The three row column slewing ring (13 series) has three seat rings, the upper and lower and radial raceways are separated respectively, so that the load of each row of rollers can be determined accurately.It can bear various loads together, which is one of the four products with larger bearing capacity, The shaft and radial dimensions are large, and the structure is firm, which is especially suitable for heavy machinery requiring large diameter, such as bucket wheel excavator, wheel crane, port crane, steel water transportation turntable and large tonnage truck crane.There are three types of products:No teeth(130),Outer teeth(131,132) and Inner teeth(133,134). This product is a heavy machinery column slewing ring and a no teeth Outer teeth Inner teeth slewing ring.

The three row slewing bearing is a slewing bearing ball belt type positioning cage, which is characterized in that the belt type positioning cage is mainly composed of a belt body, a ball seat hole, an upper circular arc boss and a lower circular arc boss. The row of roller type slewing bearings have three races, and the upper and lower and radial raceways are separated separately, so that the load of each row of rollers can be accurately determined.

Able to support various loads at the same time, it is a type of slewing bearing with the largest bearing capacity. The shaft and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel excavators and wheel cranes , Marine crane, port crane, molten steel operation platform and large tonnage truck crane and other machinery.This product is a bucket wheel excavators slewing bearing and a marine crane,port crane slewing bearing.
