Does anyone know how 100% ceramic bearings handle heat compared to steel bearings?
I know the best thing to do with motor heating issues is to use bigger motors with more copper, but its only the last .5 of a mile that causes my motor temps to jump. Everything else in the motors rated to 300 F and the hottest I’ve gotten them in 4wd was 246 F and that’s at the very end of my route. 3/4ths of the way through and I’m only at 170 F.
The current bearings are rated to 210 F, which I’m passing, and thus they are starting to dry out (lose lubrication) and I can’t see them lasting forever.
Do cermaics have any properties that make them better for high heat?
These ones I found on ebay look promising. Any thoughts?
