Structural characteristics, performance, scope of application
Three rows of roller slewing bearings have three races, and the upper and lower radial tracks are separated, so that the load of each row of rollers can be accurately determined. Able to bear various loads at the same time, it is one of the four products with the largest bearing capacity. The shaft and radial dimensions are large and the structure is strong. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel excavators, wheels Cranes, marine cranes, port cranes, molten steel operation platforms and large-tonnage truck cranes.
