The three row roller slewing bearing has three races, and the upper, lower and radial raceways are separated, so that each row of rollers bears axial and radial loads respectively. It is the largest bearing capacity of the four products. The shaft and radial dimensions are large, but the relative diameter of the bearing is greatly reduced, which has the characteristics of making the main engine compact. It is especially suitable for heavy machinery that requires larger loads, such as bucket wheel excavators, wheel cranes, ship cranes, port cranes, molten steel moving platforms and large-tonnage truck cranes.
