Crawler-type rotary drilling rig is a small and medium rotary drilling rig developed by us for civil engineering, municipal construction, and railway, bridge pile foundation projects. For the rotary drilling machine, we suggest to use the three row roller slewing bearing, it 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.

In addition, we selected 42CrMo as the material, it has better metal properties for quenching and tempering heat treatment, so that the hardness of the material itself reaches HB240-280, which lays a solid foundation for increasing the service life of the slewing ring/turntable bearing and improving the load-carrying capacity.
