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