A screw conveyor is disclosed with an end plate having an opening through which the shaft of the screw extends. The end plate has mounting holes symmetrically arrayed around the opening for the shaft to receive either an end plate bearing to support the shaft, or a bracket having a shelf on which a pillow block is mounted to support the shaft. The bracket can be mounted in a selected orientation to position the pillow block according to the requirement of a particular installation. A shaft seal is mounted on the bracket over the shaft opening.
