The original design was a plastic type pulley with a -in bushing riding on a lubricated metal shaft. Under the constant pressure of the spring and the belt, running this type of configuration in a hot environment only cause the loss of lubrication, and a lot of heat be generated between the metal shaft and the bushing that holds the pulley. Soon, the heat builds up to a high level, so that the plastic pulley melts and the metal bushing starts to drag, thereby generating more heat. Then the melted pulley is separated from the metal bushing, causing the dryer to malfunction. This upgraded ball idler is an excellent design. First, replace the bushing with a ball bearing. Ball bearings can withstand greater loads and help reduce friction. point is that the ball bearing assembly is a sealed assembly. This prevents debris from entering the ball bearing and maintains internal lubrication. Therefore, the heat in the environment does not cause more liquid lubrication to escape the ball bearing assembly. Keeping the ball bearings lubricated ensures a long service life, and the bearing design itself helps keep friction heating to a minimum.
