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.
