Tunnel boring machine (TBM) bearings are necessary for the efficient operation of these massive machines. ZZ has long been recognized for its expertise in producing these specialized components, breaking new ground in the field. Since 2010, ZZ has been supplying to customers such as CREG, these bearings have been integral to the success of numerous projects, including nuclear power plants and urban infrastructure developments, where reliability and performance are paramount.
In tunnel boring machines (TBMs), the cutter head main bearing is an important component that plays a central role in the operation of these machines. The bearing supports and guides the rotation of the main shaft, enduring significant axial loads, radial forces, and overturning moments. This type of bearing is predominantly used in TBMs, pipe jacking machines, and other tunneling equipment.
The drive disc is a key component in tunnel boring machines (TBMs). This essential part connects the TBM’s main bearing with the cutter head, ensuring smooth transmission of force and torque. Available in both integral and welded designs, the drive disc is highly adaptable for various tunneling and pipe jacking operations.
This combination of innovation, customization, and robust manufacturing capabilities positions ZZ as a trusted supplier in the TBM industry, ensuring reliable performance under even the most challenging conditions.
