Idler pulleys and fan hubs are not the same; they serve different purposes in machinery. An idler pulley is used to guide and tension a belt in a drive system, often found in engines or conveyor systems. In contrast, a fan hub is a component that connects the fan blades to the motor, allowing the fan to rotate and provide airflow. While both are mechanical components, they have distinct functions in their respective systems.

Why does your ford E350 van destroy serpentine belts?
There could be a number of answers for this problem. 1- are all of your pulleys in line. 2- has someone tried to turn one or more of he pulleys with a pair of pliers of pipe wrench and left burrs on the pulleys. 3- do you have bad bearing in one of the idler or the tension pulleys which could be making that pulley tip forward. Its also possible the fan clutch is seized, this causes undue stress on the belt when startup occurs.(personal experience) replace fan clutch and problem should dissappear
Do idler pulleys rotate?
ldle in english means to sit at rest or be still so i can see where this term may confuse you. but an idler pulley on a car rides on a bearing that spins. so YES it turns. it is used as an adjustment that your fan or SERPENTINE belt rides on . to keep tension on your belt. to clarify, the pulley by itself will not turn, it is turned by the motion of the belt moveing on in.

How do you replace the fan belt on a 1989 Buick Riviera?
There is a small braket at the bottom of the engine that needs to be removed to slip the old belt off and put the new one on. Remove it or loosen one end so you can get the belt around it. One of the pulleys is a spring loaded idler/tensioner for the belt. Use a wrench on the center bolt of this pulley to remove enough tension to allow the belt to slip off. Save this pulley for last when you put the new belt on and repeat the same operation with the wrench. There should be a diagram in the engine compartment to show how the surpentine belt goes around all the pulleys. If not, note how the belt runs before removing it.
