The first domestic shield main bearing was successfully tested

With the shield machine equipped with the LYC brand shield main bearing, it succeeded in successfully merging the subway line crossing tunnel of No. 10 Yili Road in the downtown area of ​​Shanghai, ending the situation that domestic shield machines do not use domestically-made main bearings. The situation in the construction machine market will change accordingly.

The shield main bearing is one of the core components of the shield machine. Due to the influence of operating conditions, it has strict requirements on the accuracy of the product and the reliability of operation. Its core technology is controlled by a few well-known bearing companies in the world and has a monopoly. Global Shield Machine Bearing Market. In order to break the monopoly, the state has included the development of shield main bearings in the national 863 plan and handed it over to LYC for development. To this end, LYC, as the main research unit, took the lead to form a strong technical R&D team, carried forward the pioneering spirit, and gave full play to the solid technology research and development advantages that the company had accumulated in material applications, product design, manufacturing, testing, and experimentation for decades. Innovative design and application have overcome more than 10 key technical issues and achieved many breakthroughs in the research of core technologies. They have obtained 6 national patents and proprietary technologies. After three years of research, the mission was successfully completed.

Subsequently, LYC Corporation, under the strong support of a well-known domestic company, boldly installed LYC bearings on the shield machine of Shanghai's bustling road section. LYC dispatched a technical team led by the chief engineer to track the service on site.

According to the technical person in charge of the construction party, the excavation work of the road section has been successfully completed. The main bearing of the shield machine has been working steadily with uniform torque throughout the excavation process, and it can fully meet the requirements of the shield bearing machinery for the main bearing. At the same time, according to the company's project arrangements, the bearing will continue to be applied in other subway projects. At this point, LYC Bearing once again demonstrated its excellent quality and brand value to the world with absolute strength, which laid the LYC company's manufacturing R&D level in such product areas and continued to maintain its leading position in the country.
