Tunnel boring machines (TBMs) are used in transport and infrastructure projects. Alongside projects related to the construction of underground and overground railways and street tunnels, these also include water supply and sewage disposal projects. The main applications of these machines are cutting-head bearings, which are also called main bearings. Based on the hardness of the rock, thyssenkrupp rothe erde will develop the optimal cutting-head bearings, on a case-by-case basis, with the manufacturer of the machine. Bearings for road headers are also included within our scope of supply. These are used in mining, among other fields. Bearings for micro machines and vertical boring machines are available as supplements.
