A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can bore through anything from hard rock to sand. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil.
The three row roller slewing bearing has three seat rings,which separate the upper,lower and radial raceways,
it made each row of the roller's load capacity can be specified and can bear different loads simultaneously.
The capacity load is the largest one compare with the other three models.Due to the large size in axial and
radial dimension the solid structure, it is specially suitable for the heavy duty machinery such as wheeled
excavator,wheeled crane, ship crane,ladle turrets and the heavy duty mobile crane etc.
As the crane works in the environment of -20°C -- +45°C, this kind of slewing ring requires higher mechanical performance of materials.
