Overtightened Cooling Fan Belt
The belt attached to the left side of this bearing is overtightened, causing the top of the bearing to overheat. (This is a lower bearing, therefore the belt pressure is to the top.) The inset image shows a normal bearing (left) where the heat is transferring from the friction of the belt vs. the overheating bearing (right) where the main source of heat is the upward pressure on the bearing itself. Another important thing to note in this comparison, is that the same colors will not necessarily represent the same temperature ranges in different thermograms. The object parameters and image scale and levels will change these representations.
