If this option is activated, the shaft and housing temperatures are available as inputs in addition to inner and outer ring temperatures. This option should only be activated if a temperature gradient between shaft and inner ring or between outer ring and housing should be considered.
If this option is activated be sure to define all four temperatures especially if used from the shaft calculation. The shaft temperature in the shaft calculation will set the shaft temperature for the bearing, but the inner ring temperature still needs to be defined by the user.
