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. If you are looking for 07087x bearing

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.
