Features of Slewing Bearings:
The double-row ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, the upper and lower rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The load-bearing angle of the upper and lower arc raceways is 90°, which can bear great axial force and tilting moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of the double-row reducing ball slewing ring are relatively large, and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium and above diameters.

It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium and above diameters.
The three-row roller slewing bearing has three races, and the upper, lower and radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can bear various loads at the same time. It is the largest bearing capacity of the four products. 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 wheels. Type cranes, ship cranes, port cranes, molten steel running platforms and large-tonnage truck cranes and other machinery.
