It can be directly discharged into the upper and lower raceway, and arranged different top and bottom diameter balls based on force status. The assembly is very easy to open. Up and down raceway arc angle is 90 degrees, it can withstand large axial force and overturning force. When the radial force is more than 0.1 times the axial force, the raceway require special design. The axial and radial dimensions of double-row slewing bearing are large, and solid structure, especially suitable for that require above average diameter of the tower cranes, truck cranes and other handling machinery
they widely used in material handling equipments, mining machines, construction machinery, port machinery, wind power generation, medical equipments, radar and missile launchers and other large rotating devices.
