Does anyone know of a formula to calculate the loading on the thrust bearing of a screw conveyor?

Need more info please
RE: Screw Conveyors
Mark's Handbook has a calculation for the power requirement but I can't find a formula for the thrust bearing load.
Thanks,

We have also been told that the screw must be 3/8" SS flights on a 6"eh SS pipe. Our understanding is that the mill has an existing conveyor of this capacity that has problems with the thrust bearing that they are looking to fix with the new conveyor.

Another probability is water contamination of the bearing. Make sure you can keep it dry. A problem can be a bearing gets hot while running in a wet environment. Due to some other problem, the machine is shut off for a short time. (even a fraction of a minute) The bearing cools, and water is drawn past seals which are in good condition. The bearing fails months later, but nobody remembers the brief shutdown.
You say the flighting is 3/4 pitch. Is this 3/4 foot or 3/4 of the OD? The usual pitch of flighting is between 1/2 and 1 times the OD of the flighting.
