The temperatures of the inner and outer ring are used for the calculation of the interference fit between shaft and inner ring or between housing and outer ring only. They affect the operating clearance. Optionally the temperatures of the shaft and housing can be entered too to consider a temperature gradient.
The temperature of the rolling element is assumed to be the maximum value of the ring temperatures as default. This can be changed under settings and a manual input of the rolling element temperature is available optionally too.
