Why Replace an Idler Pulley?

A worn idler pulley can cause excessive belt wear, squeaking, poor belt tracking, increased motor load, and reduced equipment performance. Replacing a worn pulley restores smooth belt operation, maintains proper tension, and helps extend the life of your treadmill or other commercial fitness equipment.
