i went through this same nut roll earlier this year, the correct bearings were a b*tch to find.
you'll need 3 each- FAG 7201 BE 2RS AH01 (same as the INA 7201-BE-2RS-AH01)
i was able to find only one guy on the entire planet who has these:
dirk.schluecking@dswaelzlager.de
165 EUR for the three AH01's
you'll also need one INA NX12-Z.... I picked this one up locally
good luck!
