We've got  GE 150 HP motor with this bearing listed on the drive end. I can't find anything that cross-references the BL designation. BC's and RN's are easy, not this one.

Anyone got any suggestions?

I would say its a 318 bearing with maximum capacity, pressed steel cage, a shield on both sides of the bearing.
12 balls- ftf .387
bsf 2.091
bpfo 4.639
bpfi 7.361

I agree. 90BL03JP
90 -> 90mm bore.  90/5=18 
BL -> max capacity
03 ->  300 series. 
(That's all you need for frequencies)
J -> pressed steel cage. 
P - I tend to think that means single shielded (PP for doubleshielded). But it doesn't affect the frequencies one bit.

Thanks all! I had a similar chart from long ago but had all the Bx descriptions except for the BL.

Also found this website (http://abcmechanics.com/bearings/) in case anyone hasn't seen it.
