The double-row ball slewing bearing has three seat-rings.The steel balls and the spacers may be directly
arranged into the upper and lower races.Two rows of stell balls with different diameters are fitted according to the force.
Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90 degrees,which enable the bearing to bear large axial force and the tipping moment.When the radial force is larger than 1/10 of the axial 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 conatruction is firm.
It is expecially suitable for tower cranes which require working radius over medium range,auto-mobile cranes and unloading machines.
