units, the purchasing power is strong, but the relative support for domestic research and development is insufficient;
(6) Domestic enterprises have weak brand influence, incomplete service and sales network coverage, and weak customer confidence, especially among international customers.
According to data from Sihan Industry Research Institute, the market size of dynamic pressure oil film sliding bearings in China reached 3.23 billion yuan in 2020. The dynamic pressure oil film sliding bearing industry in China is still in its growth stage, with production technology and product quality continuing to improve. There is still a lot of room for expansion in the application fields of products, and the industry is expected to maintain a rapid growth trend in the future.
According to the prediction of Sihan Industry Research Institute, the average annual compound growth rate of China's dynamic pressure oil film sliding bearing market size from 2020 to 2026 is about 13%. By 2026, the market size of China's dynamic pressure oil film sliding bearing will reach 6.72 billion yuan.
