No, the AE-G22N has a standard #12 hub. The #22 in the description stands for the size of the meat grinder, not the size of the hub.

You will be able to use all our other #12 hub attachments on the motor unit: AE-TS12H tenderizer, AE-JS12H jerky slicer, AE-MC12NH meat cutter, AE-VS12NH vegetable shredder/slicer, AE-G12NH/AE-G22NH meat grinder, and AE-GMC22NH large capacity meat cutter.
