Research and development of new bearings
June 17, 2021-Saint-Gobain has developed a new type of bearing that makes it easier for automakers to provide end users with the comfort they need. This innovative technology perfectly combines the low friction performance of PTFE-lined sliding bearings and the radial spring characteristics of the tolerance ring. For automobile manufacturers, the installation of this universal self-tightening bearing is very convenient; for end users, the use of this bearing can get rid of the annoying passenger cabin noise and easily adjust the mechanical devices, thereby achieving a pleasant driving Experience.
Christoph Wirtz, Marketing Manager of Saint-Gobain Bearing Interiors, said: “We are very proud of our extensive cooperation with major automakers over the years. For this reason, we are deeply aware of the various challenges our customers face, such as In the design process, torque and abnormal noise cannot be taken into account. Our innovative bearings make up for this shortcoming, and can ensure a constant sliding force under varying loads, tolerances and offset compensation, and maintain a constant sliding force during the life of the bearing Zero gaps to minimize abnormal noise. We are happy to share this innovative technology and look forward to working with partners to design new systems to improve user comfort."
This controllable new low-friction bearing has zero clearance fit under various tolerances of the mating parts, and its spring characteristics significantly expand the possibilities of shape design. This provides a lot of opportunities for automakers to continuously improve the driving experience of end users. As drivers drive longer, their demands for interior comfort are also increasing. Compared with the quality of car seat cushions, comfort can affect the overall driving experience of the driver. In addition, annoying noises such as abnormal noises and time-consuming and labor-intensive mechanical device adjustments also increase the commuting pressure of the driver.
The impact of new bearings on product name in the automotive industry
The 368a 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 368a 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 368a 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 product name 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, product name 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 product name 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 product name 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 368a bearing can only be solved by using non-conductive ceramic balls, which will improve the technical level of the 368a bearing for household appliances.
The impact of new bearings on product name 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 product name 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 368a 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 product name 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 product name, the development of various industries has increasingly higher requirements on the accuracy, performance, life and reliability of product name, 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 368a bearing products have a broad market prospect.
