    Radial load is negligible at the conveyor tail shaft. However, drive ends (unless integrated with the conveyor end plate) are subject to radial loading due to overhung drive loads, such as chain sprockets or shaft-mounted speed reducers. Thrust is the reaction, through the conveyor screw or screws, resulting from movement of the material.SCREW CONVEYOR CATALOG ENGINEERING MANUAL,The CEMA safety labels shown below should be used on screw conveyors, drag conveyors, and bucket elevators.
