In the first eight months of this year, the orders for cutter head bearings of shield machines of China increased by 125% over the same period of last year.        In the fourth quarter, the orders continued to grow at a high speed, with an average of tens of thousands of sets per month.
The shield machine, known as the "king of engineering machinery", is a "national important tool" integrating machinery, electrical, hydraulic, sensing, mechanics and other technologies.        Due to the particularity of the working conditions, the supporting bearings of shield machines have high requirements for production technology, and China has long relied on imports.

In recent years, China has accelerated the research and development of cutter head bearing of shield machine, constantly tackling core key technologies, and has replaced imports and provided support for customers in batches.        The accuracy of cutter head bearing of shield machine is required to be high, especially the machining of raceway crown is extremely difficult.        The engineering technicians and operators of the company closely cooperate with each other to continuously optimize the processing technology, ensuring that the product raceway crown meets the standard requirements, while the processing efficiency is increased by 30%, and the production cycle is shortened in an all-round way.

There are more and more orders. we will continue to work hard to catch up with orders . we have confident of continuously creating new records in the production of cutter head bearings of shield machines.
