Double volley ball slewing bearing
The double row ball slewing bearing has three seat rings. The steel balls and isolation 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 kind of open assembly is very convenient. The load-bearing angle of the upper and lower 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 double row ball slewing bearing has relatively large axial and radial dimensions and a solid structure. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.
