Roadheader is mainly used for underground mining of coal and excavation of coal mine tunnels.

Its function is realized throughone or several pivoted and flexible rotating arms. The slewing bearing is the most critical component of the roadheaders, which not only carries extreme loads, but also transmits torque and force to the excavation drill bit.

Therefore, the high quality of the slewing bearing of the roadheaders requires multi-dimensional support, not only in the design itself, but also in the control of material selection and manufacturing accuracy.
