EDIT ... for some reason, I had thought that the Karmen used a different Bearing than the other Aftermarket M112k SC pulleys used ...

I have the box in front of me and it is an NSK 32BD47 18T12DD (UKCG26). Rudy supplied this to me years ago as a replacement.



I am still running my Karmen as well although I think I have only put 75,000 miles on it . AND, my bearing started making noise years ago and I replaced it (with the bearing that Rudy got me).


Cheers,
Chris
