  1) For operation above 80% of the declared maximum coupling speed it is recommended that the coupling is
     dynamically balanced.
  2) Installations should be initially aligned as accurately as possible. In order to allow for deterioration in alignment
      over time it is recommended that initial alignment should not exceed 25% of the above noted data. The forces
      on the driving and driven machinery should be calculated to ensure that these do not exceed the manufacturers
      allowables.
  3) Weights and inertias are based on the minimum bore size.
