1) Weight and Inertias are calculated using maximum bored standard hubs and minimum DBSE.
2) Maximum Unbalanced Speeds are based on AGMA 9000-C90 Class 9 with min DBSE and max interference bored coupling hubs.
3) Maximum Parallel Offset is based on a minimum DBSE ( 1/2 Deg. Angular misalignment per membrane pack).
