Allowable Buckling Load

  • ・Use this graph to select the correct frame number based on a specific buckling load, for compression loads.
    The buckling selection graph takes into account the buckling safety factor Sf=4.
    • (1)From the installation conditions shown in A and C below, determine the correct distance for LA and LC.
      (For installation conditions other than those shown in the diagram below, please click here. )
    • (2)The graphs allow you to select the correct frame number based on a specific load W (vertical axis) and stroke distance LA (horizontal axis).
  • ・Make sure side load does not apply.
    The graph below assumes no side load.
  • ・If the shaft is loaded in tension buckling can be avoided, and hence be highly economical.

  • Note)
  • 1.The dotted line on the graph represents an example based on W78.4kN {8tf} load (buckling safety rate of Sf =4) and installation condition C with a distance of 300mm.
    From this graph, JWB100/JWM100 is selected as the suitable frame number for these conditions.
