摘要：
For the axial securing of a spindle top part with respect to a spindle housing, it is known to provide the interior wall of the wharve bore with a collar which is in a detachable form closure with an elastic ring which is fixed on a front-face cover of the spindle housing. According to the invention, for the axial securing of the spindle top part, a retaining element is fixed on a sleeve which is fastened to an outer circumference of the spindle housing and projects beyond its top end face. When the spindle top part 2 is pulled off, such an internal securing arrangement prevents impairments which have a negative effect on the bearing seat of the upper bearing.
