The diameter of inner ring bore ranges from 400mm-5000mm.  We can also produce the bearings with special dimensions according to your requirements.

 

The double-row ball slewing ring has three seat-rings.The steel balls and the spacers may be directly arranged into the upper and lower races.Two rows of steel balls with different diameters are fitted according to the force bom.

Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90° 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 disigned.As the axle and the dimension of the double-row ball slewing bearing are large,the bearing construction is lolidity;hence it is expecially suitable for tower cranes which require working radius over medium rage,mdile cranes and loading and unloading machines.
