Double-row ball slewing bearings have three seat-rings. The steel balls and the spacers can be directly arranged into the upper and lower raceways. Two rows of steel balls with different diameters are fitted according to the force condition. Such open mode fitting features are extraordinary convenient. The load angles of both upper and lower race way are 90°, which enable the bearing to convey large axial and the tilting moment. When the radial force is larger than 1/10 of the axial force the races should be newly designed.
We often provide other two types bearings as follows:
– Double-row ball slewing bearing (internal gears)
– Double-row ball slewing bearing (external gears)
-
As the axial and radial dimension of the such bearings are rather large, therefore they are especially suitable for tower cranes which require working radius over medium range and loader��
-
Here you will find details of such kind of bearings.
