Jim,
If you plan to use a sealed bearing(1 row or 2???) - consider specifying a hybrid ceramic bearing with a high temperature rating including Viton seals. There was some discussion about venting the seals to prevent the seals being forced open when the grease gets hot . Some of these bearings are already vented. .The temperature rating of the seals and grease is more important than the ABEC/DIN number Imho.
