Mouser:
72-MP06A-5000  Smaller shaft and bushing, but 12.5 watts. Pricey.
72-MP10A-5000  25 watts, right sized shaft and bushing. 1-9/16"
diameter. Pricey.
588-RHS-5K. Different vendor same as the previous part.
652-3852A-162-502A  $9.16, looks perfect if physically a bit small, but
the shaft, bushing, and power rating are perfect.

These are from the latest Mouser Catalog May-July 2005. There sure were
more to pick from a couple years ago.
