Will the 07087x bearing be replaced by the NTN Hydrogen Embrittlement Resistance Bearing brings

Will the 07087x bearing be replaced by the NTN "Hydrogen Embrittlement Resistance Bearing" brings?

NTN (hereinafter referred to as NTN) has developed a "hydrogen embrittlement resistant bearing" that has a lifespan that is more than three times longer than that of NTN standard bearings by combining new steel materials with special heat treatment technology to deal with early bearing damage caused by hydrogen elements.

In the face of a major change in the automotive field, as electric vehicles are developing in full swing, the market demand for more efficient power transmission devices is increasing, such as reducing the amount of lubricating oil in the device and reducing oil viscosity. Measures put the bearing under more severe lubrication conditions. Bearings run under severe conditions that have never been experienced so far, and there are early damages. The reason is the hydrogen embrittlement phenomenon caused by the penetration of hydrogen atoms into the steel material, which causes the strength of the steel material to decrease. In response to this phenomenon, we must seek a solution.

NTN\'s recently developed [Hydrogen Embrittlement Resistance Bearing] uses new steel materials and newly developed special heat treatment technology to suppress early damage caused by hydrogen embrittlement and is a product that has achieved a long life. The surface layer of the bearing raceway using the new steel is scattered with a lot of hard and fine metal compounds. Under the thin lubrication condition, it is not easy to wear even if the metal contacts and the exposure of the new metal surface*1 that generates hydrogen atoms is suppressed. In addition, even if hydrogen atoms are generated, these fine metal compounds can suppress the penetration rate (diffusion) of hydrogen atoms inside the bearing. As a result, the life of the developed product has been increased by more than 3 times*2 compared to NTN standard bearings. In addition, the quenching in the special heat treatment process adopts nitriding treatment to increase the nitrogen concentration of the bearing raceway surface, which suppresses the development of bearing fatigue, improves the resistance to foreign matter, and realizes the long life under the condition of foreign matter mixed in and lubricated.

In addition, the new steel uses ingredients that reduce CO2 emissions during the heat treatment process, reducing the burden on the environment.

NTN will promote this development to the world to help further improve the reliability of automobiles and industrial machinery.

The impact of new bearings on 07087x bearing in the automotive industry

The 07087x bearing is mainly used to complement the host industry, including automobiles, home appliances, medical equipment and other industries. The development of related industries will drive the demand of the industry. China auto market has maintained a trend of rapid growth in recent years. Considering factors such as car ownership, per capita income, and per capita car ownership, cars are still in the incremental market and have not been transferred to the stock market. According to the "2015-2020 China Bearing Manufacturing Industry Production and Sales Demand Forecast and Transformation and Upgrade Analysis Report" released by the Foresight Industry Research Institute, the high growth rate of the automotive industry will continue for a period of time, and the future growth rate will not be less than 15%.

With the process of miniaturization and electrification of automobiles, the corresponding component products are constantly increasing. Therefore, the automotive-related parts market will continue to expand in the future. The development of automotive bearings will focus on safety, improving efficiency and reducing harmful substances. Automobile radiator cooling fan motor, wiper motor, exhaust gas recirculation system (EGR) valve frame and anti-lock brake system (ABS) represented by oil pump motors and their application systems are the main application areas of miniature bearings.

In particular, the 07087x bearing for ABS was only used for high-end cars in the 1980s. After that, it was used as an important product for safety measures in the direction of miniaturization and popularization, and its use has been continuously expanded since the mid-1990s. The automobile spindle developed at present is developing towards multi-function and safety. It not only uses the 07087x bearing to control the brake intermittently, but also links with the sensor that monitors the driving situation, and transmits different braking forces to the front, rear, left, and right wheels. Control safe driving as a whole. The future development trend of miniature bearings. This system is an ABS upgrade system. Different manufacturers have different 07087x bearing such as ESC, EPS, VSC and so on.

The development of ABS system is a typical example of the development of automobile-related products. In the future, 07087x bearing will derive many new application products with increasing requirements for safety and environmental protection. The imported bearing market aims at hybrid vehicles and electric vehicles to try to create new types of car-related products. In this development, the field of miniature bearings will continue to expand, and its precision will continue to improve. With the continuous development of China\'s automobile industry, there is huge room for domestic enterprises to develop.

The impact of new bearings on 07087x bearing in the home appliance industry

The market scale of China household appliance industry has been expanding year by year, and the growth rate has declined in the past two years. The Institute of Foresight Industry predicts that the market scale of China household appliance industry will continue to expand year by year.

The 07087x bearing for home appliances represent motor bearings for vacuum cleaners and air conditioners, mainly motors with an outer diameter of 22mm. The characteristic of the vacuum cleaner is that the rotation speed of the motor is as high as 40,000 rpm/min, and the motor of 100,000 rpm/min has also been used in vacuum cleaners sold in large quantities in the market. Air conditioners are equipment used indoors for a long time and have high requirements for low noise. The current problem is that the electrical corrosion caused by the electrical connection between the inner and outer rings of the 07087x bearing can only be solved by using non-conductive ceramic balls, which will improve the technical level of the 07087x bearing for household appliances.

The impact of new bearings on 07087x bearing in the medical industry

In recent years, the market scale of China medical device industry has maintained rapid growth. The Prospective Industry Research Institute predicts that China medical device industry will maintain a growth rate of more than 20%.

In medical equipment, the use of 07087x bearing also involves many aspects, mainly used for blood pumps for artificial dialysis, drug injection pumps, and air pumps for ventilators. These devices are used on the pillow side of the hospital bed, so they must be treated with low noise.

An extreme example is the dental drill used by the dentist. The drill bit is 400,000 to 500,000 revolutions per minute, which is difficult for the doctor to bear under the stimulation of the high pitch. A major issue in the name of medical device products is the corrosion resistance of the 07087x bearing to chemicals and acids. This is an issue that cannot be separated from bearing materials.

From the future development trend of bearings in the above application fields, the 07087x bearing are mainly developed in the direction of precision and bass, so the future development direction is the name of precision products. In view of the wide application of precision 07087x bearing, the development of various industries has increasingly higher requirements on the accuracy, performance, life and reliability of 07087x bearing, and the number of requirements is also increasing. In recent years, China domestic machine tool industry and automobile industry have developed rapidly. In order to meet the needs of product upgrading and replace imports, China precision 07087x bearing products have a broad market prospect.
