Idler Rollers
Idler rollers, or sometimes simply known as conveyor rollers, are cylindrical-shaped bars that run along and underneath a conveyor belt.There are many different types of idler rollers with varying functions. Usually, idler rollers aid in the supporting of weight and impact of the materials being transported along the belt.
