          Shambon Type Selection Calculation
           
          匯、Calculation for single-row ball slewing ring
          1、Capacity of slewing ring
           C0 = f ,D,d
           In EqualityCo !!Capacity of bearing kN
                  f !!Capacity factor 0.108 kN / mm2
                  D !!Diameter of track center mm
                  d !!Diameter of ball mm
          2、Loading calculation

           In EqualityCp !!Loading caculation  kN
                  M !!Toppling movement kN,m
                  Fa !!Axial force kN
                  Fr !!Radial force kN
          3、Safety factor calculation
             fs = Co / Cp
             fs see the following table。
          屈、 Calculation for 3-row-roller slewing ring bearing
          1、Capacity of slewing ring
           C0 = f ,D,d
           In EqualityCo !!Capacity of bearing kN
                  f !!Capacity factor 0.172 kN / mm2
                  D !!Diameter of track centermm
                  d !!Upper row roller diametermm
          2、Loading caculation
           
           In EqualityCp !!Loading caculationkN
                  M !!Toppling movement kN,m
                  Fa !!Axial forcekN
          3、Safety factor calculation
             fs = Co / Cp
             fs see the following table 。
