I suggest that you review the size of shaft proposed for the span of 600mm diameter screw indicated. ■

The size of the shaft diameter is a simple UDL deflection calculation. You don't want the flights to be scraping the bottom of the casing.

As a rule of thumb you shouldn't go much below 1:45 - so for 4500 mm between bearings you would be looking at a 100 DN tube. ■
