In recent years, cars have undoubtedly become high-frequency vocabulary in Chinese and German diplomacy. In April of this year, Chinese President Xi Jinping and German Chancellor Merkel participated in the signing ceremony of three Sino-German cooperation projects: the cooperation group of BMW Group and Brilliance Group deepened the cooperation memorandum, BAIC Group and Daimler expanded the Beijing Benz capacity cooperation agreement, Volkswagen and FAW/SAIC signed a joint statement in the forward-looking technical field to continue to strengthen cooperation. Iron Shielded Deep Groove Ball Bearing
Iron shielded Deep Groove Ball Bearing is one type of ball bearings. shields are non-contact metallic (carbon or stainless steel) devices which allow high-speed operation but offer limited protection against the ingress of moisture and dirt. but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up. Iron shielded deep groove ball bearings often have steel shields installed on one or both sides and are pre-lubricated with grease. While many different retainers are available, pressed steel cages are most commonly used.
Bearing dust shields have been available almost as long as ball bearing itself. Shields are needed to stop the grease lubrication used in these bearings from leaking out. This is particularly important in applications where grease leakage may contaminate the product. The main impetus towards shielded bearings comes from the growing use of [sealed-for-life" bearings in items such as white goods, cars and power tools. Shields are fitted in the outer ring and do not make contact with the inner ring, but form a narrow gap with it.
Depending on the bearing design, series and size, MANU supplies shields in different designs.
With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides; Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for shields.
Celarance:
Internal clearance provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.
Tolerances
The standard version of our single-row deep groove ball bearings has the tolerance class P0
(designs with tighter tolerances available upon request)

After half a year, in early October, during the visit to Germany, Premier Li Keqiang once again opened a deepening cooperation journey between the Chinese and German automobile industries. In the signed US$18.1 billion bilateral trade order, auto-related projects such as FAW-Volkswagen and Beijing Benz have become the highlights. It can be said that Premier Li Keqiang’s visit shocked the entire German auto industry. In addition to witnessing the signing of the expansion agreement between BAIC and Daimler, Premier Li Keqiang also stressed in his article that China will actively consider the request of Volkswagen to increase the proportion of shares in the FAW-Volkswagen joint venture. In addition, both Chinese and German companies have made substantial progress in the field of electric vehicles and vehicle networking.
Today, although the Chinese auto market has bid farewell to the rapid development in the past, compared with the current downturn in the emerging auto market, the decline in the market in South America and Russia, and the weak recovery in the European auto market, the current steady growth of the Chinese auto market is undoubtedly still attractive. Force, German car companies will also have a chance to make a big impact in the Chinese market. Volkswagen China executives have said that the Chinese market will become an important market for the public to achieve future strategic goals. In my opinion, the cooperation between Chinese and German auto companies has clearly entered the "honeymoon period" this year.
With the increasingly close cooperation between the two auto industries, Mercedes-Benz, Volkswagen and other companies in the Chinese market to achieve sales, profitability improvement is just around the corner. The author believes that high-standard, high-level joint venture cooperation also symbolizes a more difficult game of interest. The two sides of the cooperation should be aware of what they can get from cooperation, what they have to pay, and accurately measure it. Therefore, as a partner, BAIC, FAW and other companies should pay more attention to the digestion and absorption of foreign advanced technology in cooperation, and then use it for me. These are more important than temporary profits and rankings. Some people in the industry bluntly said that with the good foundation of the German automobile industry, if the Sino-German automobile industry can maintain such cooperation and the Chinese enterprises can grasp the opportunities, then five years later, China is expected to become the world's best industrial base. .
