Triple row cylindrical roller combined slewing bearing consists of three bearing rings. The adjusting spacer between upper bearing ring and lower bearing ring can adjust the axial internal clearance. which dia from 3000mm to 8000mm, material always use50Mn, 42Crmo .

Upper row rollers and lower row rollers are distributed horizontally, so as to support the axial forces and tilting moments from two directions. While radial force is supported by the third row rollers that are vertically distributed.

Since our triple row cylindrical roller combined slewing bearing is firm in structure and large in axial dimension and radial dimension, it is quite suitable for use in heavy duty machinery, such as bucket-wheel excavators, wheel cranes, ship cranes, port cranes, molten steel operating platforms, and so on.
