FWIW I got about 40K out of my Shimano Ultegra 6700 BB. Sounds like yours lived a hard life and died young.

We talking bearings or BB shell here? Important distinction.
Shouldn't a BB shell last forever?? |

The mtb has some kind of pressed fit bb. It's over 3 years old and has been ridden in mud and wet sand and fine dust. It hasn't ever been serviced but it's very quiet and smooth. I was riding it 2 weeks ago and I could feel something dragging and thought it was the bb, turned out the lower jockey pulley was so gunked up I couldn't turn it with my fingers. Mr Maintenance strikes again. When we used square taper bb with ball bearings I would actually service them but still wore out some cups and axles. I had a cartridge-type square taper on my touring bike and it started clunking bad in Kansas or someplace and I took it apart at a motel and wrapped electrical tape around it and hammered it back into the frame and it worked! My second touring bike had a Phil Wood bb that was given to me. The thing had needle bearings and a little plug you could remove to inject oil. Super cool except the crankarm bolts kept loosening. |

Thanks for the help bah humbug, and Mo. Ended up ordering the one mo posted from CC.com. Should arrive in a couple of days.
Sweat problems, mine have multiplied since I started wearing glasses. Seems like it constantly falls on my glasses now. Makes seeing kind of hard. How long do bottom brackets usually last you guys/gals, and how often if at all do y’all service them. Mine had 6877 before it went kapooie. Mine has 5500 and is fine, I have the bearings replaced annually. Wear something on your head for sweat? I have an issue with it too. |

I think so.
But I am spoiled as all my road bikes have "standard" threaded bottom brackets which last a long time and are stupid easy to replace. So simple, even a caveman can do it. |
I've found that wearing a skull cap at an angle that leaves most of my forehead uncovered, plus squeezing the sweat out of the pads with my head tilted to one side, then the other, works for me. It may disgust anyone seeing an old guy squeezing sweat out of his helmet, but it beats having it run down the inside of my glasses. I tried a Sweat Gut'r headband under my helmet, but it didn't seem to work. I think the helmet squeezed the gutter closed at the ends, so all it did was to build up sweat till it poured over the rim.
Luckily, it's generally dry enough out here, especially when it's hot, that I don't have constant rivers of sweat running down my face. |
My current approach to BB bearings involves spreading my riding out among so many bikes that each one only gets a maximum of a thousand or so miles. The Canyon, which I got last July, and which has been my Sunday bike, only has about 1700 miles on it, for example.

Work being stupid is the story of my life - at least you got to ride today, I got to spend my morning learning that at 41 I have significant hearing loss on one ear and likely need a hearing aid unless an MRI turns up a mechanical cause.
