The shaft shown below is secured with a flanged bearing on the smaller shaft. The far end is bolted solid to a plate so it can be fixed, but how would I correctly fix this end? Given that the bearing does not allow translation  perpendicular to the end but will allow a slight pivot about the center of the bearing it would seam like a slider/roller might be appropriate but I am not sure where I would place it for the correct freedoms.. Or do I model an additional "Knife edge" that the can be fixed and the smaller shaft rests on? I am interested in the deflection of the shaft when a uniform load is placed on it from the top. We have been asked to create an auger that is 1/3 longer than the current one and want to keep the deflection within the same range.
