Hi Piero,
SKF has one with the right specs but polyamide cage: NJ306ECP/C3 SKF Cylindrical Roller Bearing - 30x72x19
Some info on this type of bearing: https://www.nortonownersclub.org/sites/default/files/Main-Bearings-v1.1.compressed.pdf
Regards

I found this in a very interesting document on the "Superblend" bearings. Would be interesting to hear if anyone have tried these bearings.
Here is the full document: ( It´s a lot of information but absolutely worth the time reading it through.)
On a side note the bearings in my 850 was composed of a NU outer race with a NJ inner race, which seems to be an ok mix.

NJ306E bearings can have an NU-marked outer race as NJ-NU outer races are identical.

Brass has a higher temperature rating than polymide, so the risk is the hot oil distorting a polymide cage and the bearing failing if the rollers break loose. I have fitted polymide caged roller bearing mains to a B44 engine and not had any issues in 5 years, but ask me in another 5 years and then I can tell you if it has worked or not.
