1. A joining tool for pressing a disk (12) to a shaft (14), the shaft having opposite first and second ends (18, 24), the joining tool comprising:
a press table (22) for receiving the first end (18) of the shaft (14) in a nonrotatable manner;
a centering receptacle (26) for receiving the second end (24) of the shaft (14);
a press plate (34) for axially pressing the disk (12) onto the shaft (14); and
a resilient ram (40) formed from an elastically deformable material and provided on a side of the press plate (34) facing toward the disk (12) for compensating for an axial run-out of the disk (12) relative to the press plate (34).
