1) For operation above 80% of the declared maximum coupling speed it is recommended that the coupling is dynamically balanced.
2) Installation 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 calculated with mean bore for couplings up to and including PM 600 and with maximum bore for PM 900 and above.
4) Oversize shafts can be accommodated in large boss driving flanges, manufactured to customer's requirements.
5) PM 0.4 - PM 3 driving flanges are available with solid bores on request.
