That is just what I was hoping to find with this thread. Someone with real world experience on this.
Everything in there grows when it heats up. We know that. The bearing and race expansion is not a factor at the operating temperature of the assembly. The cast steel bearing housing will grow very slightly, but negligible. The spindle will also grow, but I'm betting it will grow more in length ...
Therefore my thoughts, at this point are there would be +.000? atrunning temperature.
