Excessive wear can lead to lost production due to the maintenance involved in changing out a pulley. PPI’s proprietary rubber compound used in AR lagging has been proven in a controlled abrasion test to demonstrate roughly twice the resistance to mass loss as standard SBR. AR lagged pulleys are equipped with a wear indicator strip notifying maintenance personnel that the lagging has worn to a point that scheduled maintenance should be planned. This improved abrasion resistance leads to extended replacement intervals, resulting in a lower cost of production.
