What Matters for This Task
A bearing housing or motor casing is an accessible surface, not a direct view of every internal part. Temperature comparisons become useful when machine load, operating time and viewing conditions are similar. A detailed image helps locate the observed surface pattern, while the maintenance record explains why that comparison was made.
