The double volleyball slewing ring has three seat rings. The steel balls and spacer blocks 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 open type assembly is very convenient. The bearing angle of the upper and lower circular arc raceways is 90 °, which can withstand large axial force and tipping 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 double row reducing ball slewing bearings are relatively large, and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes with medium or above diameters.
