The Dodge D-LAG conveyor pulleys use a cutting edge natural rubber compound that is 73% more resistant to wear than standard SBR rubber. By increasing lagging life, the pulleys will extend the operating life of both the conveyor pulley and conveyor belt. The lagging is 100% vulcanized for pulley bonding and strength, making it resistant to cuts and gouges. The D-LAG MDX (mine duty extra) drum pulleys are available in diameters from 12 up to 24 in. These heavy-duty pulleys are designed with flexible end discs to eliminate weld fatigue under cyclical loads, while the MDX pulleys feature an integral hub design that eliminates the welded hub.
