Double-row Ball Slewing Bearing

Main structural features: two rows of steel balls of different diameters are placed to bear the axial force and overturning moment. The most prominent feature is flexible rotation, but its carrying capacity is lower than the three row cylindrical roller slewing bearing. It is mainly used in machines with low load and high frequency, such as dock crane.Serial numberDesignationsBoundary dimensionsInstallation dimersionStructure sizeWithout gearDdHD1D2n?n1D3d1H1h1020.25.5006163841065804202018448247796262020.25.5606764441066404802018454353796263020.25.6307465141067105502418461360796264020.25.71082
