Hello,

Have a couple of Baldor/Reliance motors that I'm trying to identify the bearing number to add to my software.

The numbers are:

95BC02J30X
80BC03J30X
75BC02ZJ30X
55BC0ZJ03X


Thanks,
X

If you want SKF part numbers to match these AFBMA numbers, here they are
AFBMA          => SKF
95BC02J30X = 6219
80BC03J30X = 6316

75BC02ZJ30X = 6215
55BC02J03X  = 6211  [note I asssumed you meant 55BC02 not 55BC0Z because a Z wouldn't make sense in that position]

There may be some more suffix numbers if you wanted to buy identical replacement, but those numbers should be good enough for the fault frequencies. 

Most bearing manufacturers have siimilar pn's to SKF pn's listed above.  If I don't know the manufacturer I typically guess SKF. 

Maybe you can see the pattern:
BC in AFBMA number stands for "Ball, Conrad"....which means SKF pn starts with 6
2 or 3 in the 6th position of AFBMA number is dimension series... this translates to same 2 or 3 in 2nd position of SKF pn
First two digits of AFBMA number are bore in mm... divide by 5 to get  3rd/4th digits of SKF pn  (except for really small bearings, below 20mm bore I think). 

Sorry if I misunderstood the question.

Xracer,
You may be interested in looking into the ABMA to SKF app. I got it from Google Play, I would guess they have it for I phones too.

It is J30X for all these DGBB, where the 3 denotes C3 - greater than normal clr.- an important differentiation that Pete failed to mention. These brgs are sold in a box marked with suffix JEM through our distributor partners. J denotes steel cage like ABMA and EM is electric motor duty (used to be quality in the 70s & 80s). EM implies/includes C3 clr and GJN grease (Polyrex EM) when shielded or sealed.
