Abstract

The invention relates to a bearing unit for the axial positioning of a shaft (15), said unit comprising a roller bearing arrangement provided with at least one axial bearing (5), and an adjustment means which is coupled to the shaft (15) by an adjusting thread extending axially parallel to the shaft (15) such that an axial relative movement between the shaft (15) and the axial bearing (5) results from the rotation of the adjusting means. A shaft liner (17) is provided, for example, as the adjustment means, with a thread for adjusting the axial position of the shaft liner (17) and therefore the position of the shaft (15). Alternatively, on an axial bearing (5), an inner ring (13) can comprise an axial extension (25) with an inner thread which engages in an outer thread of the shaft (15). It is also possible to combine a spacer ring (16) arranged on the shaft side between the radial bearing (3) and the axial bearing (5) with an adjusting sleeve (33) comprising an outer thread. The shaft (15) can be positioned by the rotation of the outer ring (9). Variations on the adjustment principle are possible.
