Hmmm,
Reread the little numbers on the original bearings. The stuff after the 1st 4 numbers doesn't matter so much. A 3 can look like a 2, 5 look like 6's etc. Wipe them clean, and use a magnifying glass.
6002 is 15 32 9

6003 is 17 35 10
6902 15 28 7
6903 17 30 7
There is a mistake somewhere. Carefully remeasure your original bearings- .040"= 1mm. It will tell you what you have.
Luck,
