Ok, I guess this is a bit of a continuation of my earlier post regarding the front wheel bearings of a 54 9430. I found the B45 bearings new, and a set of NOS B46 bearings, but to my suprise when I recieved them they had the same wear groove on them as the ones I am replacing. Initially I thought that the wear groove was bad as only one of my bearing races had it and the other one did not. Now when I cleaned up the cosmoline on the NOS bearing races they have the same groove. I am now wondering if I bought these bearings for no reason if the groove on the race is "normal". Looking for some help on this one please. Is that little grove on the inner race normal on new bearing sets? The original bearings are the New Departure and these look like a 909046 from Sweden (pre SKF) I am thinking.
