overturning moment and larger radial force

Single-row four-point contact ball slewing ring composed by the two seat, compact structure, light weight, and the circular raceway ball four point contact, can withstand the axial force, radial force and overturning moment. Rotary conveyor welding operation machine small cranes and excavators and other construction machinery can be selected.
(2) Single-row crossed roller slewing ring, composed by the two seat, compact structure, light weight, small assembly space for installing high precision cross roller arrangement is 1:1, can withstand the axial force, overturning moment and larger radial force, is widely used in material handling, construction machinery and military products.
3 three-row roller slewing angular contact ball bearing has three seat bottom and radial raceway separate from each other so that each row roller load can be determined exactly, can withstand the various loads, are the four products a maximum carrying capacity, axial and radial dimensions are larger firm structure, particularly for applications that require larger diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, ship cranes, ladle turret and large-tonnage truck crane and other machinery.
4 double-row slewing bearing has three seat, ball and isolation block can be directly discharged into the upper and lower raceway to the situation by force, arranged two rows of steel balls of different diameters. This assembly is very convenient, the upper and lower circular raceway bearing angles are 90 °, can bear large axial forces and tilting moment. When the radial force is greater than 0.1 times the axial force required specially designed raceways. Double-row slewing bearing axial and radial dimensions are large, solid structure, especially for applications that require above average diameter of tower cranes, truck cranes and other handling machinery.
5 double row ball slewing ring with a single row four point contact ball slewing bearing structure is basically the same structure, the difference is that the slewing ring has two rows of rolling elements. Can withstand the large axial load, radial load overturning moment. With a variety of cranes, excavators and other mechanical equipment
