Double row ball slewing bearing
The double row ball slewing bearing has three seat rings , the steel ball and the spaces can be directly arranged into the upper and lower races. Two rows of steel balls are fitted according to the force born . Open mode fitting is extraordinary convenient .The load angles of both upper and lower race are 90°,which enable to bear large axial force and the tilting moment.
As the axial and radial dimension of the double row ball slewing bearing are rather large , structural is tightening and can support high static loads. They are mainly used in situations with variational load position and direction and continuously rotating . Especially suitable for tower cranes which require working radius over medium range , mobile crane and loading and unloading machinery .
