Double Row Different Ball Diameter Slewing Bearings

The double volleyball type slewing bearing has three seat rings. The steel ball and isolation block can be directly discharged into the upper and lower raceways. According to the stress condition, two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The bearing angles of the upper and lower arc raceways are 90 ° and can bear large axial force and overturning moment. When the radial force is greater than 0.1 times of the axial force, the raceway must be specially designed. The axial and radial dimensions of double row spherical slewing bearing with different diameters are relatively large and the structure is tight. It is especially suitable for tower type 。with medium diameter and above。
