Recently, Meishan Aluminum Silicon Park has a total investment of 1.15 billion yuan in the form of a contract for a 200,000-ton/year high-performance wide-range rare-earth aluminum alloy sheet and strip project. This project fills the gap in the industry of wide aluminum panels in Sichuan Province and becomes a silicon-silicon park. Since the signing of the highest technological content of aluminum deep processing projects.
The project covers an area of ​​about 400 acres, the construction period is 22 months, after the completion of all production, it is estimated that annual sales income of about 3.8 billion yuan, profits and taxes of about 320 million yuan.
Meishan Aluminum Silicon Industrial Park is located in Xiuwen Town, Dongpo District, Meishan City. The park was established in May 2006. Since its establishment, the park has closely focused on the development of modern high-tech and high-energy-consumption industries based on the two major industries of aluminum and silicon, properly supporting the development of chemical industries serving the two major industries, and striving to form distinctive modern industrial clusters. Achieve "One key, three highlands" (ie Sichuan's key 100 billion industrial parks, and occupy the Sichuan aluminum industry, solar photovoltaic industry, cathode graphite carbon industry three strategic high ground) goals.
In recent years, the park has continuously innovated its service concept and opened up new models. In order to mobilize the enthusiasm of enterprises in the park to attract investment, at the beginning of this year, the Aluminum Silicon Park issued the “Measures for Inviting Merchants to Recruit Enterprises†to set up investment information awards and achievement awards for the enterprises in the park and related persons in charge. Those who introduced the project and contributed to the settlement will be given information awards and achievement awards respectively. The specific amount will be determined based on the investment scale and investment intensity of the project, and the maximum value shall not exceed 300,000 yuan.
The project was introduced by Li Yi, Chairman of Sichuan Meiyu Aluminum Co., Ltd. It is also the result of the park's innovative investment promotion methods and the strong promotion of business investment.
Thin wall ball bearings are simple in structure and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
Characteristics
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
