My question is not Norton but close enough for me to ask on this list I hope: For crankshaft ball bearing
SKF 6209 I want to use a sealed bearing as I have a BNR belt drive. SKF make a 2rs1 bearing
but it is only good to 195 degrees F. They make a higher temperature rated 2rs2 which goes
to 300F or nearly so. Naturally I want a C3 clearance and I see that many higher heat range
sealed bearings are C5.
The problem is that they are only rated to spin at 5200rpm which falls a bit short of my
red line which is 6000.
The bearing doesnt have to be a SKF of course. Am I just asking for too much or does
one of the boffins aboard have some guidance for me here?
