Coupling Selection Procedure

  1. Select service factor (Table 1).
  2. Nominal power multiplied by service factor equals temporary designed power K.
  3. Designed power K should then be multiplied by factor L (Table 2) and S (Table 3). K x L x S
      gives the design power which is used for coupling selection in Table 4.
  4. Check from dimensional tables that chosen coupling has room to be mounted.
