Double-row different ball diameter slewing bearings
- Performance of double-row different ball diameter slewing bearings:The double-row different ball diameter slewing bearings has three seat rings, and the steel balls and isolation blocks can be directly discharged into the upper and lower raceways. According to the force situation, the upper and lower rows of steel balls with different diameters are arranged. This open assembly is very convenient. The load angle of the upper and lower arc raceways is 90 °, which can withstand a 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 this ball slewing bearing are relatively large, and the structure is tight.
