Description

Double Row Ball Slewing Bearings The Double Row Ball Slewing Bearing has three seat ***** steel balls and the spacers may be directly arranged into the upper and lower ***** rows of steel balls with different diameters are fitted according to the force bom. Such open mode fitting features extraordinary ***** load angles of both upper and lower races are *0°, which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/*0 of the axail force the races should be newly designed. As the axle and the dimension of the double row ball slewing bearing are rather large, the bearing construction is sturdy , hence it is especially suitable for tower cranes which require working radius over medium range, mobile cranes and loading and unloading machines.
