2 Allowable Misalignment (2)
(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.
