Spherical joint bearings are a sub-industry in the bearing industry. At present, the market size of my country's joint bearing industry is about 1.6 billion yuan, of which domestic enterprise sales are about 600 million yuan.
Joint bearings have unique properties such as heavy load bearing and center adjustment, so they are widely used in new energy (wind power, nuclear power), aerospace and military industry, railway locomotives and rail transit, steel structure buildings and roads and bridges, large-scale special engineering machinery, heavy-duty Automobile, water conservancy and hydropower, metallurgy and mining industries.
Special joint bearings are promising
my country’s economy is in the stage of industrial upgrading and structural adjustment. New energy, high-speed railways, large-scale special construction machinery, heavy-duty machinery and other emerging and high-tech industries have been identified as key development areas by the state. The development of these fields will give my country’s high-end joints The bearing industry brings new development opportunities. The annual import value of high-end joint bearings of 1 billion yuan also provides ample room for domestic enterprises to substitute imports.
New energy field: In the next few years, my country’s newly installed wind power capacity will continue to grow at a rate of 10-15 million kilowatts per year. Although the growth rate has slowed down, it will remain above 35%. Up to now, my country's installed nuclear power capacity is only 9.068 million kilowatts, and nuclear power generation accounts for only 2.2%. According to the plans of the National Energy Administration and the National Development and Reform Commission, by 2020, nuclear power will account for 5% of the total installed power capacity, and the total installed capacity will increase to around 70 million kilowatts. If wind power, nuclear power and other new energy industries follow the above-mentioned development speed, by 2011, the market demand for special bearings in the new energy field will reach 32 million yuan / 37,000 sets, an increase of more than 400% from 2008.
Rail transit: In the next 3 to 5 years, the growth of my country's rail transit will mainly come from the construction of high-speed passenger dedicated lines, the construction of urban rail transit, and the increase in electrification and double-tracking rates. These industries are also the most widely used special joint bearings. One of the fields. It is estimated that by 2011, the market demand for special bearings in the rail transit field will reach 35 million yuan/190,000 sets, an increase of more than 250% from 2008.
Large-scale special construction machinery: large hydraulic excavators over 30 tons, large bulldozers over 400 horsepower, new truck cranes over 100 tons, and wheeled cranes with good off-road performance, and other large-scale special construction machinery are among the key development varieties of my country's construction machinery industry. It is estimated that by 2011, the market demand for special bearings in this field will reach 240 million yuan/3.2 million sets, an increase of more than 370% over 2008.
According to the above analysis, we predict that by 2011, the market demand for special joint bearings in my country will reach 538 million yuan. Judging from the recent export situation of the bearing industry, exports are gradually improving. By 2011, the international market's demand for special joint bearings is about 200 million U.S. dollars.
