Old races - punched out

The old bearing races are out. I was not able to use the rental tool set -- The sizes of the punches didn't work for driving the old races out. But they will work to drive new races in.

The new races are in the freezer. Tomorrow, I will attempt to punch/drive them in --- w/o heating the hubs.

Here's a foto comparing new and old races. New and old, both are SKF bearings. New ones, from our host, are Made in China. The old ones --- inners are made in Germany; outers are made in Italy.

QUESTION: are bearing/race uniquely paired with each other? So for example, for inner bearings, I received two boxes from our host. One is box marked "1 of 2" ; the other box is marked "2 of 2". Would it matter if I used the race from box 1 with the bearing from box 2? I ziplock'd all the races and placed them in the freezer --- but didn't keep track of which race is from which box.
