Category:

Slewing ring bearing

Double volleyball slewing bearing has three seat rings, steel balls and isolation blocks can be directly arranged into the upper and lower raceway, according to the force situation, arranged the upper and lower two rows of different diameter of the steel ball. This kind of open assembly is very convenient, the bearing angle of the upper and lower arc raceway is 90 °, can bear a lot of axial force and tilting moment. The raceway shall be specially designed when the radial force is greater than 0.1 times the axial force. The axial and radial dimensions of the double-volleyball slewing bearing are relatively large, and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium and above diameter.
