Structural advantages of three-row roller slewing bearing

Three-row roller slewing bearing includes upper ring and lower ring. The upper ring is connected to the lower ring by bolts to form an outer ring structure. The gear ring is located in the outer ring structure. A boss is provided on the side of the gear ring. An upper raceway is provided between the upper part of the boss and the upper ring. An upper row of rollers is arranged in the upper raceway. A lower raceway is provided between the lower part of the boss and the lower ring. A lower row of rollers is arranged in the lower raceway. A radial raceway is provided between the side of the boss and the outer ring structure. A radial roller is arranged in the radial raceway. A double sealing ring is connected to the inner edge of the upper ring and the upper end of the gear ring. A lower sealing belt is connected to the lower end of the gear ring.

The bearing capacity of each rolling element of the three-row roller slewing bearing is clearly divided. The upper and lower rows of rollers bear 90°, giving full play to the bearing efficiency of each bearing roller. Therefore, it has a large bearing capacity of axial force, radial force and overturning moment, which meets the requirements of engineering machinery, especially cranes, stackers, ladle slewing tables, etc. for 360° slewing bearings.
