Wheel bearing part number

I got a wrong part delivered today while trying to swap the wheel bearing once again... The old one has two different inside diameters. The great and false new, just one.

What is striking is that the new two segerings (write that like that?) were there... The old one didn't have any... Does jmd have a shareummer for me so that I can not get another wrong one!? I had the same problem with the dom lagers... Diameter too big! How's the share number here?
