Thrust ratings vary greatly depending upon the transmitted power and the vertical shaft speed.
The ratings in the EXACT RATIO table are the axial loads that can be applied to the fan shaft
which will always result in a calculated bearing life greater than 100,000 hours L10.
These ratings are based on the worse case from the power rating tables.
All models can be supplied with larger thrust bearings or special bearing arrangements.
Contact the factory when the fan loading conditions or the bearing life requirements
cannot be satisified with the ratings from the tables.
