The invention relates to a spindle drive for adjusting the height of an electrically adjustable steering column and to the steering column itself. The spindle drive comprises an adjusting spindle (1) which is rotatably mounted in two bearings (6). The adjusting spindle (1) comprises two clamping elements (7, 11) which have a centering cone (7', 11') on the clamping element faces that face each other. The adjusting spindle (1) is arranged so as to be clamped against the two bearings (6) by means of the clamping elements (7, 11), wherein the clamping elements (7, 11) rest against the centering cone (7', 11') outer faces which face away from each other. The outer faces of the bearings (6) are formed with a mating contour for the respective centering cone (7', 11') resting against the bearing outer face. |
