i have changed the sc clutch bearing to NSK 32BD45DF, does anyone know what speed this bearing can handle? Code3 has NSK 32BD45DU.

Is there a typo on that bearing part number, because a google search brings up nothing except this thread?

I'm going through this process myself. after researching it for a whole day calling bearing suppliers, i came to only one :

the original bearing is : 32BD45DUM1

the new part number for the same item is : 32BD45-A-1T12DDUCG21

Measurements of stock old bearing is : 32mm inside diameter x 55mm outside and 23mm thick.

cost of bearing is 20.00+ shipping

place where i found it is :Applied Industries and Technologies Austin TX
phone number is : 512-929-8833

the bearing that code 3 sold aren't they rated at a higher rpm then the stock bearing? i know you can get the bearing on ebay if u look up supercharger bearing.

Lot of good info in this thread. In case it's of any use to anyone, according to my records the entire SC pulley assembly is:

MB P/N: 112-090-00-44
List: $1,444.50 (USD)

No Mercedes will not sell you just the bearing itself , you have to cough up the 1400.00 plus dlls for that if you want factory, but if you want specs to be exact just contact nsk the part number that i posted before is the exact part number or part that code 3 sells but half the price with out the mark up, it's still an nsk and rated at same specs.

I just got diagnosed with a bad clutch bearing in my supercharger. My regular repair shop said that I could replace the clutch assy (about $1350 for parts), but that they did not have all of the tools needed and recommended I go back to the dealer.

I've read where other posters have replaced just the bad bearing rather than the whole clutch assembly, but I don't know anyplace that I could have that done. I'm certainly not handy enough.

I'm in Louisville, KY

Any advice?

Any competent car shop should be able to replace the bearing for you. Make sure they use a press to press the bearing into the clutch. and be sure not to over-tighten the bolt that holds the bearing/clutch, cause it is hollow. search the forums for the exact torque. PM me if you need a bearing replacement.
