Double Row Ball Slewing Ring Bearing
Different diameter ball slewing bearing has three seats ring,the steel balls and the spaces may be directly arranged into upper and lower raceways.Ingeneral dia from 1000-3500mm,two rows of steelballs with different diameters are fitted according to the load.such open mode fiting features are very convenience.
The load angles of both upper and lower race are90,which enable the bearingto bear large axial froce and the overturning moment.when the radial force is larger than1/10 of the axial force .the raceways should be especial designed. the axial dimension and radial dimensionof double-row ball slewing bearing are rather large.
Double row slewing bearing be widly used on Large cranes,Marine Cranes,Wind turbines, Telescopes and Mining equipment.
