Double-row Ball Slewing Bearings

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.
