FWIW, here is some entertainment:
I found this bearing that is the same 32x62x17 mm size as the Roadster axle
bearing. It is a crankshaft bearing that is commonly used in Yamaha and some
other brands of snowmobiles and jet-skis. This particular one features a 3mm
roll pin in O.D. to prevent rotation in aluminum housings.
Further searching of info on this bearing has found the pin was removed in
order to use this bearing in a motorcycle application. I don't see why this
bearing can't be used on a Roadster as well. I thought I saw this bearing
somewhere, without the pin, but I'll have to keep looking through my search
files. I also believe you can get seals for it.
