Double volley slewing bearings (02 series) -- toothless

Structure characteristics, performance, scope of application

The double volleyball SLEwing bearing has three seat rings, and the steel ball and the isolation block can be directly discharged into the upper and lower raceway. According to the stress condition, the two rows of steel balls with different diameters are arranged. This open assembly is very convenient, the upper and lower arc raceway bearing Angle is 90°, can withstand a large axial force and roll 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 volleyball slewing bearing are relatively large and the structure is tight. Especially applicable to the requirements of medium diameter tower crane, truck crane and other loading and unloading machinery.
