FWIW, The only cartridge BB I has fail was a Tange LN-3922, made in Japan. So much for origins ...... Meanwhile the Shimano UN series just keeps on spinning and I can't say how many miles. But for the $15 I paid for them, that buys many of them in contrast to a high falootin' bottom bracket, which guarantee you nothing in durability terms. Phil bearings on their BB's can be user replaced though can't they ? Despite what they may claim. Also, where the bearings or races really corrupt, or did they simply need some cleaning and grease, popping off the seals yourself ?
Any bearing assembly is a crap shoot. I'm still running the orignal bearing on a Specialized cartridge bearing hub from the mid 80's. I cleaned repacked it once. It's a superior design to purely exposed cartridges as it also has a metal shield over the bearings. But I know, we're talking BB's here. In summary, my premise is the inexpensive Shimano BB's get terrific mileage for the price. This was with the UN54/55/70 series, I can't speak to he newer 300 series. No, one doesn'gt always get what one pays for ans everyone knows it. One "payz what theyz pays, so to speak, no guaranteez".
