According to my BOWER suppliers here in "Oz" BOWER have long since stopped manufac turing wound journal roller bearings B7118 (BOWER J24-1248) &B7121 (BOWER J24-1256) As have HYATT &RBC ALL we can source both here in Australia &overseas from bearing companies is KOBE which's chinese &both extremely poor quality (i.e. hardness of metal)&rollers are undersized
, i was recently quoted by 2x different bearing suppliers one quoted in Berliss brand &would retail here for $92.40 each (B7118) & $169.40 EACH respectively (prices quoted are in AUD), i'd strongly advise/suggest to either buy them from/off Ebay or try United Bearing Company Texas.
