Tunnel Boring Machine Bearings | Slewing Bearing Manufacturer

Tunneling

Tunnel Boring Machine Bearing Solutions

The main bearings in tunnel boring machines (TBMs) are significantly important in the excavation process, connecting the shield and the main drive to facilitate the rotation of the cutterhead. These bearings endure significant axial forces and torque within the confined space of the TBM, making their durability and reliability essential for the success of any tunneling project.

Our Advantages

Since 2009, ZZ has been engaged in the refurbishment of TBM main bearings, accumulating extensive experience and laying a solid foundation for the domestication of these critical components.
We not only manufacture main bearings but also produces the associated main drive and spherical bearings, providing a comprehensive understanding of the supporting components and ensuring reliable design, development, and production of main bearings.
We have developed enhanced materials by improving upon the 42CrMo4 steel, resulting in higher-performance bearings.
We use advanced induction hardening technology without a soft zone, significantly increasing the strength and lifespan of the bearings compared to conventional methods.
We have manufactured TBM main bearings, associated ring components, segmental machine bearings, and spherical bearings for TBM manufacturers.
Our team can conduct detailed strength and life expectancy calculations based on the operational conditions provided by customers, ensuring precise and reliable design.
