A spindle drive unit includes a spindle having a spindle axis and an external circumferential surface and a nut embracing the spindle and being in threaded engagement with the spindle. In an axial end portion of the nut a wiper assembly is removably fixed to the nut. The wiper assembly has at least one sealing ring in wiping engagement with the external circumferential surface of the spindle. The wiper assembly is removably connected to an adapter in a rotationally fixed manner, the adapter in turn being directly and removably connected to the nut in an axially and rotationally fixed manner. The use of the adapter enables the wiper assemblies of various constructions or with different numbers of sealing rings to be attached to a conventional nut.
