The locating bearing at one end of the shaft provides radial support and at the same time locates the shaft axially in both directions.
The non-locating bearing at the other end of the shaft provides radial support only. It must also enable axial displacement so that the bearings do not mutually stress each other, e.g. when the shaft length changes as a result of thermal expansion.
