Miniature bearings are generally used with the host supporting industries, including the automotive, appliance, medical equipment and other industries, the development of related industries will drive the demand of the industry.
China's auto market in recent years has maintained a trend of rapid growth, from car ownership per capita household income, per capita car ownership and other factors to consider, cars still in the incremental market, not into the stock market. According to Prospect Industrial Research Institute released "Chinese precision spindle bearings manufacturing industry sales demand forecast 2015-2020 and upgrade analysis report" shows that the automotive industry is still holding period of high growth, future growth of not less than 15%.
With the miniaturization of electric car process, the corresponding components of products is increasing. Thus, car-related components market will continue to expand. Automotive bearings of the development, will focus on safety, improve efficiency and reduce harmful substances. Car radiator cooling fan motor, wiper motor, exhaust gas recirculation system (EGR) valve frame and anti-lock braking system (ABS) as the representative of the pump motor and its application system is the main application field of miniature bearings.
In particular ABS spindle bearing, in the 1980s, is used only for luxury cars, after which advance to the direction of miniaturization and popularity as an important product safety measures, from the mid-1990s began expanding use. At present, the development of the multi-purpose vehicle spindle, safety direction, not only for the use of ABS brakes intermittently control, but also with sensors to monitor driving conditions even move to a different drive wheel braking force all around, from the overall control safe driving. The future development trend of miniature bearings such a system is upgraded ABS system, different manufacturers have different product names such as ESC, EPS, VSC and so on.
Development of the ABS system is a typical example of the development of automotive-related products. Miniature bearings future with the increasing safety and environmental requirements, will derive many new applications. Bearing market targeting hybrid and electric cars will try to create a new type of automobile-related products. In this development, the field of miniature bearings involved will continue to expand its precision will continue to increase, with the continuous development of China's auto industry, a huge space for development of domestic enterprises.
Market size of China's home appliance industry has expanded each year, the growth rate has declined in recent years, prospective Industry Research Institute expects the market size of China's home appliance industry will continue to expand year by year.
Appliances with miniature bearings representative products are vacuum cleaners and air conditioners motor bearings, mainly the outer diameter of 22mm motors. Vacuum cleaner is characterized by its number of revolutions of the motor up to 4-5 million revolutions / min, and 100 000 turn / min motor has also been used to market a large number of sales of vacuum cleaner. The air conditioner is a long time in the device for indoor use, low noise high demands. Currently there is a problem, the power lead to galvanic corrosion between the inner and outer ring of the bearing, the solution is to use only non-conductive ceramic balls, which will enhance the miniature bearings used in home appliance technology.
In recent years, the market size of China's medical device industry to maintain rapid growth. Prospect Industrial Research Institute expects China's medical device industry will maintain a growth rate of over 20%.
In medical devices, bearings use also involves many aspects, mainly for artificial dialysis blood pump, drug infusion pump, ventilator air pump and other equipment. These devices use the pillow in bed, it must be low-noise processing. An extreme example is the use of dental dentist drill, drill 40-50 ten thousand revolutions per minute, the doctor at the treble stimulus is hard to bear. Medical device bearing a major issue is that the bearing of the drug and the acid corrosion resistance, which is a subject of the bearing material can not be separated.
From the above applications bearing the future development trend shows, miniature bearings are mainly towards sophisticated, bass and other direction, so the future direction of development of precision bearings. Given the wide range of precision bearing applications, the development of all walks of life of the bearing accuracy, performance, reliability and other aspects of life and the increasingly high demand, the number of required more and more. However, domestic production of precision miniature bearings in is still the weak link, according to the statistics, since the rate of precision miniature bearings with only 40% of the domestic had to spend a lot of foreign exchange to import precision miniature bearings annually, of which the majority of high-speed electric main spindle bearings To rely on imports. In recent years, China's domestic machine tool industry, the automobile industry has developed rapidly, to adapt to the needs of product upgrades and import substitution, our precision miniature bearings market prospects.
