I guess what this really means is that the disc IS the hub - Lots of older VWs have the hub integrated into the rear discs, you have to push bearings the bearings into the disc itself
They later changed to a separate hub / disc, which is a more expensive assembly but the replacement discs are cheaper and less faff to change at service
