Double Row Ball Slewing Bearings

double row contact ball slewing bearing is composed of inner ring, outer ring, double row ball, gasket, sealing device and other components. Since the top ball mainly bears axial load and overturning moment load, the size of the top ball is larger than that of the falling ball. In order to adapt to various working conditions under different axial loads, tilt moments and axial loads, the contact angle should be adjusted accordingly. double row contact ball slewing bearings can simultaneously bear axial load, tilting moment and radial load. The top ball mainly bears axial load and positive tilt moment. The falling ball is subjected to the opposite tilting moment. Therefore, the carrying capacity of the double-row ball slewing bearing is greater than that of the four-point contact ball slewing bearing.
